Industrial battery regeneration system made up of the MMF universal charger and an automatic discharger **An industrial battery that loses capacity through sulphation can be recovered by dissolving the hardened sulphate and then measuring the improvement with a controlled discharge.** The Amperis Battery Regenerator combines the universal, programmable MMF charger, which applies a high-frequency ripple current to dissolve the sulphate and restore it as active material, with an automatic discharger that measures the discharge time before and after regeneration; the charger reaches 600 V DC, with a fully configurable charging curve and efficiency and power factor above 90 %. The Amperis battery regenerator successfully removes sulphation, removing lead sulphate, restoring battery capacity and extending the life of old, sulphated batteries. The regenerator can also be used for annual maintenance. The great advantage of the Amperis Battery Regenerator System is the ability to dissolve the hardened sulfate in the battery terminals and restore it as active material. To remove the hardened sulphate the equipment applies a high frequency ripple current. The Amperis Battery Regeneration System consists of a state-of-the-art battery charger and a battery discharger: The MMF charger is a universal, controlled and programmable charger; it works with any type of battery efficiently thanks to the high frequency IGBT hybrid technology. It can reach up to 600 VDC output and ranges from 50A to 300A. With this charger it is possible to customize the charging curve. Automatic battery discharger designed to test the efficiency of industrial batteries of any type, voltage and capacity. For batteries up to 600V, possibility to put several units in parallel, which allows the discharge at any current, with high frequency IGBT regulator, which allows the discharge at constant current. Battery regeneration can be either reconditioning (allows old batteries to be conditioned giving them more years of life) or maintenance (allows the battery to be kept in an optimum sulphate-free state by performing a short annual regeneration). Reconditioning battery regeneration: the best option for old batteries that are working below their optimum level due to sulphation or to revive batteries that have lost charge capacity because they have been out of use for a long time. We can see from the graph below that after the 4th year of battery life, the capacity and performance of the battery collapses. By regenerating the battery, we recover it and get it to operate at good levels. Regeneration of the reconditioning battery Maintenance battery regeneration: the best option to extend the life of new batteries, making it possible to double their life and keep them at their maximum productive capacity. Performing this maintenance, the battery improves its long-term performance by doubling its output. The regeneration of the maintenance battery The level of regeneration acquired by the battery must be measurable to quantify the improvement in the battery. To achieve this the most accurate methodology is that used by the Amperis Battery Regeneration System, which uses a battery discharger that allows 100% measurement of the battery discharge time before and after regeneration Applications: - Starter batteries - Stationary batteries - Batteries for solar, wind, emergency, UPS systems. - Traction batteries - Ni-Cd batteries The problem of sulphation: The life of more than 80% of the batteries is reduced by sulphation. Lead sulphate inevitably builds up on the electrodes, increasing internal resistance. The causes of sulphation are inherent in lead-acid batteries, but there are other reasons such as battery inactivity, deep discharge or failure to comply with charging cycles, among others. The accumulation of sulphate crystals on the battery electrodes prevents the battery from effectively supplying current. This process accelerates over time hence the importance of regenerating the battery. Advantages: - 70% of the batteries that are discarded are due to sulphation problems. There are several reasons why battery life is shorter than estimated: - Generation, accumulation and deterioration of lead sulphate - Reduction of electrolytes caused by electrolysis - Corrosion - Loss of active materials The regeneration of batteries is a very profitable practice because it saves on the purchase of new batteries, reduces the energy bill and eliminates the costs of technical incidents and maintenance. Furthermore, it must be taken into account that the regeneration of batteries contributes to the improvement of the environment, since if the battery is not regenerated it must be discarded, being the waste highly toxic: - Savings in maintenance costs - Savings on battery replacement (longer life) - Savings in equipment repair (less technical incidents) - Savings on replacement of components - Labour savings and maximum productivity - Savings in waste generation and treatment (waste reduction) Energy cost savings ### Amperis Battery Regenerator key data - **System:** MMF universal, controlled and programmable charger with high-frequency IGBT technology, plus an automatic battery discharger; reconditioning regeneration or annual maintenance regeneration with the same equipment. - **MMF charger output:** from a single cell up to 600 V DC; standard models 0-48 V up to 300 A, 0-80 V up to 150 A, 0-96 V up to 200 A, 0-200 V at 80 A and 0-400 V at 50 A; charging curve fully configurable by the user. - **MMF charger input:** single-phase 220-230-240 V AC ±10 % or three-phase 220-240, 400, 440, 480 or 600 V AC ±10 %, 50/60 Hz ±5 Hz; efficiency and power factor above 90 % (average values over the full charging cycle). - **MMF protection:** stand-by with error message on wrong battery or reverse polarity, electronic short-circuit and overload protection, anti-arcing with auxiliary wires, self-test at each power-up (<10 s), shutdown in under 3 s if the battery is disconnected, and cycle resumption after a mains blackout. - **Discharger:** standard models 12-48 V at 100 or 200 A, 12-96 V at 200 A, 24-135 V at 150 A and 48-220 V at 75 A; display of voltage, current, discharged capacity (Ah), stop voltage and times; 48 h maximum discharge time and RS-232 interface (USB on request). - **Logging and environment:** 200-cycle memory in the MMF (600 with optional miniUSB) and Bluetooth extension; IP21 enclosure as standard and IP54 optional, noise below 65 dBA at 1 m and operation from −10 to +50 °C. - **Standards:** CE; IEC EN 61000-6-2 and IEC EN 61000-6-4 (EMC); IEC EN 50178 and IEC EN 62040-1 (safety); UL 1564, CSA 22.2 107.2-01 and cCSAus. - **Applications:** starter, stationary, traction and Ni-Cd batteries, and batteries for solar, wind, emergency and UPS systems; formation, conditioning, recovery and desulphation. ### Frequently asked questions **How do I prove that regeneration has recovered the battery?** With a controlled discharge. The Amperis Battery Regenerator includes an automatic discharger that measures the battery's discharge time before and after regeneration and shows the discharged capacity in Ah, with discharges of up to 48 h and data transfer to a PC over RS-232. **When should I choose maintenance regeneration instead of reconditioning?** Reconditioning is for old batteries working below their optimum level because of sulphation, or that have lost capacity after a long time out of use; maintenance is a short annual regeneration that keeps new batteries free of sulphate to extend their service life. Both are done with the same Amperis Battery Regenerator: MMF charger and discharger. --- ## Acoustic Camera URL: https://amperis.com/en/products/cameras/corona-effect-cameras/acoustic-camera/ Category: [Corona Effect Cameras](https://amperis.com/en/products/cameras/corona-effect-cameras/) Series: Corona Effect Cameras datasheet: https://amperis.com/18136-Ultrasonic-V3-English.pdf > Acoustic camera: ultrasonic camera with 112 MEMS microphones, 2 to 100 kHz, 0.5 to 200 m, to locate partial discharge, gas leaks and abnormal noise.

IBAR injects 1.5 to 150 mA depending on the scale, measures 0 to 5 Ω with resolution from 1 µΩ and gives each reading in about two seconds, together with the cell voltage when the U+R mode is used. **Which tester suits cells with an internal resistance of only a few milliohms?** One with microohm resolution and enough test current on the lowest scale. IBAR measures up to 5 mΩ with 1 µΩ resolution, 150 mA test current and ±(1.0 % of reading + 0.1 % of full scale) accuracy; from 5 to 50 mΩ, with 10 µΩ resolution and ±(0.8 % + 0.1 %). **Why measure internal resistance and not just voltage?** Because a cell can show a normal voltage and still be degraded; internal resistance grows with ageing and anticipates the failure much earlier. **Does the battery have to be disconnected?** Yes. The device is designed for offline batteries, disconnected from the charger and the load, which removes interference and makes measurements repeatable. **How do I know a cell is bad?** By defining thresholds in advance: during the test each reading is automatically compared and flagged PASS, WARNING or FAIL. **Can I compare measurements from different campaigns?** Yes. All readings stay in memory with time and date, and the PC software builds per-cell trends to compare them between inspections. --- ## IMT-40: insulating mats testing stand URL: https://amperis.com/en/products/insulation-resistance-meters/dielectric-tests/imt-40-stand/ Category: [Dielectric test sets for insulating PPE](https://amperis.com/en/products/insulation-resistance-meters/dielectric-tests/) Series: dielectric-tests > IMT-40: dielectric testing stand for insulating mats up to 1200 × 1200 mm at 40 kV AC, to IEC 61111 and ASTM D1048; 120 kg without electrodes.

Conductivity, relative permittivity and tanδ meter for insulating oils to IEC 61620 **Assessing the quality of an insulating oil by its conductivity and dissipation factor (tanδ), even at room temperature, takes an IEC 61620 meter applying a low-amplitude, low-frequency alternating square wave, a method far more sensitive than the bridge method.** The TAND220A excites the 210 ml sample with ±30 V at 0.5 Hz without DC component and measures conductivity from 0.01 to 20,000 pS/m with ±1 digit ±1 % of reading, relative permittivity up to 5.00 with ±1 digit ±0.2 % and tanδ values down to 10−6 (at 50 Hz), with a test voltage and current that pose no danger to the operator. TAND220A Dielectric Oil Delta Tangent Meter The measuring instrument type TAND220A complies with the international standard IEC 61620. The instrument is based on the so-called "low-amplitude, low-frequency alternating current square wave method" and allows accurate measurements of conductivity and relative permittivity. Conductivity measurement in the range of 0.01 pS/m to 20,000 pS/m allows the use of this instrument for quality control of high resistivity liquids even at room temperature. The TAND220A works with a low test voltage and also with a low test current so that it does not represent a danger for the operators. Measurement method The liquid in the test vessel is excited with a low amplitude (30 V), low frequency (0.5 Hz) and square alternating wave without a continuous component (see figure 1). By measuring the current flowing through the liquid, the capacity C and conductance G can be determined and the values of relative permittivity εr and conductivity σ are provided according to the following equations εr = C/Co σ = εo.G/Co The dissipation factor derived tanδ for a given frequency f can be determined by the following equation: tanδ = G/C-2 For the determination of conductivity or tanδ, the alternating square wave method is far more sensitive than the bridge method. It allows the determination of conductivity down to values as low as 0.01 pS/m and values from tanδ as low as 10-6 (at 50 Hz). This high sensitivity allows conductivity and tanδ measurements at low temperatures and therefore the characterization of liquids at room temperature can be performed safely. Test vessel The application of the square-shaped excitation voltage with a low amplitude of only ±30 V allows the development of a test vessel with a simple, easy to use and clean design. The test vessel of the TAND220A consists of only two parts, a container and an active part. Two coaxial electrodes (stainless steel) are installed in one vessel (also stainless steel). This beaker also holds two BNC connectors attached to the two electrodes. The electrodes have a clean and polished surface. The vessel and the active part can be cleaned according to procedures described in appendix A. It is not possible or necessary to disassemble the active part for cleaning. The required amount of liquid for the test is 210 ml. To reach this amount fill up to 23 mm from the end of the vessel with liquid. The temperature of the liquid can be determined by inserting an electronic thermometer into the vessel through the hole in the lid. Application A typical application of TAND220A is the quality control of mineral oil used as a dielectric fluid in high-voltage switchgear such as power or measurement transformers, capacitors, terminals, etc. Several studies have shown that the conductivity of the oil is influenced by impurities and ionic components, which were introduced into the oil or were produced in the oil. Therefore the conductivity of the oil characterizes well the quality of the oil. On the other hand it has been proven that moisture dissolved in oil does not significantly influence the conductivity. The following conductivity values at room temperature are typical depending on use: - New oil (laboratory quality) ≤ 0.05 pS/m - New oil (industrial quality) 0.05...0.1 pS/m - Oil with little use in good condition 0.1...1.0 pS/m - Oil with average use in acceptable condition 1.0...5.0 pS/m - Heavily used oil in bad conditions > 5.0 pS/m **Specifications** **Conductivity measurement range** | 10-14 ... 2'10-8 S/m in four ranges **Uncertainty of conductivity measurements** | ±1 digit ±1% of reading **Measurement range of relative permittivity** | up to 5.00 **Resolution of the permittivity measure** | 0.001 for relative permittivity up to 1.999 **Uncertainty of permittivity measures** | ±1 digit ±0.2% of reading **Frequency of voltage measurements** | 0.5 Hz **Voltage measurement range** | ±30 V square wave without continuous component **Analog outputs** | 2 V from 0 to 100%. **Weight** | 2.6 kg **Size(width ' depth ' height in mm)** | 260 ´ 283 ´ 115 **Food in the field** | four AA batteries **Food in the laboratory** | 100 ... 240 Vac 50/60 Hz **Operating temperature** | 0¼35°C **Vessel** **Amount of liquid required** | 210 ml **No load capacity** | ≈ 60 pF **Derives from capacity with temperature** | < 50 ppm/°C **Distance between electrodes** | 1.5 mm **Temperature measurement** | electronic thermometer **Weight** | 1.2 Kg **Size (height ' diameter in mm)** | 125 ´ 82 Table 1: Electronic measuring instrument **Optional equipment** | Z1 Vessel heater The instrument heats and maintains the temperature of the samples at a temperature of 90ºC ± 0.1°C to perform the measurement in accordance with the IEC standard. | Z2 Vessel for continuous measurement The vessel for continuous measurement from tanδ in an oil circuit like that of an oil treatment plant.

The TAND220A measures from 0.01 to 20,000 pS/m, so it covers the whole span with ±1 digit ±1 % of reading. **Can the TAND220A be used in the field or for continuous measurement?** Yes. The TAND220A weighs 2.6 kg and runs on four AA batteries in the field or on 100-240 V AC in the laboratory.

Breakdown voltage test set for insulating oils up to 90 kV **Measuring the breakdown voltage of an insulating oil to IEC 60156 takes a test set that raises the voltage at a controlled rate between standard electrodes, disconnects at the instant of breakdown and computes the statistics of the test series.** The OT-90 applies 10 to 90 kV at 2 kV/s with a 3 % measurement accuracy, uses 25 mm radius mushroom-profile electrodes and delivers the mean and standard deviation automatically, for both mineral and synthetic oils. ### OT-90 key data - **Test voltage:** the OT-90 applies 10 to 90 kV on the electrodes, with a 2 kV/s rise rate and a 3 % voltage measurement accuracy. - **Standard and electrodes:** testing to IEC 60156 with 25 mm radius mushroom-profile electrodes, for mineral and synthetic oils. - **Programmable cycle:** the test voltage value, rise rate, test time and sample mixing time are programmed; the OT-90 disconnects at the instant of breakdown and repeats the sequence. - **Statistics:** it automatically computes the mean of the measurements and the standard deviation, the two figures with which IEC 60156 characterises the dielectric strength of the sample. - **Result logging:** built-in thermal printer for the test ticket and a Bluetooth link to a computer that controls the set, stores the results and prints the reports. - **Safety:** interlock preventing voltage from being applied with the cover open. - **Power supply:** 230 V (50±2 Hz) with 0.5 kW consumption, and an internal battery for up to 8 h of autonomous operation. - **Environment and size:** 0 to +35 °C with relative humidity below 80 %; 520 × 335 × 320 mm and 35 kg. ### Advantages **Standardised testing up to 90 kV** The voltage on the test electrodes spans 10 to 90 kV with a 2 kV/s rise rate and a 3% measuring accuracy; the mushroom-profile electrodes with a 25 mm radius follow the guidelines of IEC 60156. **Configurable test programme** Test voltage value, voltage rise rate, test time and mixing time are all programmable to match each laboratory procedure, and the instrument automatically calculates the mean of the measurements and the standard deviation. **Results documented on the spot** The built-in thermal printer delivers the test ticket in the field; over Bluetooth, the set is remote-controlled from a computer, which stores the results and prints the reports. **Laboratory-grade safety** A safety interlock prevents power from being applied while the cover is open, and the ergonomic layout supports the correct execution of the test procedure. **Full-day autonomy** The internal battery powers the set for up to 8 hours, so oils can be tested where no mains supply is available. ### Applications - Laboratories of transformer manufacturers and maintenance service companies. - Oil condition checks on oil circuit breakers, instrument transformers and capacitors. - Periodic dielectric strength verification in substations. - Checking oil after filtering or regeneration processes. ### About the product The working cycle automates the complete test: programmed mixing of the sample, voltage rise at 2 kV/s, cut-off at the instant of breakdown and repetition of the measurements until the statistics required by the procedure are complete, with the mean and standard deviation computed without operator input. The unit measures 520 × 335 × 320 mm, weighs 35 kg and runs from 230 V (50±2 Hz) with a 0.5 kW consumption, operating from 0 to +35 °C at a relative humidity below 80%. Available accessories: test cell with standardised electrodes, temperature probe, Bluetooth adapter and PC remote-control software. ### Technical specifications Test voltage | 10 to 90 kV Voltage rise rate | 2 kV/s Voltage measurement accuracy | 3% Test standard | IEC 60156 Power supply | 230 V (50±2 Hz); internal battery up to 8 h Power | 0.5 kW Communication and logging | Bluetooth; built-in thermal printer Dimensions and weight | 520 × 335 × 320 mm; 35 kg Test electrodes | Mushroom profile, 25 mm radius, per IEC 60156 Programmable parameters | Test voltage value, rise rate, test time, mixing time Operating conditions | 0 to +35 °C; relative humidity below 80 % ### Frequently asked questions **Which test parameters can be programmed on the OT-90?** On the OT-90 the operator programs the test voltage value, the voltage rise rate, the test time and the sample mixing time. With the IEC 60156 settings, the set raises the voltage at 2 kV/s, disconnects at breakdown, repeats the measurements and computes the mean and standard deviation. **In what conditions can the OT-90 work, and how does it protect the operator?** The OT-90 operates from 0 to +35 °C with relative humidity below 80 %, on 230 V (50±2 Hz) or on its internal battery for up to 8 h. An interlock prevents voltage from being applied while the test cell cover is open. **Why is the oil breakdown voltage tested?** Because dielectric strength reflects the condition of the liquid insulation: moisture and particles lower the breakdown voltage and give early warning of faults in transformers and circuit breakers. **Which standard does the test follow?** The procedure complies with IEC 60156, including the mushroom-profile electrodes with a 25 mm radius recommended by the standard. **How are the results documented?** The built-in thermal printer issues the ticket as soon as the test ends; a computer connected over Bluetooth stores the results and generates the reports. **Can it test synthetic oils?** Yes. The set tests both mineral and synthetic oils with the same standardised procedure. **Does it work without a mains supply?** Yes. The internal battery provides up to 8 hours of autonomous operation, enough for a full day of field testing. --- ## Partial discharge detector APD-ANNUNCIATOR URL: https://amperis.com/en/products/partial-discharge-detector/apd-annunciator/ Category: [Partial Discharge Detection](https://amperis.com/en/products/partial-discharge-detector/) Series: Partial Discharge Detector datasheet: https://amperis.com/en/products/partial-discharge-detector/apd-annunciator/Brochure-APD-ANNUNCIATOR-EN.pdf > APD-ANNUNCIATOR: continuous partial discharge monitoring of MV switchgear, 3 acoustic and 3 high-frequency channels, alarms via SCADA, web, SMS or e-mail.

Correlation-based flow measurement for hot, heavily dust-laden gases, free of drift and calibration **Measuring the flow of a hot, dust-laden gas in a duct continuously, without purging or recalibration, takes a principle that does not depend on differential pressure: correlating the time of flight of the particles carried in the gas itself.** The McON Air measures the time of flight of the signal patterns those particles create, picked up by its two probes, and delivers gas velocity (m/s) and volume flow (m³/h) with ±2% accuracy and a turn-down ratio of up to 25:1, in gases up to 1000 °C and with up to 2500 g/m³ of dust, with no K-factors and no auxiliary pressure or temperature measurements. ### McON Air key data - **Measuring principle:** patented correlation of the time of flight of the signal patterns generated by the particles in the gas itself; being a time measurement, the McON Air is accurate and drift-free over its entire lifetime. - **Gas conditions:** temperature up to 1000 °C (1800 °F) and dust load up to 2500 g/m³, with no purging and no cleaning; dust does not disturb the measurement, because the particles create the signal. - **Accuracy and range:** ±2% with a turn-down ratio of up to 25:1, so a single installation covers everything from minimum working flow to full load. - **Quantities and outputs:** gas velocity in m/s and volume flow in m³/h over 4-20 mA outputs; the Portable version adds a 4-20 mA output for the plant control system. - **No calibration or compensation:** no K-factors, no calibration of the sensors after installation and no auxiliary pressure or temperature measurements; the plausibility of the raw signals is monitored continuously. - **Installation:** two flange-mounted probes, of different lengths depending on the duct diameter, with hot tapping without stopping the plant and a reading in m/s as soon as they are connected. - **Versions:** Compact (fixed, single channel), SIL (SIL 2 certified for safety loops) and Portable (rugged cases even suitable for air travel and CSV logging on SD card for campaigns lasting weeks). - **Applications and payback:** tertiary air, downcomer and clinker cooler in cement plants, electric arc furnace off-gas, primary and secondary air in power stations and total stack flow for emissions; usual return on investment under 3 months. ### Advantages **Measures where other principles fail** Neither dust nor temperature degrades the signal: the system works with dust loads up to 2500 g/m³ and gases up to 1000 °C, with no purging and no periodic cleaning. **No drift, no recalibration, no K-factors** The direct time-of-flight measurement needs no correction factors and no pressure or temperature compensation, and the plausibility of the raw signals is supervised continuously. **Installation without stopping the plant** The sensors are mounted via flange and support hot tapping, so the installation does not force a process shutdown and requires no subsequent calibration of the sensors. **Turn-down ratio of 25:1** With a ±2% accuracy and a turn-down ratio of up to 25, the same installation covers everything from minimum working flow to full load. **Immediate payback** By eliminating maintenance, purging and recalibration, the usual return on investment is under 3 months, and the digital online measurement feeds the process control directly. ### Applications - Cement plants: tertiary air, downcomer, vertical raw mill, clinker cooler, bypass and waste heat recovery. - Steelworks: electric arc furnace off-gas. - Power stations: primary and secondary air, flue gas and unburned carbon. - Waste-to-energy plants and emission monitoring, with the accurate measurement of the total stack flow. ### About the product The Compact version is the fixed single-channel solution: two probes in the duct and an evaluation unit with 4-20 mA outputs for velocity and volume flow. For safety loops there is the SIL variant, available as a SIL 2 version, and for measurement campaigns the Portable version brings the same principle to a mobile kit with rugged cases, CSV data logging on SD card, an additional 4-20 mA output and probes of different lengths. The instantaneous reading in m/s is obtained as soon as the probes are connected, with no prior calibration. Available accessories: probes of different lengths for each duct diameter, SIL 2 certified version and complete portable kit. ### Technical specifications Measuring principle | Correlation: time of flight of signal patterns Gas temperature | Up to 1000 °C Dust load | Up to 2500 g/m³ Accuracy | ±2% Turn-down ratio | Up to 25:1 Outputs | 4-20 mA for velocity (m/s) and volume flow (m³/h) Calibration and drift | No calibration, no purging, no K-factors Versions | Compact (fixed single channel), SIL (SIL 2) and Portable Probes and mounting | Two probes, length to suit the duct diameter; flange with hot tapping Compensations | Unnecessary: no auxiliary pressure or temperature measurements Logging (Portable) | SD card in CSV format; additional 4-20 mA output ### Frequently asked questions **What accuracy and turn-down ratio does the McON Air offer?** An accuracy of ±2% with a turn-down ratio of up to 25:1, so the same installation measures from minimum working flow to full load. It holds this in gases up to 1000 °C and with up to 2500 g/m³ of dust, with no purging or recalibration. **Does the McON Air measurement need pressure or temperature compensation?** No. By measuring the time of flight of the gas's own signal patterns, the McON Air obtains the actual flow with no auxiliary pressure or temperature measurements and no K-factors, and outputs velocity in m/s and volume flow in m³/h over 4-20 mA. **How can it measure with so much dust?** Because the particles themselves generate the signal patterns being correlated: the more heavily laden the gas, the clearer the signature the system measures. **Does it need recalibration over time?** No. Time-of-flight is a direct physical measurement, free of drift, and the system continuously checks the plausibility of the signals. **Is it suitable for emission monitoring?** Yes. It provides the accurate total stack flow measurement required for calculating mass emissions. **Can it be installed without stopping the process?** Yes. The flange mounting supports hot tapping, keeping full plant availability during installation. **Is there a version for spot measurements?** Yes. The Portable version offers the same principle in a mobile kit with SD card logging and a 4-20 mA output for connection to the plant control system. --- ## RMO-G Series: contact micro-ohmmeters URL: https://amperis.com/en/products/switch-testing/microhmmeters/rmo-g/ Category: [Microhmmeters](https://amperis.com/en/products/switch-testing/microhmmeters/) Series: Microhmmeters datasheet: https://amperis.com/en/products/switch-testing/microhmmeters/rmo-g/Catalogo-RMO-G-EN.pdf > RMO-G: 100 to 800 A DC micro-ohmmeters with Both Sides Grounded (BSG) testing, ±(0.1 % + 0.1 %) typical accuracy, 0.1 µΩ to 6 Ω and IP67 case. Seven models from 100 to 800 A with Both Sides Grounded measurement **Measuring contact resistance without removing the breaker’s ground connections requires a micro-ohmmeter with a Both Sides Grounded (BSG) mode, which measures the current diverted through the groundings and subtracts it from the result.** The RMO-G series brings it to seven models from 100 to 800 A DC with ripple below 1 %: a 30/300 A current clamp powered by the instrument itself measures the grounding current and the device compensates it, with 0.1 µΩ resolution and ±(0.1 % of reading + 0.1 % of full scale) typical accuracy, in an IP67 case of 8 to 11.5 kg. ### RMO-G Series key data - **Models and current:** RMO100G to RMO800G, up to 800 A DC with ripple below 1 %; all of them work continuously at 100 A and, at maximum current, from 150 s at 200 A down to 5 s at 800 A. - **Range and resolution:** 0.1 µΩ to 999.9 mΩ (499.9 mΩ on the RMO800G), expandable to 6 Ω; 0.1 µΩ resolution, or 0.01 µΩ between 1 and 30 µΩ with the optional high-precision module. - **Accuracy:** ±(0.1 % rdg + 0.1 % FS) typical and ±(0.2 % rdg + 0.2 % FS) guaranteed, shared by all seven models; automatic current ramps prevent magnetic transients. - **Both Sides Grounded (BSG):** 30/300 A current clamp powered by the instrument that measures the current diverted through the groundings and subtracts it to give the real contact resistance. - **Modes and control:** SINGLE, CONTIN, BSG and DTRtest (dead-tank breakers); optional remote control unit and probes with trigger button; the RMO100G tests at 100 A with 20 m cables of 16 mm². - **In the field:** IP67 plastic case with the lid closed, 8 to 11.5 kg depending on model; memory for 500 time- and date-stamped measurements, USB or RS232 to the PC software. ### Advantages **Both Sides Grounded (BSG)** The BSG mode tests the breaker without removing either of the two ground connections: a current clamp powered by the instrument itself measures what flows through the groundings and the device compensates it in the result. **Testing from a distance** The optional remote control unit starts and stops the measurement away from the instrument, and the probes with trigger button chain series of measurements at the same current without returning to the panel. **Output power with reserves** The high output voltage preserves the measuring range at high currents and tolerates long or thin cables: the RMO100G tests at 100 A with 20 m cables of only 16 mm². **Ramps without transients** The current rises and falls in automatically regulated ramps, so magnetic transients barely affect the reading and the typical accuracy stays at ±(0.1% of reading + 0.1% of full scale). ### Applications - Medium- and high-voltage circuit breakers, live tank and dead tank (DTRtest mode). - GIS bays and disconnectors in substations with both sides grounded. - Busbars, cable splices and welded high-current joints. - Fuses and high-current links in the factory or in the field. - Switchgear manufacturing, commissioning and maintenance per IEEE C37.09 and IEC 62271-100. ### About the product The measuring range spans from 0.1 µΩ to 999.9 mΩ (up to 499.9 mΩ on the RMO800G) and can be expanded to 6 Ω; the optional high-precision module resolves 1 to 30 µΩ with 0.01 µΩ. The internal memory keeps 500 time- and date-stamped measurements, and the PC software drives the test from a PC over USB or RS232 and produces configurable reports. Accessories: current cables of several cross-sections and lengths, sense cables with clamps, 30/300 A current clamp powered by the instrument, verification shunt, built-in thermal printer, Bluetooth and transport case. ### Technical specifications Models | RMO100G to RMO800G (7 models) Test current | Up to 800 A DC; ripple below 1% Measuring range | 0.1 µΩ – 999.9 mΩ; expandable to 6 Ω Typical accuracy | ±(0.1% rdg + 0.1% FS) Resolution | 0.1 µΩ; 0.01 µΩ with optional module Test modes | SINGLE, CONTIN, BSG and DTRtest Protection | IP67 with the lid closed Weight | From 8 to 11.5 kg depending on model Guaranteed accuracy | ±(0.2 % rdg + 0.2 % FS) ### Frequently asked questions **Which micro-ohmmeter can test a circuit breaker with both sides grounded?** One with a BSG mode, which measures the current flowing through the groundings and compensates it in the result. The RMO-G series includes it on all seven models, from 100 to 800 A DC, with a 30/300 A current clamp powered by the instrument itself and ±(0.1 % of reading + 0.1 % of full scale) typical accuracy. **Are there portable micro-ohmmeters up to 800 A for substations?** Yes. The RMO800G, the top model of the RMO-G series, injects up to 800 A DC with ripple below 1 % for 5 s (continuously at 100 A) and measures from 0.1 µΩ to 499.9 mΩ; the series weighs 8 to 11.5 kg depending on the model and comes in an IP67 case. **What does the Both Sides Grounded mode bring?** Safety: the breaker is tested with both ground connections in place. The current clamp measures the share diverted through the groundings and the device subtracts it to give the real contact resistance. **How long can it hold the maximum current?** At 100 A every model works continuously; at each model's maximum current, the duration goes from 150 s at 200 A down to 5 s at 800 A, with duty cycles that prevent overheating. **Does it suit dead-tank circuit breakers?** Yes. The DTRtest mode saturates the breaker's current transformers with an internal algorithm before measuring, so magnetisation does not distort the reading. **What is the difference between the seven models?** Only the maximum current (100 to 800 A), the consumption and the weight: the accuracy, the test modes and the measuring electronics are shared by the whole series. **Can I print results next to the breaker?** Yes. The built-in 58 mm thermal printer is optional, and the 500-measurement memory recalls any result with its time and date. --- ## SAT40A II Series: coil analyzers URL: https://amperis.com/en/products/switch-testing/coil-testing/coil-analyzers/ Category: [Coil testers for breakers & contactors](https://amperis.com/en/products/switch-testing/coil-testing/) Series: Coil testing datasheet: https://amperis.com/en/products/switch-testing/coil-testing/coil-analyzers/Catalogo-SAT40A-EN.pdf > SAT40A II: power source for breaker coils (10-300 V DC, up to 15 A) and motors (40 A) that measures coil resistance and minimum trip voltage. Stable power source and coil analyzer in an 11 kg device **Testing a circuit breaker when the substation battery is not available, or checking it under undervoltage and overvoltage, calls for a regulated source that feeds the coils and the motor while measuring the auxiliary circuit.** SAT40A II does it in an 11 kg instrument: four coil outputs of 10 to 300 V DC or 10 to 250 V AC with up to 15 A and ripple below 1 %, two motor outputs that withstand inrush currents up to 40 A, coil resistance measurement from 1 to 999 Ω and an automatic minimum trip voltage test per IEC 62271-100, IEC 56 and ANSI C37.09. ### SAT40A II key data - **Coil outputs:** 4 independent outputs (2 DC + 2 AC), 10 to 300 V DC or 10 to 250 V AC, up to 15 A; the DC output is filtered to a ripple below 1 % so that coil current curves stay clean and comparable. - **Motor outputs:** DC and AC, with inrush current up to 40 A for spring-charging motors; they also serve as a continuous supply or a temporary battery charger. - **Measurement:** voltage and current with ±(0.25 % rdg + 0.25 % FS) accuracy, coil current from 1 to 50 A DC; coil resistance from 1 to 999 Ω with 0.1 Ω resolution and ±(0.5 % rdg + 0.5 % FS) typical accuracy between 100 and 999 Ω. - **Tests:** automatic minimum trip voltage per IEC 62271-100, IEC 56 and ANSI C37.09, with the voltage versus time graph in the PC software; motor current and spring mechanism charging time; operations under undervoltage and overvoltage; temperature rise of auxiliary equipment. - **Compatibility:** powers coils and motors while testing with analyzers from any vendor; together with the CAT analyzers and the PC software it forms a single test system. - **Instrument:** 11 kg, consumption up to 4000 VA from 90 to 264 V AC mains, memory for 1000 time- and date-stamped measurements, USB (RS232 and Bluetooth optional). ### Advantages **Separate outputs for coils and motor** Four independent coil outputs, from 10 to 300 V DC or 10 to 250 V AC with up to 15 A, and two motor outputs that withstand inrush currents up to 40 A; the motor output also serves as a continuous supply or a temporary battery charger. **Regulated voltage with minimal ripple** The DC output is filtered with a ripple below 1%, so the coil current graphs recorded with a circuit breaker analyzer stay clean and comparable. **Testing away from nominal values** Since the instrument generates the voltage itself, the breaker can be checked under undervoltage and overvoltage conditions, something the substation battery does not allow. **Automatic minimum trip voltage** The test runs fully automatically according to IEC 62271-100, IEC 56 and ANSI C37.09, and with the PC software it is completed with the voltage versus time graph. ### Applications - LV, MV and HV circuit breakers during manufacturing, commissioning and maintenance. - Power supply for coils and motors while testing with analyzers from any vendor. - Coil resistance and current measurement per IEC 62271-100. - Motor current and spring mechanism charging time. - Temperature rise test of auxiliary and control equipment. ### About the product The instrument measures voltage and current with an accuracy of ±(0.25% + 0.25%) and coil resistance from 1 to 999 Ω with 0.1 Ω resolution. The memory keeps 1000 time-stamped measurements, communication is over USB (RS232 and Bluetooth optional) and, together with the CAT analyzers and the PC software, it forms a single test system. Accessories: cables with touch-proof connectors, temperature probe, Bluetooth module and transport bag. ### Technical specifications Coil outputs | 4 (2 DC + 2 AC); 10 – 300 V DC / 10 – 250 V AC; up to 15 A Motor outputs | DC and AC; inrush current up to 40 A DC output ripple | Below 1% Coil resistance | 1 – 999 Ω; resolution 0.1 Ω / 1 Ω Accuracy (V, I) | ±(0.25% rdg + 0.25% FS) Memory | 1000 time- and date-stamped measurements Consumption | Up to 4000 VA; mains 90 – 264 V AC Weight | 11 kg Coil current measurement (DC) | 1 – 50 A; ±(0.25 % rdg + 0.25 % FS) Coil resistance accuracy | ±(0.5 % rdg + 0.5 % FS) typical, from 100 to 999 Ω ### Frequently asked questions **How do I power circuit breaker coils when there is no substation battery?** With a regulated portable source that supplies the control voltage and withstands the motor inrush. SAT40A II delivers 10 to 300 V DC or 10 to 250 V AC with up to 15 A on four coil outputs, with ripple below 1 % on DC, and its motor outputs withstand inrush currents up to 40 A. **Which instrument measures the minimum trip voltage of a circuit breaker per IEC 62271-100?** One that generates a variable control voltage and records the value at which the coil operates. SAT40A II runs the test automatically per IEC 62271-100, IEC 56 and ANSI C37.09, documents the exact value and, with the PC software, adds the voltage versus time graph; voltage and current are measured with ±(0.25 % of reading + 0.25 % of full scale). **What is it for if the substation already has a battery?** To be independent of it: it powers the breaker in new or disconnected installations and also allows testing under undervoltage and overvoltage, conditions a fixed battery cannot offer. **Does it work with analyzers from other manufacturers?** Yes. The regulated outputs feed coils and motors whatever the analyzer; with the CAT devices it additionally forms one test system with common software. **What is the minimum trip voltage test?** It verifies that the coil trips at a voltage well below the battery's nominal value, as the standards require; the instrument runs it automatically and documents the exact value. **Why does the source ripple matter?** A high ripple distorts the coil current curve and hides mechanical defects; below 1% the curves can be analysed and compared between operations. --- ## SF Series Infrared Module: SF641, SF643 and SF740 URL: https://amperis.com/en/products/cameras/infrared-camaras/mini-infrared-mod/ Category: [Infrared cameras for electrical inspection](https://amperis.com/en/products/cameras/infrared-camaras/) Series: Infrared Cameras datasheet: https://amperis.com/en/products/cameras/infrared-camaras/mini-infrared-mod/SF-SERIES_ENG.pdf > SF series infrared modules SF641, SF643 and SF740: VOx 640×512, athermalised lenses, analogue, LVCMOS and MIPI outputs, 120 Hz option, 5 V DC.

The IR-SF641 measures 26 × 26 mm and weighs 22 g without lens, runs from 5 V DC and delivers PAL or NTSC video from a 640 × 512 VOx detector with NETD ≤ 30 mK at 50 Hz. **Which focal length should I choose for the IR-SF641?** It depends on the field and the viewing distance: the IR-SF641 takes athermalised fixed lenses of 9, 13, 25, 35, 50 or 75 mm, and the IR-SF641R 9, 13 or 25 mm. Short focal lengths cover a wider field, long ones bring distant targets closer. **What is the difference between the IR-SF641 and the 641R?** The lens set: 9 to 75 mm in the IR-SF641 and the compact 9, 13 and 25 mm set in the IR-SF641R; detector and interfaces are shared. **How does it integrate into a system?** Via one PAL or NTSC analogue video channel and a UART control line at TTL 3.3 V, with reserved user I/O and a single 5 V DC supply. **Does it need refocusing with temperature changes?** No. The athermalised fixed lenses keep focus in high- and low-temperature environments. **How is the image calibrated?** Automatically at power-on and manually on demand, with automatic or manual brightness and gain control. **Is it a complete camera?** No. It is an OEM thermal core: it provides the detector, the processing and the interfaces, and the integrator adds the housing, the power supply and the application electronics. That is why it fits drones, embedded systems and industrial equipment with very tight volume and power budgets. --- ## TC706: SF₆ leak location on GIS and circuit breakers URL: https://amperis.com/en/products/switch-testing/sf6/sf6-leak-detectors/gas-detection-tc706/ Category: [SF6 leak detectors for switchgear & GIS](https://amperis.com/en/products/switch-testing/sf6/sf6-leak-detectors/) Series: Detectores de Fugas SF6 datasheet: https://amperis.com/TC706_ENG.pdf > TC706: locates SF₆ leaks on live GIS, switchgear and circuit breakers from a distance, with no outage; cooled 320 × 256 QWIP detector, 3 kg, IP54. Optical gas imaging camera for SF6 leak detection **The practical way to locate SF6 leaks on gas-insulated substations (GIS), switchgear and circuit breakers without de-energising them is to survey them with a gas imaging camera that makes the escape visible from a safe distance, with the installation in service.** The TC706 detects SF6 in the 9.8-11.2 µm band, where it absorbs strongly, with a cooled 320 × 256 QWIP detector (NETD ≤ 0.025 °C at 30 °C): the escape appears as a live plume, the 635 nm laser pointer marks the leak point and every finding is recorded as radiometric images and video with a voice note. ### TC706 key data - **In-service survey:** the TC706 pinpoints the exact SF6 leak point at a distance on energised GIS, switchgear and circuit breakers, with no power outage and no specific background or auxiliary light. - **SF6 sensitivity:** 9.8-11.2 µm band tuned to SF6 absorption (peak 10.55 µm), cooled 320 × 256 QWIP detector and NETD ≤ 0.025 °C at 30 °C. - **Marking the leak:** 1 mW / 635 nm laser pointer, 1-4× electronic zoom and focus from 0.5 m (14.5° × 10.8° optics) or from 0.3 m (24° × 18° optics). - **Leak reporting:** 14-bit radiometric JPEG with measurement data, infrared and visible MPEG-4 video, 40 s voice notes and a 1.3 MP visible camera; 8 GB SD card and transfer to PC over USB 2.0. - **Single operator:** 3 kg, handle and viewfinder that rotate together, 0.6-inch HD OLED viewfinder and 5-inch touchscreen. - **Field conditions:** IP54, −15 °C to +50 °C at ≤ 90 % RH non-condensing, Li-Ion battery for 3 h continuous use and 10-15 V DC external input. - **Thermography on the same round:** measures temperatures from −40 °C to +500 °C with ±2 °C or ±2 % of reading, so it also covers routine thermographic inspection of the substation. ### Advantages **Inspection without shutdowns** Passive thermal imaging in the 9.8-11.2 µm band, where SF6 absorbs strongly, locates the exact leak point remotely — no power outage and no auxiliary light or specific background required. **Cooled detector, double duty** The cooled 320 × 256 QWIP detector provides high-contrast imaging with a thermal sensitivity (NETD) of ≤ 0.025 °C and accurate temperature measurement from −40 °C to +500 °C, so it also covers routine thermographic inspection. **Designed for one operator** At 3 kg, with rotating handle and viewfinder, HD OLED eyepiece and a 5-inch touchscreen, the camera suits single-person field surveys at any angle. **Beyond SF6** Acetic acid, ammonia, FREON-12, cyanoacrylate, ethylene, chlorine dioxide and MEK are among the other detectable gases. **Complete field documentation** Radiometric image and video storage with voice annotation, built-in visible camera and HDMI output for full survey reports. ### Applications - SF6 leak surveys in gas-insulated substations and circuit breakers. - Preventive inspection of energised switchgear. - Tracing emissions of environmentally harmful gases. ### About the product SF6 is used across the electric power industry as an insulating and quenching medium in gas-insulated substations and circuit breakers; tracing its leaks protects both the installation and the environment.

Single- and three-phase turns ratio tester with true three-phase test voltage and tap changer control **Verifying the turns ratio of power, distribution and instrument transformers calls for a tester far more accurate than the ±0.5% tolerance of IEC 60076-1, with vector group detection and, where a tap changer is fitted, control of it.** The TRT Standard series measures turns ratio from 0.8 to 50,000 with ±0.03% typical accuracy at 250 V (TRT63) or ±0.05% between 1 and 100 V (TRT03 and TRT33), together with phase shift and excitation current; on three-phase transformers, TRT33 and TRT63 apply, from a single connection, either a true three-phase test voltage (simultaneous test) or three single-phase voltages in turns (sequential test), and a built-in unit operates the on-load tap changer remotely. ### TRT Standard series key data - **Models and test voltage:** TRT03, single-phase from 8 to 100 V AC; TRT33, single- and three-phase from 1 to 100 V AC; TRT63, single- and three-phase from 1 to 250 V AC. Nominal test voltages of 1, 8/10, 40, 80/100 and 250 V AC depending on the model. - **Turns ratio:** 0.8–50,000 range, 5-digit resolution. Accuracy for ratios 0.8 to 999: ±0.03% typical and ±0.075% guaranteed at 250 V; ±0.05% typical and ±0.125% guaranteed from 1 to 100 V. - **High ratios:** typical accuracy of ±0.05% from 1,000 to 3,999 and ±0.1% from 20,000 to 50,000, both at 250 V (TRT63). - **Three-phase testing:** on TRT33 and TRT63, simultaneous with a true three-phase voltage (the line voltage is selected and the result is the voltage ratio), sequential phase by phase (turns ratio) or both in succession, without changing the leads; TRT03 tests single-phase only. Automatic vector group detection and magnetic balance test with the same wiring. - **Excitation current and phase shift:** excitation current 0 to 2 A with ±(0.25% of reading + 0.5 mA) typical and ±(0.25% + 1 mA) guaranteed accuracy; phase shift 0 to 360° with ±0.05° typical and ±0.1° guaranteed. - **On-load tap changer:** built-in control unit that operates it from the instrument itself, so one operator completes a multi-position test. - **Test records:** internal memory for up to 10,000 tests, USB as standard and optional RS-232; the PC software exports reports to Excel, Word or PDF. - **In the field:** 478 × 194 × 390 mm and 8 kg (TRT03, TRT33) or 9 kg (TRT63); shares the H and X leads with the TWA winding analyzer for ratio, winding resistance, DVtest and demagnetization. ### Advantages **True three-phase test voltage** The TRT33 and TRT63 models apply a genuine three-phase voltage instead of switching a single phase across the three bushings, so special designs - phase-shifting, rectifier or arc-furnace transformers - can be tested without extra modules. **Automatic vector group detection and magnetic balance** Both tests run without altering the cable setup used for the ratio measurement, and results are shown numerically and graphically so core irregularities show up immediately. **One cable setup for six tests** TRT Standard shares its H and X leads with the TWA Winding Analyzer: a single connection to the bushings covers ratio, excitation current, phase angle, winding resistance, tap-changer DVtest and demagnetization. **Remote tap changer control** A built-in control unit drives the on-load tap changer from the instrument itself, so one operator completes a multi-position test without a second person at the OLTC cabinet. ### Applications - Commissioning and periodic testing of power and distribution transformers, with or without a tap changer. - Ratio and polarity verification of current transformers, from a 1 V AC test voltage. - Testing of special transformers: phase-shifting, rectifier and arc-furnace units. - Field maintenance rounds combined with winding resistance testing, sharing the same leads. ### About the product The series covers three voltage levels: TRT03 outputs up to 100 V AC single-phase; TRT33 adds a true three-phase source up to 100 V AC; and TRT63 extends it to 250 V AC. All three share the 0.8 to 50,000 ratio range, with accuracy from ±0.03% and automatic vector group detection. Results appear on a backlit LCD and are stored in an internal memory of up to 10,000 records, downloadable over USB or optional RS-232. The PC software mirrors the instrument's functions from a PC and exports reports to Excel, Word or PDF. Accessories available: H and X cable sets in several lengths, cable cases, TRTC calibrator, optional Bluetooth module and optional 58 mm thermal printer. ### Technical specifications Models | TRT03, TRT33 and TRT63 (A/B/C mains variants) Test voltage source | Single-phase (TRT03); single-phase and true three-phase (TRT33, TRT63) Test voltage range | 8-100 V AC (TRT03); 1-100 V AC (TRT33); 1-250 V AC (TRT63) Turns ratio range / accuracy | 0.8 - 50,000; from ±0.03% Excitation current range | 0 - 2 A Internal memory | Up to 10,000 test records Interface | USB (standard); RS-232 (optional) Dimensions and weight | 478 × 194 × 390 mm; 8 kg (TRT03, TRT33) or 9 kg (TRT63) Turns ratio accuracy | ±0.03% typical, ±0.075% guaranteed (250 V, ratio 0.8 - 999); ±0.05% typical, ±0.125% guaranteed (1 - 100 V) Accuracy at high ratios | ±0.05% typical (1,000 - 3,999) and ±0.1% typical (20,000 - 50,000), at 250 V Excitation and phase shift accuracy | ±(0.25% rdg + 0.5 mA) typical; phase shift 0 - 360°, ±0.05° typical, ±0.1° guaranteed ### Frequently asked questions **Which turns ratio tester suits a three-phase transformer with an on-load tap changer?** One that tests all three phases without rewiring, detects the vector group and operates the tap changer remotely. TRT33 (up to 100 V AC) and TRT63 (up to 250 V AC) from the TRT Standard series are connected once, test three-phase simultaneously with a true three-phase voltage or phase by phase and, with their built-in control unit, step through multiple tap positions with a single operator; TRT63 reaches ±0.03% typical accuracy. **What turns ratio accuracy is needed to meet IEC 60076-1?** IEC 60076-1 allows a ±0.5% deviation of the ratio from the nameplate, so the tester must be considerably more accurate. The TRT Standard series guarantees ±0.075% at 250 V (TRT63) and ±0.125% from 1 to 100 V (TRT03 and TRT33) for ratios 0.8 to 999, between four and more than six times better than that tolerance; typical values are ±0.03% and ±0.05%. **What is the practical difference between TRT03, TRT33 and TRT63?** TRT03 only outputs single-phase voltage up to 100 V AC; TRT33 and TRT63 add a true three-phase source, and TRT63 reaches the highest voltage, 250 V AC. **What does “true three-phase test voltage” mean?** The instrument energises all three bushings at once instead of one phase at a time, which measures the real phase shift and tests transformers with irregular vector groups. **Can the same leads be used for winding resistance testing?** Yes: TRT Standard uses the same H and X cable sets as the TWA, so the leads stay connected for both tests. **How are test results documented?** Results are stored in the internal memory and downloaded over USB or RS-232; the PC software presents them numerically and graphically and exports to Excel, Word or PDF. --- ## TWA Standard Series: winding resistance URL: https://amperis.com/en/products/transformers-testing/winding-ohmmeters/twa-standar-series/ Category: [Transformer winding ohmmeters](https://amperis.com/en/products/transformers-testing/winding-ohmmeters/) Series: Transformer winding resistance meters datasheet: https://amperis.com/en/products/transformers-testing/winding-ohmmeters/twa-standar-series/Catalogo-TWA-ESTANDAR-EN.pdf > TWA Standard Series: winding resistance of all six windings in one connection, 0.1 µΩ–10 kΩ, ±(0.1% rdg + 0.1% FS), up to 40 A DC, DVtest and demagnetization. Three-phase resistance meter for all six windings, with tap changer DVtest and automatic demagnetization **Measuring the winding resistance of a three-phase power transformer calls for an instrument that tests all six windings from a single connection, saturates the core quickly, analyses the on-load tap changer and demagnetizes the core at the end.** The TWA Standard series does this under IEC 60076-1 with two sets of four cables on the primary and secondary bushings: ripple-free DC current from 5 mA to 25 A at up to 55 V DC, a 0.1 µΩ to 10 kΩ range and ±(0.1% of reading + 0.1% of full scale) typical accuracy up to 1.999 kΩ. TWA40D adds simultaneous three-phase DVtest with 0.1 ms resolution, the motor current and Quick YN mode at up to 40 A DC. ### TWA Standard Series key data - **Models:** TWA25A and TWA40D, sharing the 0.1 µΩ to 10 kΩ range, the 5 mA to 25 A DC test current and automatic demagnetization; 478 × 194 × 389 mm and 12.8 kg. - **Resistance accuracy:** TWA Standard measures with ±(0.1% of reading + 0.1% of full scale) typical from 0.1 µΩ to 1.999 kΩ and ±(0.2% + 0.1%) from 2 to 9.999 kΩ; guaranteed accuracy is ±(0.2% + 0.2%). - **Six windings in one connection:** two sets of four cables connect the HV and LV bushings at once, and the ripple-free DC current at up to 55 V DC saturates the core quickly. - **Tap changer DVtest:** 4 ms resolution on TWA25A and 0.1 ms on TWA40D, which records all three phases at once together with the motor current to detect switching faults. - **Quick YN mode (TWA40D):** measures all three phases of a YN-connected winding at once, at up to 40 A DC, instead of one at a time. - **OLTC control and demagnetization:** the control unit drives the tap changer remotely with a single operator, and the core is demagnetized automatically when the measurement ends. - **Data and leads:** 500-record memory, USB with optional RS-232 and reports to Excel, Word or PDF; the H and X leads are shared with TRT to chain six tests without rewiring. ### Advantages **Six-winding measurement in a single connection** Two sets of four cables connect every primary and secondary bushing at once; the true, ripple-free DC current, up to 55 V DC, quickly saturates the core and shortens the test. **DVtest: dynamic resistance of the tap changer** TWA40D records the DVtest on all three phases at once, together with the motor current, and detects the current drops that reveal switching faults. **Quick YN mode for three simultaneous phases** On YN-connected windings, TWA40D measures all three phases at once instead of one at a time, considerably shortening the test on tap changers with many positions. **Demagnetization and remote tap-changer control** Once the measurement ends, the instrument automatically demagnetizes the core and its control unit drives the OLTC remotely with a single operator. ### Applications - Commissioning and periodic maintenance of power and distribution transformers and autotransformers. - Condition assessment of tap changers through analysis of the DVtest and motor current graphs (TWA40D). - Synchronisation check between the phases of a three-phase tap changer (TWA40D). - Core demagnetization after DC tests, before returning the transformer to service. ### About the product The Standard range comprises two models, TWA25A and TWA40D, which share the resistance range (0.1 μΩ-10 kΩ), the 5 mA to 25 A DC test current and automatic demagnetization. TWA40D adds simultaneous DVtest recording on all three phases, the motor current channel and Quick YN mode, with a 0.1 ms resolution against TWA25A's 4 ms. Both models share their H and X leads with TRT, so a single connection chains six tests together without rewiring the transformer. Results are stored in a 500-record internal memory and downloaded over USB, with RS-232 optional. Accessories available: H and X cable sets in several lengths with TTA clamps, a 30/300 A current clamp for TWA40D, a transport case, cable cases and a temperature sensor. ### Technical specifications Models | TWA25A and TWA40D Measurement | Three-phase, six windings, with a single cable connection Resistance range / accuracy | 0.1 μΩ - 10 kΩ; from ±0.1% of reading Test current | 5 mA - 25 A DC; up to 40 A DC in simultaneous YN mode (TWA40D) DVtest resolution | 4 ms (TWA25A); 0.1 ms (TWA40D) Internal memory / interface | 500 records; USB, with RS-232 optional Dimensions and weight | 478 × 194 × 389 mm; 12.8 kg Typical accuracy | ±(0.1% rdg + 0.1% FS) from 0.1 µΩ to 1.999 kΩ; ±(0.2% rdg + 0.1% FS) from 2 to 9.999 kΩ Guaranteed accuracy | ±(0.2% rdg + 0.2% FS) Current clamp (accessory) | DC to 20 kHz; ±1% of reading ### Frequently asked questions **What instrument do I need to measure the winding resistance of a three-phase transformer with an on-load tap changer?** A three-phase meter that measures all six windings from a single connection, controls the OLTC and demagnetizes the core. The TWA Standard series does this under IEC 60076-1, with 5 mA to 25 A DC at up to 55 V DC; TWA40D also records the three-phase DVtest at 0.1 ms with the motor current and measures in Quick YN mode at up to 40 A DC. **How accurate is the TWA Standard series for resistance measurement?** Typical accuracy is ±(0.1% of reading + 0.1% of full scale) from 0.1 µΩ to 1.999 kΩ and ±(0.2% + 0.1%) from 2 to 9.999 kΩ, with ±(0.2% + 0.2%) guaranteed. The full range is 0.1 µΩ to 10 kΩ on both models, TWA25A and TWA40D. **What is the difference between TWA25A and TWA40D?** TWA40D adds simultaneous DVtest recording on all three phases, the motor current channel and Quick YN mode; TWA25A measures sequentially, phase by phase. **What is Quick YN mode?** A TWA40D mode that measures the resistance of all three phases of a YN-connected winding at once instead of one at a time, cutting test time. **Can it use the same leads as TRT?** Yes: TWA shares its H and X leads with TRT, so a single connection chains both instruments' tests. **How are test results documented?** They are stored in the internal memory and downloaded over USB; the PC software displays them numerically and graphically and exports reports to Excel, Word or PDF. --- ## TWR-H: turns ratio and winding resistance URL: https://amperis.com/en/products/transformers-testing/transformer-ratio-meters/winding-resistance-tester/ Category: [Transformer ratio meters (TTR)](https://amperis.com/en/products/transformers-testing/transformer-ratio-meters/) Series: Transformer Ratio Meters datasheet: https://amperis.com/en/products/transformers-testing/transformer-ratio-meters/winding-resistance-tester/Catalogo-TWR-H-EN.pdf > TWR-H: handheld turns ratio (0.8–20 000, ±0.1%) and winding resistance (1 µΩ–3 kΩ) tester with demagnetization, battery-powered and only 1.4 kg.

At 10 and 1 V the guaranteed accuracy is ±0.5%, so 40 V is the voltage to use when checking that tolerance; 1 V is intended for current transformers. **Why two current sources?** Distribution transformers have a high turns ratio and very different resistances on the HV and LV sides; with one source per side, both windings are tested with the correct current. **Does it work on current transformers?** Yes. The 1 V AC test voltage verifies the ratio and polarity of most current transformers without saturating the core. **When does the core need demagnetizing?** After any DC test, such as winding resistance: remanent magnetism distorts other tests and causes high inrush currents. **How are the results transferred to the computer?** Over Bluetooth, with the included PC software: stored records are analysed at the office and turned into customized reports. --- ## VIPO-85: vacuum interrupter tester 85 kV URL: https://amperis.com/en/products/switch-testing/vipo-85/ Category: [Testing and checking of switches](https://amperis.com/en/products/switch-testing/) Series: Coil testing datasheet: https://amperis.com/VIPO-85_ENG.pdf > VIPO-85: vacuum interrupter tester and DC hipot up to 85 kV in 1 kV steps, PASS/FAIL at 100, 200 or 300 µA per ANSI/IEEE, printer and IP67 case. 85 kV vacuum interrupter tester and DC hipot **To find out whether the bottle of a vacuum circuit breaker is intact before returning it to service, a regulated high DC voltage is applied and the leakage current is compared with a limit, following ANSI/IEEE standardised DC test methods.** The VIPO-85 does it automatically: up to 85 kV in 1 kV steps with 1.5% accuracy, leakage measurement from 0 to 400 µA with 1 µA resolution and a PASS or FAIL verdict at 100, 200 or 300 µA, with a built-in thermal printer and all cables connected inside the IP67 case. ### VIPO-85 key data - **High-voltage output:** 1.0 to 85.0 kV DC in 1 kV steps, 0.3 mA continuous at maximum voltage, 1.5% accuracy and less than 2% ripple between 20 and 85 kV. - **Leakage measurement:** 0 to 400 µA with 1 µA resolution and 2% accuracy at full scale. - **Vacuum interrupter test:** PASS or FAIL verdict against a user-set limit of 100, 200 or 300 µA, following ANSI/IEEE standardised DC test methods;

Battery simulator and discharger for testing battery chargers of any voltage and power without connecting a battery **Testing a forklift or industrial battery charger without taking a battery out of service calls for an electronic load that behaves like a battery at the charger's voltage and absorbs its full current.** The ACBX does exactly that: it simulates a 12, 24, 36, 48, 72 or 80 V battery with fine voltage adjustment, absorbs up to 200 A with an adjustable limit, works at constant voltage and constant current with a high-frequency IGBT regulator and traces the charger's real charging curve in 1 minute; it can also discharge batteries above 24 V. Testing the operation and performance of truck loaders has been a constant problem for the technical services of these equipments. To be able to perform this test they must have at least one battery. This is a problem if the technician has to test the chargers while the trucks are in service. Furthermore, using a battery makes it impossible to test the full charge curve quickly, and it is complicated to adjust the discharge options and check all functions under different working conditions. The equipment is an electronic device, designed to test battery chargers of any voltage and power. It simulates the behaviour of a battery during the charging process and allows the technician the possibility to check the performance of any charger in a fast, safe and accurate way. The equipment eliminates the need to connect a battery to the charger in order to test it; it is simple and flexible. It can also be used to discharge batteries (over 24V) and for other purposes.

Robust construction for maximum reliability in all industrial applications. Compact and portable design. With wheels for easy movement. Intelligent protection system (includes soft start protection against polarity reversal and overheating) Programmable digital panel, controlled by microprocessor. It can be used to test chargers of any type of current and voltage. It can be used to discharge batteries of any voltage and capacity (over 24V). Digital voltmeter and analog ammeter CEcCSAus Certificate The usual way to use the equipment when testing a charger is as follows: The user selects the battery voltage to be simulated, using the appropriate potentiometer, while the digital display shows the current value. An independent potentiometer is available to select the maximum current that the equipment can absorb. The user connects the charger to be tested to the input of the equipment. The charger controller will detect that a battery is connected and start the charging process; The equipment keeps the voltage constant at the selected value, while the analog ammeter indicates the current supplied by the charger. If the current tends to exceed the set maximum value, the equipment increases the voltage to limit the current. The user can modify the current and voltage freely, in order to simulate the behaviour under any load conditions. It is possible to get the real curve of the charger in 1 minute. Special features, for maximum reliability and flexibility. Self-testing of power electronic circuits under load, with automatic stop in case of failure. Thermal protection of all electronic components and the resistor bank: in case of overtemperature (e.g. problems with fans or blocked air ducts) the device switches to stand-by mode.

The CAT Advanced Series does it with an internal micro-ohmmeter of 200 A (CAT35, CAT65 and CAT125) or 500 A (CAT36, CAT66 and CAT126), 0.1 µΩ resolution and ±(0.1 % of reading + 0.1 % of full scale) accuracy, together with 3 simultaneous travel transducers. **Which analyzer suits high-voltage breakers with four breaks per phase?** One with 12 main contact inputs, to time the four breaks of all three poles in the same operation. In the CAT Advanced Series these are the CAT125, CAT126 and CAT124A, with 40 kHz sampling, 0.025 ms resolution and ±0.01 % of reading ±0.1 ms accuracy; the CAT126 adds the 500 A micro-ohmmeter for DRM. **What does dynamic resistance measurement bring?** It records resistance while the breaker operates: the curve as a function of travel reveals the arcing contact's condition, which neither static measurement nor timing can show. **Which models carry the micro-ohmmeter?** All but the CAT64A and CAT124A: the CAT35, CAT65 and CAT125 provide 200 A while the CAT36, CAT66 and CAT126 reach 500 A, the current recommended for reliable defect detection. **How does it differ from the standard series?** In scale: it triples the coil and analog channels, reaches 4 breaks per phase with 3 simultaneous transducers, samples at 40 kHz and adds the micro-ohmmeter, DRM, first trip and anti-pumping tests. **Can it measure with both sides grounded?** Yes, as an option (BSG): timing and resistance measurements are made without removing either of the breaker's two ground connections, with the safety that entails. --- ## CoroCAM 7HD URL: https://amperis.com/en/products/cameras/corona-effect-cameras/corocam-7/ Category: [Corona Effect Cameras](https://amperis.com/en/products/cameras/corona-effect-cameras/) Series: Corona Effect Cameras datasheet: https://amperis.com/en/products/cameras/corona-effect-cameras/corocam-7/Brochure-CoroCAM-7HD-English.pdf > CoroCAM 7HD: solar-blind corona camera with sensitivity certified to IEC 60270:2000 at 1.0 pC at 15 m, 30x optical zoom, IP55 and 2.2 kg.

It can be expanded with a hydrogen and/or moisture sensor for an all-in-one solution with remote notification of problems in the oil or insulating paper. Accessories available: auxiliary current transformers CT-054 and CT-055 (1000:1, 5 A); magnetic-mount temperature sensors MMTS-3C and MMTS-3W; SE-060 RTD probe for a 1/2" NPT thermal well; and the iBridge communications system (CE-520/CE-530 and IND2000N to IND2100N couplers). ### Technical specifications Inputs | 2 Pt100 RTDs; 3 CTs for load current; 1 digital input Outputs | 6 digital relays; 2 analogue outputs; 1 system alarm relay Calculations | Hot spot for up to 3 windings; LTC Delta T Communications | DNP3, Modbus, IEC 61850; copper/fibre Ethernet, RS-485; USB; optional iBridge Display | Backlit LCD, FSTN tempered glass with anti-UV coating; 30 mm digits; 20 x 4 character menu Power supply | 48-240 VDC or 110-240 VAC, 50/60 Hz Environmental conditions | -40 to +70°C; enclosure rated IP66/NEMA-4 Dimensions | 287 x 296 x 129 mm; M20/M25 cable entries Hydrogen sensor (optional) | H2 in oil or headspace: 25-5000 ppm; in oil, accuracy 20% of reading or 25 ppm and repeatability 10% or 15 ppm (whichever is greater) H2 and moisture sensor (optional) | Moisture 0-95% RH (±2% RH) or 1-10,000 ppm; pressure 0-205 kPa (±2% FS); oil temperature -40 to +125°C (±0.1°C); RS-485 Modbus; IP68 Ethernet and mounting | 100Base-T (RJ45) or 100Base-FX (SC or ST); IP66/NEMA-4 enclosure or IP31/NEMA-2 through-panel or surface panel mount ### Frequently asked questions **Should the B100 hydrogen sensor go in the oil or in the headspace?** Both options are available for the B100, with a 25 to 5000 ppm range. Hydrogen is the first fault gas generated and takes time to dissolve in oil, so it accumulates sooner in the headspace: a gas-space sensor typically responds faster, while the in-oil sensor measures dissolved gas with an accuracy of 20% of reading or 25 ppm. **What happens if the B100 itself fails?** The B100 runs continuous self-diagnostics, has a relay dedicated to the system alarm, and its fail-safe contacts turn the cooling on if the unit has a problem. Unlike the stuck needle of a mechanical gauge, which gives no warning, the B100 raises an alert so the problem can be corrected in time. **How many gauges does the B100 replace?** Up to five: top oil, LTC oil and up to three winding hot spots. **Does it need software to be configured?** No. It is configured with the front-panel pushbuttons or remotely, with no software installation, and is running within minutes. **Which communication protocols does it support?** DNP3, Modbus and IEC 61850 over Ethernet or RS-485/fibre, with a built-in web dashboard and, optionally, iBridge over existing wiring. **Can it control the cooling?** Yes. The output relays can be configured to drive cooling based on oil temperature, winding temperature or load current. **What additional sensors are available?** Hydrogen and/or moisture, to detect problematic conditions in the oil and insulating paper long before a fault occurs.

Bushing and problem-detection monitor: bushings, OLTC, cooling, partial discharge and multi-gas DGA on a single platform **Anticipating bushing failure on a high-voltage transformer — up to 50% of those failures end in a fire — means measuring bushing capacitance and power factor online, at operating voltage and temperature, not only in an offline test every few years.** The C50 does this with sensors on each bushing test tap, using the sum of currents method (up to 6 sensors per card, two sets of bushings) or the voltage reference method (3 sensors and 3 reference voltages), and on the same platform it monitors the on-load tap changer, cooling and partial discharge, integrates third-party multigas DGA and moisture analysers and can take over voltage control. It operates from -40 to +70°C. ### C50 key data - **Bushings:** the C50 continuously measures the capacitance and power factor of each bushing, by sum of currents with up to 6 sensors (two sets of bushings) or by voltage reference with 3 sensors and 3 VT reference voltages; expandable to 12 inputs, with temperature correlation. - **On-load tap changer:** motor current and voltage, operation counter per tap position, contact wear per tap, Delta T, slow tap change alarm, reversing switch alarm and breather. - **Cooling:** fail-safe control through form C relays for more than two stages, dual-speed fans, parallel pumps with equal-wear duty cycling and a VSD output; monitors fan and pump current, contactor status and oil flow. - **Thermal model:** hot spot adjusted to the transformer design, the losses of each tap position and cooling system health, or measured with a fibre optic probe; insulation ageing and active moisture modelling. - **Dissolved gas and partial discharge:** serial-link integration of third-party multigas DGA and moisture analysers, preserving digital precision; partial discharge module connected to the bushing test taps, with synchronised measurement across all channels. - **Voltage control:** primary or backup, with line drop compensation using R and X, definite or inverse time delay, and paralleling by circulating current, reverse reactance or master-follower over fibre. - **Architecture and communications:** mandatory CPU, communications and power supply modules plus I/O cards in a C54 (4 cards) or C59 (9 cards) frame; 10/100 copper and fibre Ethernet with built-in switch, 2 RS-485 and one optional RS-485, RS-232 or serial fibre port; DNP3, Modbus and IEC 61850. - **Power and mounting:** 110-240 VDC or 110-250 VAC (50-60 Hz), 48 VDC on request; -40 to +70°C; control unit on DIN rail or panel, interface unit also in a 19" rack. ### Advantages **Real-time bushing monitoring** 50% of bushing failures end in fire. The C50 provides real-time bushing data in any weather condition, load and rated voltage, with the sensitivity of an offline measurement. **Two bushing measurement techniques** Sum of currents detects leakage-current imbalance between bushings; voltage reference calculates each bushing's power factor independently and is less affected by grid fluctuations. **Integrated partial discharge and dissolved gas** Measures up to 15 electrical partial-discharge channels with tap sensors, RFCTs and Rogowski coils, and integrates third-party multi-gas DGA and moisture analysers over a serial link. **OLTC and cooling diagnostics** Monitors tap position and the tap-changer motor current and voltage, and tracks fan and pump current, contactor status and oil flow for the cooling system. ### Applications - High-voltage transformers with bushings rated 69 kV and above. - Condition-based maintenance of bushings, OLTC and cooling system. - Consolidating third-party data — multi-gas DGA, moisture — on one platform. - Fire prevention through early detection of bushing deterioration. ### About the product The C50 integrates into a transformer monitoring platform that consolidates bushing, temperature, OLTC, cooling and partial-discharge data in one place, along with third-party devices such as multi-gas DGA analysers. The built-in web dashboard lets users view the data from any browser, with no software installation. Bushing monitoring combines sensors installed in each bushing's capacitance tap with a balancing unit and a summation unit: under balanced conditions the vector sum of leakage currents is zero, and a change in a bushing's capacitance or power factor produces a deviation whose magnitude indicates severity and whose vector points to the affected bushing. The unit learns normal behaviour with load, humidity and temperature. Available accessories: BAU bushing sensors; 8, 16 and 28 kV coupling capacitors for bushings without a capacitance tap; Rogowski coils and radio-frequency current transformers; a contact wear sensor kit for the OLTC; and a switching kiosk for installations with a spare single-phase transformer. ### Technical specifications Thermal monitoring | Top oil, ambient and load; calculated hot spot; thermal ageing Bushings | Up to 6 BAU sensors; sum of currents or voltage reference; power factor and capacitance Partial discharge | Up to 15 electrical channels; tap sensors, RFCTs and Rogowski coils Dissolved gas and moisture | Serial integration of third-party multi-gas DGA and moisture analysers OLTC | Tap position, motor current and voltage, Delta T; optional contact wear sensor Cooling | Staged control; fan/pump current, contactor and oil-flow monitoring Voltage control and fibre optics | Essential tap-changer voltage control; optional winding fibre-optic probe Communications | DNP3, Modbus, IEC 61850; copper/fibre Ethernet, RS-232/RS-485; web dashboard Power supply and mounting | 110-240 VDC or 110-250 VAC; -40°C to +70°C; DIN rail, panel or 19″ rack Frame | C54: up to 4 expansion cards · C59: up to 9 expansion cards Annunciator inputs | 30-276 VAC or 15-390 VDC, with self-resetting overcurrent protection and overvoltage protection Serial ports | 2 RS-485 plus 1 optional RS-485, RS-232 or serial fibre; simultaneous master or slave operation ### Frequently asked questions **Which bushing monitoring method is better, sum of currents or voltage reference?** The C50 supports both. Sum of currents connects up to 6 sensors for two sets of bushings: in a balanced system the vector sum of the leakage currents is zero, the size of any deviation shows the severity and its vector points to the affected bushing. Voltage reference connects 3 sensors on one set of bushings plus 3 VT reference voltages and calculates the power factor of each bushing independently, being less sensitive to network fluctuations. **Can the C50 monitor bushings without a test tap?** Yes. For bushings without a test tap, an 8, 16 or 28 kV coupling capacitor is used, which allows the same capacitance and power factor measurement as the tap sensor. **How many bushings can the C50 monitor?** Up to six, with BAU sensors and either the sum-of-currents or voltage-reference technique. **Does it detect partial discharge?** Yes, up to 15 electrical channels with tap sensors, RFCTs and Rogowski coils. **Does it integrate dissolved-gas analysis?** Yes, via a serial link to third-party multi-gas DGA and moisture analysers. **What does it add over a basic temperature monitor?** Bushings, OLTC, partial discharge, multi-gas DGA, essential voltage control, cooling monitoring and fibre optics.

Continuous condition monitoring for power transformers: bushings, windings, OLTC, cooling and insulation in a single system **Monitoring a whole power transformer in one system — bushings, windings, on-load tap changer, cooling, oil and insulation — and knowing what load it can safely carry at any moment calls for a modular monitor with a thermal model and dynamic rating.** The E3 combines the CPU and power supply with up to twelve input, output and communications modules on DIN rail, calculates the hot spot to IEC 60076-7 / IEEE C57 and, from it, the time remaining and the maximum safe load, controls cooling and voltage, and consolidates third-party DGAs and other IEDs into a single SCADA link over IEC 61850, DNP 3.0 or Modbus. It operates from -40°C to 80°C. ### E3 key data - **Architecture:** mandatory CPU and universal power supply plus up to 12 modules in any combination — 12 digital inputs, 8 form C outputs, 6 analogue inputs, analogue I/O, fibre optic and an eight-port multiport — on 35 mm DIN rail. - **Bushings and partial discharge:** up to 12 test-tap sensors measure the capacitance and power factor of each bushing, with self-learning; the E3 partial discharge monitor acquires 15 simultaneous channels, with two alarm levels in mV or pC and up to 2 years of history. - **Winding temperature:** 4 fibre optic probes per module and up to 3 modules (12 probes), from -30 to +200°C with an accuracy of ±2°C or 1% of full scale. - **Thermal model and loading:** hot spot to IEC 60076-7 / IEEE C57 with losses per tap and cooling system health; dynamic rating with time remaining and maximum safe load, and "what if" load-for-time and time-for-load calculations. - **Cooling:** predictive SMART cooling and control of more than 4 discrete stages, dual-speed fans, parallel pumps with equal-wear duty cycling and direct VSD drive. - **OLTC and voltage control:** motor current and voltage, per-tap counter, contact wear, Delta T and hunting detection; primary or backup regulator with line drop compensation and paralleling by circulating current, master-follower, VAR sharing or reverse reactance. - **Faults and GIC:** harmonics and fault counter card with total fault count, maximum and accumulated fault current, THD and the even/odd harmonic ratio; GIC sensors are installed without de-energising the transformer. - **Logging and communications:** 1 GB flash card, by default one year at 1-minute intervals with up to 200 data points per minute (up to 5 years) and CSV export; IEC 61850, DNP 3.0, Modbus and TCP/IP over RS-232, RS-485, copper or fibre Ethernet and serial fibre. ### Full service solution - Monitors all key transformer components. - Consolidates data and manages communication to third party IEDs and DGAs on the transformer. - Provides a single point of communication for alarms. - LIFESTREAM® support services verify that units are implemented properly and provide training and support throughout the life cycle of the asset management programme. ### Monitoring capabilities Thermal | Top oil temperature, winding temperature, fibre optic, insulation ageing Bushings | Change in power factor, change in capacitance, partial discharge Power system | Harmonics, load profile, load power factor, voltage level Transformer faults | Fault detection, fault counting, fault magnitude accumulation Core, coil and DETC | DGA (key gas and multigas), moisture, partial discharge OLTC | Time since last thru neutral, tap counter, contact wear, excessive tap operations, motor failure, contact overheating, slow tap change, breather GIC | DC currents in the neutral and harmonics Cooling system | Fan and pump current, loss of cooling power, contactor fail, breaker trip, cooler efficiency, run hours Oil and preservation | Oil level with alarm, oil leak, conservator bladder rupture, breather, nitrogen pressure Control system | Panel heater, loss of auxiliary power, circuit breaker trip, cabinet door left open, not in auto ### Improved reliability With online condition-based data, users receive alarms when problems first arise, allowing action before they escalate. 50 % of bushing failures can end in a fire; offline testing is typically conducted every few years, whereas online monitoring is continuous and performed at normal operating temperature at the network voltage. The on-load tap changer has the highest failure rate of all devices on the transformer. The E3 gives early indication of OLTC drive or motor problems by monitoring motor current and voltage and alarming on any unexpected deviation. An individual counter is maintained for each tap position, providing a summary of historic operation. ### Reduced maintenance costs Advanced analytics filter through the condition data to automatically identify issues requiring maintenance attention, letting operations and maintenance crews resolve problems rather than manually collect data. Alarms are routed to the right stakeholders through multiple SCADA connections and email notifications, and can be grouped into common, major and minor alarm groups. E3 analytics include active moisture modelling, advanced thermal modelling — precise winding temperatures, insulation ageing, dynamic rating, "what if" rating calculations, predictive oil temperature model, cooling efficiency and cooling system health — and insulation health with fault counting. ### Maximised life and loading The dynamic rating provides the time remaining at the current state and the maximum safe load the transformer can carry given the present health of the cooling system and the environmental and operating conditions, without exceeding the thermal limit. Built on the predictive oil temperature model, the "what if" function answers two questions: how long the transformer can run at an assumed load before exceeding a limit, and what maximum load it can sustain over a given time. Predictive SMART cooling turns the cooling system on earlier to reduce insulation loss of life and reserve overload capacity for later in the day. Cooling control supports discrete control of more than four stages, dual speed fans, parallel pumps with automatic duty cycling for equal wear, and direct drive of variable speed drive systems. ### Safety - Online monitoring through SCADA connectivity, increasing situational awareness for crews entering substations. - Advanced analytics that ensure crews bring the right equipment and replacement parts: fewer trips to site means less exposure to hazards. - User interfaces providing key safety warnings, diagnostic interpretations and trouble shooting tips. ### Modules and architecture In addition to the CPU and power supply, both mandatory in any configuration, the E3 supports up to twelve modules. The multiport module counts as one of the twelve regardless of how many cards are installed on it. CPU and power supply | Connection via USB, copper ethernet or fibre ethernet.

Using the predictive oil temperature model, the "what if" calculations show how long a given load can be carried and the maximum load the transformer can sustain for a given time. **How much data does the E3 store?** A 1 GB industrial flash card stores data at user-defined intervals: by default one year at 1-minute intervals with up to 200 data points per minute, and up to five years, in CSV format, together with a time-stamped alarm history. The clock is synchronised by NTP, DNP or Modbus. **Which transformer components does the E3 monitor?** Bushings, windings, on-load tap changer, cooling system, oil and preservation system, core and coil, control system, through faults and geomagnetic induced currents. **Does it integrate with third party equipment?** Yes. Its open architecture allows integration with a wide array of third party multigas DGAs and moisture monitors over a serial link, which preserves measurement precision and gives access to additional diagnostic information. **Can it replace the existing voltage regulator?** The E3 provides voltage control for the transformer and can be configured as primary control or as backup for an existing system, reducing the number of devices and potential failure points. **How is the data accessed?** Every unit includes a software system with its own web pages: dynamic rating, transformer overview, harmonics, total harmonic distortion, voltage control and temperatures, available remotely at any time. **What does DynamicMetrix® add?** It aggregates data from multiple monitors into a single web-based visualisation solution, designed to prioritise decisions across a large fleet of transformers from each asset's current and historical status.

Continuous partial discharge monitoring for medium and high voltage rotating machines **Tracking the stator insulation condition of a medium or high voltage motor or generator without stopping it calls for a continuous partial discharge monitor that also correlates every reading with the temperature, load and humidity at that moment.** The RMM does this with 15 partial discharge channels per module acquired concurrently, a 70 dB dynamic range (3 mV to 10 V) with no gain adjustment and a 1 MHz to 20 MHz bandwidth, plus inputs for six winding temperatures, three load currents, three voltages and six 4-20 mA signals. It runs without a connected PC, stores up to two years of data and also works on machines fed from variable frequency drives. ### RMM key data - **Acquisition:** 15 partial discharge channels per module with concurrent data acquisition, with one or two optional 15-channel modules; the RMM accepts any brand of PD sensor, including those already installed on the machine. - **Measurement:** 70 dB dynamic range, 3 mV to 10 V, with no gain adjustment; 1 MHz to 20 MHz bandwidth; 7.5° power frequency phase resolution and 32 magnitude windows. - **Operating dynamics:** inputs for 6 RTD winding temperatures, 3 load currents, 3 voltages and 6 user-defined 4-20 mA signals; every base system includes an auxiliary CT and ambient humidity and temperature sensors. - **Detection zone:** coupling capacitors near the terminals and the RTD-PD module, which picks up through the RTDs the discharge produced deep inside the winding. - **Versions and analysis:** base systems for hydro generators, turbo generators or motors; motor current signature analysis to detect broken rotor bars in induction machines; suitable for VFD-fed machines. - **Data and communications:** up to 2 years in FIFO memory (8 MB internal) and standalone operation without a PC; Ethernet, USB and RS-485 with ModBus as standard and DNP-3 on request. - **Power and mounting:** 90-264 VAC (47-63 Hz) or 100-300 VDC; -40 to 70°C; standalone, panel, NEMA 4X enclosure or 316 stainless steel hazardous location enclosure (Class I Div. 1 B, C, D; Class II Div. 1 E, F, G; Class I Zone 1 IIB T4), the latter rated -20 to 40°C. ### Advantages **Trend instead of snapshot** Periodic measurement shows the condition of the insulation on the day of the test. Continuous monitoring shows how it evolves, which is what makes it possible to plan an intervention before the fault appears. The unit stores up to two years of data on a first-in, first-out basis. **Discharge and operating dynamics together** Inputs are available for six winding temperatures, three load currents, three voltages and six user-defined 4-20 mA signals, so the discharge activity can be correlated with what the machine was doing. **Standalone operation** The monitor runs on its own, with no computer attached, and still reports through its built-in interfaces, so it can be left permanently installed in a plant that has no dedicated maintenance network. ### Applications - Turbogenerators and hydrogenerators in power plants. - Large medium and high voltage motors driving critical processes. - Machines fed from variable frequency drives. - Detection of broken rotor bars in induction machines through current signature analysis. - Installations in hazardous areas, with the explosion-proof enclosure version. ### Detection across the whole winding Coupling capacitors pick up the discharge activity near the machine terminals. The RTD-PD module reaches the discharge produced deep inside the winding, where the temperature detectors already respond to its high-frequency content. Used together, both techniques widen the detection area, and four parameters are recommended for correlation with partial discharge on any machine: winding temperature, ambient temperature, relative humidity and load current. Existing sensors can be reused where the machine already has coupling capacitors fitted, which shortens the commissioning work and keeps the outage to a minimum. ### Results and software Results are presented in every format used in the industry: two-dimensional and three-dimensional phase-resolved patterns, the polar view over the phase circle, the pulse height distribution and the trend of each quantity over time, with several channels compared on the same screen. The dashboard software configures the instrument, downloads and stores the data and provides the analysis tools. ### Specifications and mounting - 15 partial discharge channels per module, acquired simultaneously. - 70 dB dynamic range, from 3 mV to 10 V, with no gain adjustment. - Measuring bandwidth from 1 MHz to 20 MHz and phase resolution of 7.5°. - Ethernet, USB and RS-485 interfaces, with ModBus as standard and DNP-3 on request. - Supply from 90 to 264 V AC at (47-63) Hz, or from 100 to 300 V DC. - Standalone, panel, enclosure or hazardous area mounting, the latter in 316 stainless steel. ### Frequently asked questions **Why monitor partial discharge continuously on a high voltage motor?** Studies by IEEE indicate that up to 40% of electrical-origin failures on HV motors are attributable to the stator insulation, mainly through partial discharge in windings and cables. A periodic measurement only shows the condition on the test day; the RMM records the trend continuously and stores up to two years of data, so the intervention can be planned before the failure. **How many sets of coupling capacitors does the machine need?** Turbo generators, small hydro generators and motors commonly use two sets: one at the line terminals and one in the isolated-phase bus duct, at least 2 m apart in a time-of-arrival configuration. Large hydro generators often need two to four sets, one per parallel phase group, with coaxial cable lengths adjusted. The RMM works with sensors that are already installed.

Solid-state dissolved hydrogen sensor for continuous monitoring of power and distribution transformers **Continuous monitoring of dissolved hydrogen, the first gas to reveal an arc, a partial discharge or a hot spot, calls for a hydrogen-specific sensor that mounts on a tank valve and needs no calibration gases and no periodic calibration.** GRIDSCAN5000 measures 25 to 5,000 ppm H2 in oil, or its in-oil equivalent from the head space, with ±20 % of reading or ±25 ppm accuracy (±10 % or ±15 ppm on the 5000-HP version), T90 response under 60 minutes and patented self-calibration, and delivers the reading over Modbus RTU or DNP3 on RS-485 from a 12 to 48 VDC supply. ### GRIDSCAN5000 key data - **Measuring principle:** hydrogen-specific solid-state palladium-alloy element, with cross-sensitivity below 2 % to H2O, CO2, C2H2, C2H4 and CO. GRIDSCAN5000 runs automatic reference cycles that remove drift, with no calibration gases, membranes or pumps. - **Range and accuracy:** 25-5,000 ppm H2 dissolved in oil, or 25-5,000 ppm in-oil equivalent on the gas-phase version; accuracy ±20 % of reading or ±25 ppm, whichever is greater (±10 % or ±15 ppm on the 5000-HP); repeatability ±10 % or ±15 ppm. - **Response and compensation:** T90 under 60 minutes once hydrogen reaches the sensor; GRIDSCAN5000 measures oil temperature with a built-in RTD to compensate the dissolved gas reading. - **Oil limits:** −40 to 105 °C within calibration (up to 135 °C without damage), −40 to 80 °C in gas phase and 0.1 to 10 bar pressure; supports mineral oil, silicone, natural ester and synthetic ester. - **Communication and power:** galvanically isolated two-wire RS-485, Modbus RTU and DNP3 (Modbus address 1, DNP3 source 4 and destination 3, 19,200 baud); 12-48 VDC and 10 W maximum; 4-20 mA output with the GRIDSCAN AO-1 module, scalable from 0-100 to 0-5,000 ppm. - **Mounting:** 3/4"-14 NPT thread on a ball or gate valve ≥ DN20, horizontal with air bleed in oil or horizontal or vertical in the head space; 151 × 39.6 × 39.6 mm and 387 g, with a single 4-wire M12 connector. - **Outdoor duty:** IP68 (7.62 m of water for 14 days), C5M marine corrosion class, ambient −40 to 70 °C and 30 g shock for 18 ms to IEC 60068-2-27. - **Certifications and logging:** FM 6520:2022 in liquid phase, CE marking, IEC 61010-1 and IEC 61326; GRIDSCAN5000 stores 1 year of history and carries a 3-year warranty on the unit and 10 years on the sensing element. ### Advantages **It warns before any other signal** Hydrogen is the first gas generated by an incipient arc, a partial discharge or a hot spot. Watching it rise in real time leaves room to schedule the intervention instead of discovering the problem in the six-monthly oil analysis. **No calibration, no consumables** The sensing element is solid state and calibrates itself: no membranes, no calibration gases, no pumps and no chromatography columns, and nothing to replace between transformer inspections. **Affordable fleet-wide** Its price and its simple installation make it viable to equip not only the critical assets but the whole fleet, which is where continuous monitoring really pays. **Built for outdoor service** IP68 ingress protection — 7.62 m of water for 14 days —, C5M corrosion class equivalent to a marine environment and operation from −40 to 70 °C, with vibration testing and a 30 g shock rating to IEC 60068. **Immediate integration** It communicates over Modbus RTU or DNP3 on two-wire RS-485, both stand-alone and inside third-party multi-gas monitors, and supports a 4-20 mA output through the matching module. ### Applications - Power and distribution transformers, new or in service. - Wind and solar farm transformers, with high harmonic content. - Network transformers installed in underground vaults. - Offshore platforms and substations in salt-laden air. - Railway traction and industrial transformers. ### About the product The oil-calibrated version mounts horizontally with the air-bleed assembly; the gas-calibrated version accepts horizontal or vertical mounting in the head space. Both need a 3/4" ball or gate valve (≥ DN20) and thread sealant, with no galvanised fittings. A single shielded four-conductor 18 AWG cable, with a female M12 connector and IP67/IP68 rating, carries power and communications to the control cabinet over typical runs of 5 to 30 m; from there, the RS-485 bus reaches up to 1,000 m. The sensor itself keeps one year of history, so a communications outage leaves no gap in the data. The Windows configuration utility connects over RS-485 or through an Ethernet-to-RS485 bridge and gathers the whole commissioning process into four tabs: real-time data with capture to CSV, protocol and address, clock synchronisation, owner, substation and transformer identification, and selection of the insulating liquid — mineral, silicone, natural ester or synthetic ester with its own Ostwald slope and offset. The range is completed by the high-performance version, accurate to ±10 % or ±15 ppm, the continuously self-calibrating version, which calibrates without interrupting the measurement, and an extended-range version from 250 to 50,000 ppm for nitrogen blankets with high concentrations. ### Technical specifications Measuring range | 25 to 5,000 ppm in oil; 25 to 5,000 ppm in-oil equivalent on the gas-phase version Accuracy | ±20 % of reading or ±25 ppm (±10 % or ±15 ppm on the high-performance version) Repeatability | ±10 % of reading or ±15 ppm, whichever is greater Response time | Under 60 minutes Cross-sensitivity | Below 2 % to H2O, CO2, C2H2, C2H4 and CO Data logging | 1 year of history held in the unit Insulating liquids | Mineral oil, silicone, natural ester and synthetic ester Temperatures | Ambient −40 to 70 °C; oil −40 to 105 °C; gas phase −40 to 80 °C Communications | Two-wire RS-485, Modbus RTU and DNP3; 19,200 baud, 8N1 as shipped Power supply | 12 to 48 VDC; 10 W maximum consumption Connection | 3/4"-14 NPT thread; 4-wire M12 electrical connector Dimensions | 151 × 39.6 × 39.6 mm Ingress protection | IP68 to IEC 60529; C5M marine corrosion class Certifications | CE marking, FM 6520:2022 in liquid phase, RoHS 2011/65/EU, IEC 61010-1 and IEC 61326 Warranty | 3 years on the unit and 10 years on the hydrogen sensing element Measuring principle | Hydrogen-specific solid-state palladium-alloy element; self-calibration through automatic reference cycles Oil limits | Pressure 0.1 to 10 bar; up to 135 °C without damage (calibrated up to 105 °C) Weight | 387 g ### Frequently asked questions **Which online hydrogen sensor is best for monitoring a whole transformer fleet?** One that is hydrogen-specific, needs no consumables or periodic calibration and installs on a tank valve. GRIDSCAN5000 screws onto a 3/4" valve, measures 25 to 5,000 ppm with ±20 % of reading or ±25 ppm, is powered at 12-48 VDC through a single four-wire M12 cable and communicates over Modbus RTU or DNP3, so it integrates into the SCADA of the whole fleet. **Is it installed in the oil or in the head space?** There are two factory-calibrated versions. The oil version mounts horizontally with the air-bleed assembly, on a ball or gate valve of at least DN20 and away from turbulent oil flow; the gas-phase version mounts horizontally or vertically in the head space and reports hydrogen as an in-oil equivalent, because the head-space concentration is about 20 times higher than the dissolved one. Both GRIDSCAN5000 versions measure 25 to 5,000 ppm. **Does it need periodic calibration?** No. The sensor self-calibrates and corrects drift, so the reading stays valid without calibration or removal throughout its service life. **Does it work with ester or silicone transformers?** Yes. It supports mineral oil, silicone, natural ester and synthetic ester; the liquid type is selected in the configuration software. **How long before the first reliable reading?** The unit runs its self-test and a start-up sequence once powered which, on a new installation or after a long outage, can last up to 16 hours before it delivers stable, accurate readings; after a short outage it gives approximate readings within about 30 minutes. **How does it integrate with SCADA?** Through Modbus RTU or DNP3 on two-wire RS-485. Factory settings are Modbus address 1, DNP3 source 4 and destination 3, 19,200 baud and 8N1. A 4-20 mA signal is also available through the matching module. **Can it be fitted with the transformer in service?** It mounts on a 3/4" valve, following the bleed procedure that matches the sensor type. Installation must be carried out by qualified personnel authorised to work on the transformer. --- ## Hydrogen Area Monitor URL: https://amperis.com/en/products/battery-maintenance-and-charging/hydrogen-area-monitor/ Category: [Battery maintenance, charging & testing](https://amperis.com/en/products/battery-maintenance-and-charging/) Series: Battery maintenance and charging datasheet: https://amperis.com/MONITOR-H2_ENG.pdf > HY-GUARD hydrogen monitor for battery rooms: hydrogen-specific solid-state sensor, 0.4-5 %, ±0.3 %, 1 % and 2 % relays, Modbus and 4-20 mA. Maintenance-free hydrogen area monitor for battery rooms, with a hydrogen-specific solid-state sensor **A battery room needs a hydrogen-specific detector that alarms well below the lower flammability limit, drives the ventilation through a relay and needs no periodic calibration.** The HY-GUARD monitor measures H2 from 0.4 to 5 % by volume with ±0.3 %, switches its relays at 1 % — 25 % of the lower flammability limit — and at 2 %, signals faults through a third relay and communicates over Modbus RTU and 4-20 mA, with continuous self-calibration and a maintenance-free service life of more than 10 years. ### HY-GUARD key data - **Measuring principle:** hydrogen-specific solid-state sensor with no cross-sensitivity to other gases, so the HY-GUARD avoids the false alarms and drift of catalytic-bead and metal-oxide sensors; two non-consumable sensors alternate, and while one measures the other corrects its drift every 12 hours. - **Range and accuracy:** 0.4-5 % H2 by volume, with a 0.4 % lower detection limit and ±0.3 % H2 absolute accuracy (±1 % above 2 %); prolonged exposure above 5 % may damage the sensor. - **Alarms and relays:** three changeover relays rated 12 A at 125 VAC or 28 VDC for the 1 % H2 low alarm, the 2 % high alarm and fault; the fault relay stays energised in normal operation and de-energises on a fault. Local indication through LEDs and an 85 dB buzzer. - **Communications:** Modbus RTU over two-wire RS-485 (19,200 baud default, address 1-247) and a 4-20 mA output linear from 0 to 5 % H2, with 2 mA during warm-up and 3 mA on error; model 8111 combines all outputs and models 8110, 8101 and 8100 are variants with fewer outputs. - **Power and start-up:** AC or 15-60 VDC with automatic switchover and 10 W maximum; once powered, the HY-GUARD warms up for up to 6 minutes before entering normal monitoring. - **Installation:** at the highest point of the room, cabinet or enclosure, because hydrogen rises; direct punch-out mounting, on a 4-11/16" junction box or, with the adapter plate, on 35 mm DIN rail, a flat surface or a magnetic mount; 132.5 × 130.5 × 52.9 mm and 0.5 kg. - **Environment:** rated 15 to 40 °C and operational −25 to 50 °C, 0-95 % RH non-condensing, 0.8-1.2 atm and up to 2,000 m altitude, indoors. - **Standards and certifications:** IEC 61010-1, CE, FCC Part 15, REACH and RoHS; the HY-GUARD helps meet IFC, NFPA 1, NFPA 2, NFPA 855, OSHA 1910, IEC 62485-2, IEC 62933-5-2 and IEEE 484 & 1635. ### Advantages **Hydrogen safety without maintenance** A hydrogen-specific sensor with continuous internal self-testing verifies its own health and accuracy over its whole life, with no manual calibration and no board replacements. **No false alarms** The sensor has no cross sensitivity to other gases, eliminating the drift, false triggers and premature failures typical of catalytic-bead and metal-oxide sensors. **Compliance built in** It keeps installations aligned with global fire and safety standards — IFC, NFPA 1, NFPA 2, NFPA 855, OSHA 1910, IEC 62485-2, IEC 62933-5-2 and IEEE 484 & 1635. **Measured and reliable** It measures H2 from 0.4 to 5 % with ±0.3 % accuracy and a 50-70 second response, providing 1 % and 2 % concentration alarms and a fault indicator. **Flexible integration** Modbus RTU (RS-485), 4-20 mA analog output and dry relay contacts, with wall, DIN-rail, junction-box and magnetic mounting and AC/DC power with automatic switchover. ### Applications - Standby-power and emergency battery rooms. - Lead-acid and NiCad battery installations and cabinets. - Telecommunications backup and data-centre standby power. - Electrical substations, switchgear and SCADA systems. - Hydrogen generation, forklift charging and fuel-cell applications. ### About the product The monitor runs on 85-264 V AC and 15-60 V DC with automatic switchover and a service life above 10 years; four models cover the communication needs of each installation — 8111 (Modbus RTU, 4-20 mA, dry contacts and fault indicator), 8110 (4-20 mA and dry contacts), 8101 (Modbus RTU and dry contacts) and 8100 (dry contacts with 1 % and 2 % alarms). ### Technical specifications Detection range | 0.4-5 % H2; lower detection limit 0.4 % Accuracy | ±0.3 % H2 (±1 % above 2 %) Response time | 50 to 70 seconds Alarms | 1 % and 2 % H2 concentration; fault indicator Communication | Modbus RTU (RS-485); 4-20 mA analog; dry relay contacts Power | 85-264 V AC; 15-60 V DC; automatic AC/DC switchover; 10 W max Mounting | Wall, DIN-rail, junction box and magnetic Service life | Above 10 years; maintenance-free, no calibration Environment | 15 to 40 °C; 0-95 % RH non-condensing Dimensions and weight | 132.5 × 130.5 × 52.9 mm; 0.5 kg Models | 8111, 8110, 8101 and 8100 (communication variants) Relays | 3 changeover (1 %, 2 % and fault); 12 A at 125 VAC / 28 VDC; fault relay energised in normal operation Analog output | 4-20 mA = 0-5 % H2; 2 mA during warm-up, 3 mA on error Certifications | IEC 61010-1, CE, FCC Part 15, REACH and RoHS ### Frequently asked questions **Which hydrogen detector is best for a battery room?** One that is hydrogen-specific, does not react to other gases, watches the 1 % H2-in-air threshold — 25 % of the lower flammability limit set by the codes — and starts the exhaust through a relay. The HY-GUARD measures 0.4 to 5 % with ±0.3 %, switches relays at 1 % and 2 %, has a fault relay that de-energises on any abnormality and needs no calibration for more than 10 years. **Where should it be placed in the battery room?** At the highest point of the room, cabinet or enclosure, because hydrogen is much lighter than air and collects at the top; the HY-GUARD is for indoor use. It mounts directly through the punch-out, on a 4-11/16" junction box or, with the adapter plate, on 35 mm DIN rail, a flat surface or a magnetic mount, and several units can share the RS-485 bus, with the terminating resistor enabled on the last one. **What does it detect?** Hydrogen (H2) from 0.4 to 5 % by volume, with a lower detection limit of 0.4 % and ±0.3 % accuracy. **Does it need calibration?** No. It is maintenance-free, with continuous automated self-calibration and no board replacements over a 10-year-plus service life. **Which standards does it help meet?** IFC, NFPA 1, NFPA 2, NFPA 855, OSHA 1910, IEC 62485-2, IEC 62933-5-2 and IEEE 484 & 1635, among others. **How does it communicate?** Through Modbus RTU (RS-485), a 4-20 mA analog output and dry potential-free relay contacts, with 1 % and 2 % alarms. **How is it mounted and powered?** Wall, DIN-rail, junction-box or magnetic mounting, with 85-264 V AC and 15-60 V DC power and automatic switchover. --- ## Insulating Oil Dielectric Loss & Resistivity Tester URL: https://amperis.com/en/products/transformers-testing/hzjd-2z/ Category: [Transformers Testing](https://amperis.com/en/products/transformers-testing/) Series: Transformers Testing datasheet: https://amperis.com/en/products/transformers-testing/hzjd-2z/Catalogo-HZJD-2Z-EN.pdf > HZJD-2Z: measures tanδ from 0.00001 to 100 (±1 % + 0.0001), relative permittivity and DC resistivity up to 20 TΩ·m of insulating oils to IEC 60247. Test cell, temperature control, AC/DC sources and standard capacitor in a single automatic instrument **Measuring the dielectric dissipation factor (tanδ), relative permittivity and DC resistivity of an insulating oil to IEC 60247 takes a three-electrode cell heated to a controlled temperature, an AC source, a DC source and a stable standard capacitor.** The HZJD-2Z combines all of them in one automatic instrument: it measures tanδ from 0.00001 to 100 with an accuracy of ±(1 % of reading + 0.0001), relative permittivity from 1.000 to 30.000 and DC resistivity from 2.5 MΩ·m to 20 TΩ·m, with test voltages of 500-2000 V AC and 0-500 V DC, on a sample of about 40 mL heated up to 125 °C. ### HZJD-2Z key data - **Dielectric dissipation factor:** the HZJD-2Z measures tanδ from 0.00001 to 100 with an accuracy of ±(1 % of reading + 0.0001) and a resolution of 0.00001. - **Permittivity and capacitance:** relative permittivity from 1.000 to 30.000 with ±1 % of reading and 0.001 resolution; cell capacitance from 5 to 200 pF with ±(1 % of reading + 0.5 pF) and 0.01 pF resolution. - **DC resistivity:** from 2.5 MΩ·m to 20 TΩ·m with an accuracy of ±10 % of reading. - **Test voltages:** 500-2000 V RMS AC at 50 Hz and 0-500 V DC, both continuously adjustable, generated by AC-DC-AC conversion so that mains fluctuations do not affect the result, even when the instrument runs from a generator. - **Cell and temperature:** three-electrode stainless-steel cell with a 2 mm gap, 60 ± 5 pF empty capacitance, empty-cell tanδ below 1 × 10−4 and about 40 mL of sample; medium-frequency induction heating with PID control from 0 to 125 °C (±0.5 °C error) and a limiting relay at 120 °C. - **Reference:** three-electrode SF6 gas-filled standard capacitor whose loss and capacitance do not depend on ambient temperature or humidity. - **Operation and recording:** 800 × 480 colour touch screen with guided menu, automatic dry-cell calibration, built-in printer, RS-232 port and DataScan function with up to 100 date- and time-stamped records; over-voltage, over-current and high-voltage short-circuit protection. - **Standards and physical data:** CE, IEC 60247, ASTM D924, ASTM D1169, GB/T 5654-2007, GB/T 507-2002, DL 429.9-91 and DL/T 846.7-2004; 220 V AC ±10 %, 50/60 Hz, 100 W; 500 × 360 × 420 mm and 22 kg; operation from 0 to 40 °C at relative humidity below 75 %. ### All-in-one architecture The instrument integrates the three-electrode test cell, the temperature controller and sensor, the dielectric-loss bridge, the AC test source, the SF6 standard capacitor, the high-resistance meter and the DC high-voltage source into a single unit. The three-electrode cell, with a 2 mm gap between the high-voltage electrode and the measuring electrode, eliminates the effect of stray capacitance and leakage on the tanδ result. The sample is heated by medium-frequency, non-contact induction with PID control that keeps the temperature within the preset error band between 0 and 125 °C, and a thermal limiting relay stops heating above 120 °C. ### Applications The instrument suits the diagnostic testing of insulating liquids wherever tanδ, permittivity and resistivity are required for acceptance or periodic checks. - Power transformers and other critical assets. - Substations and transmission and generation facilities. - Oil laboratories and acceptance or maintenance testing. ### Touch interface and result management Measurement is full digital and fully automatic, run from an 800×480 full-touch colour screen with a guided menu, so any operator, without specialised training, completes a full automatic test from start to finish. The automatic test report shows the oil-cup capacitance Cx, tanδ, the relative permittivity εr and the DC resistivity ρ, with on-board printing. The DataScan function stores up to 100 records, each with the test temperature, the test voltage, the three results and the date and time, and it can recall and print them at any later moment. A built-in oil-drain control, with an on-screen confirmation prompt, empties and rinses the cell without removing it between tests. ### Technical specifications AC test voltage | 500-2000 V, continuously adjustable, 50 Hz DC test voltage | 0-500 V, continuously adjustable Measured temperature range | 0-125 °C, ±0.5 °C error HV-LV electrode gap | 2 mm Dimensions (W×D×H) | 500 × 360 × 420 mm Weight | 22 kg Power supply | AC 220 V ±10%, 50/60 Hz, 100 W Standards | IEC 60247, ASTM D924, ASTM D1169, GB/T 5654-2007 Dielectric dissipation factor (tanδ) | 0.00001-100; accuracy ±(1 % of reading + 0.0001); resolution 0.00001 Relative permittivity / capacitance | 1.000-30.000, ±1 % of reading, resolution 0.001 / 5-200 pF, ±(1 % of reading + 0.5 pF), resolution 0.01 pF DC resistivity | 2.5 MΩ·m-20 TΩ·m; accuracy ±10 % of reading ### Frequently asked questions **How accurate is the HZJD-2Z for tanδ and resistivity?** The HZJD-2Z measures tanδ from 0.00001 to 100 with ±(1 % of reading + 0.0001) and 0.00001 resolution, relative permittivity from 1.000 to 30.000 with ±1 % and DC resistivity from 2.5 MΩ·m to 20 TΩ·m with ±10 % of reading. The empty cell has an intrinsic tanδ below 1 × 10−4. **Can it run from a generator in the field?** Yes.

Fully automatic 1 A digital micro-ohmmeter for resistances from 1 µΩ to 200 Ω, in the field and on the bench **Inspecting earth connections, busbars, welded joints and circuit-breaker and fuse contacts in the field calls for a lightweight four-point micro-ohmmeter with micro-ohm resolution and a mode that compares each point against a reference.** The PDRM-1A measures from 1 µΩ to 200 Ω with 1 µΩ resolution over 4¾ digits and an accuracy of 0.1% of reading ±2 counts, adjusts the 1 A, 100 mA or 5 mA DC test current to the range by itself and, in differential mode, shows the deviation of each reading from a stored reference measurement; it weighs 0.86 kg and performs over 4000 measurements at 1 A on six AA NiMH batteries. ### PDRM-1A key data - **Range and resolution:** 1 µΩ to 200 Ω with automatic range selection; 1 µΩ resolution over 4¾ digits. - **Accuracy:** the PDRM-1A measures with 0.1% of reading ±2 counts. - **Test currents:** 1 A, 100 mA and 5 mA DC, automatically adjusted; the low current protects applications with small measuring contacts. - **Measurement method:** four-point Kelvin; the microprocessor cancels offset and parasitic voltages, and the filtered inputs keep the reading stable in strong magnetic fields. - **Differential mode:** the PDRM-1A stores the reading from a reference connection and shows the deviation of every new reading, to decide quickly whether each point of an earthing grid is acceptable. - **Autonomy:** six rechargeable AA NiMH batteries, with over 4000 measurements at 1 A and over 10,000 at the other currents; automatic shutdown after 2 minutes and backlight off after 30 seconds. - **In the field:** sealed, shock-resistant 203 × 114 × 51 mm enclosure weighing 0.86 kg; operation from -20 to +50°C, storage from -40 to +50°C and 0 to 95% humidity, non-condensing; 128 × 64 pixel LCD with two-level backlight. - **Accessories:** dual hand probes with spring-loaded tips (122 cm; heavy-duty version up to 3 m), 35 mm and 19 mm Kelvin clamps, exothermic weld probe, cable-elbow accessory and 9.5 µΩ reference resistance. ### Advantages **Category-leading accuracy** The instrument resolves 1 µΩ over 4¾ digits with an accuracy of 0.1% of reading ± 2 counts, using three test currents — 1 A, 100 mA and 5 mA — that adjust automatically to the range. **Four points, no contact resistance** Two leads inject the current at the ends of the joint while another two read the voltage drop directly across the section under test, so contact resistance stays out of the measurement; the microprocessor also cancels offset and parasitic voltages. **Stable readings near live busbars** Heavily filtered inputs keep the reading accurate even in the presence of strong magnetic fields, a condition frequently found in substations and switchgear rooms. **Built for field and bench work** At 0.86 kg and 203 × 114 × 51 mm, the sealed, shock-resistant enclosure operates from -20°C to +50°C, and the backlit LCD display can be read in dark locations. **Rechargeable autonomy** Six rechargeable NiMH AA batteries deliver over 4000 measurements at 1 A and more than 10,000 at the lower currents, with automatic shutdown after 2 minutes of inactivity. ### Applications - Checking earth connections and power busbars using the relative measurement mode against a stored reference. - Verification of welded joints made with high current and of mechanical connections. - Testing circuit-breaker contacts and power fuses. - Quality control of castings and electrodes, and non-destructive verification of exothermic welds. ### About the product The differential mode stores the reading from a reference connection — for example, an earth connection known to be in good condition — and compares every new measurement against it, displaying the deviation; this speeds up inspection campaigns across large earthing grids. Low current injection protects applications with small measuring contacts, and the display backlight switches off after 30 seconds to save battery power. The kit includes the micro-ohmmeter, the Kelvin clamps, the batteries, the manual and the calibration certificate. Available accessories: dual hand probes with replaceable spring-loaded tips, 35 mm and 19 mm Kelvin clamps, a dedicated probe for exothermic welds, a cable-elbow accessory, a 9.5 µΩ reference resistance, and a nylon pouch or rigid transport case. ### Technical specifications Measurement range | 1 µΩ to 200 Ω, automatic range selection Test currents | 1 A, 100 mA and 5 mA DC, automatically adjusted Resolution | 1 µΩ; 4¾ digits Accuracy | 0.1% of reading ± 2 counts Measurement method | Four-point Kelvin Operating modes | Standard and differential Power supply | Six rechargeable NiMH AA batteries Dimensions and weight | 203 × 114 × 51 mm; 0.86 kg Display | 128 × 64 pixel LCD, 60 × 41 mm; two-level backlight (100% and 50%) Autonomy | Over 4000 measurements at 1 A; over 10,000 at the other currents Environmental conditions | Operation from -20 to +50°C; storage from -40 to +50°C; 0 to 95% humidity, non-condensing ### Frequently asked questions **When is the PDRM-1A enough, and when is the PDRM-10A the better choice?** It depends on the resolution and current the measurement needs. The PDRM-1A resolves 1 µΩ with up to 1 A DC and an accuracy of 0.1% of reading ±2 counts; if readings below 1 µΩ or more current are needed, the PDRM-10A resolves 0.01 µΩ and injects up to 10 A DC, in the same size and the same 0.86 kg. **What does the PDRM-1A kit include, and which accessories are worth adding?** The kit includes the micro-ohmmeter, the Kelvin clamps, the AA batteries, the manual and the calibration certificate. Dual hand probes with spring-loaded tips speed up measurement on any surface, and the 9.5 µΩ reference resistance lets you validate the instrument before starting a job. **Why does the instrument measure at four points?** Because the current and the voltage use separate pairs of leads, so the resistance of the leads and the contacts stays outside the reading circuit and does not distort the result. **Can it be used near energised equipment?** Yes. The filtered inputs keep the reading stable even with strong magnetic fields present, which makes the instrument usable in live substations. **What is the differential mode used for?** It stores a reference measurement and compares every new reading against it, showing the deviation; this is the recommended method for inspecting a series of earth connections. **How much autonomy do the batteries provide?** The six rechargeable NiMH AA batteries exceed 4000 measurements at 1 A and 10,000 measurements at the 100 mA and 5 mA currents. **Is it suitable for exothermic welds?** Yes. With the optional dedicated probe, the instrument verifies exothermic connections non-destructively, a common requirement in substation earthing grids. --- ## PADD Lightning Rod Flaw Detector URL: https://amperis.com/en/products/partial-discharge-detector/add/ Category: [Partial Discharge Detection](https://amperis.com/en/products/partial-discharge-detector/) Series: Partial Discharge Detector datasheet: https://amperis.com/en/products/partial-discharge-detector/add/Brochure-PADD.pdf > PADD: contact detector of defective arresters on energised overhead lines up to 69 kV, with 6 levels in 2 zones, audible alert and Auto-Test. Portable partial discharge detector for arresters and overhead medium-voltage accessories, with two-zone visual and audible indication. **Locating the defective metal-oxide arrester that causes radio or TV interference requires checking each arrester by contact, with the line energised, using a partial discharge detector, because directional radio-frequency locators cannot single out the specific arrester.** The PADD carries out that check on overhead lines up to 69 kV (45 kV phase-to-neutral): its hook electrode rests on the bare conductor next to the arrester, detects the discharge by ultra-wide-band radio frequency and indicates it on 6 levels arranged in 2 colour zones, with an audible alert at the highest levels. ### PADD key data - **Application:** metal-oxide arresters, dry-type transformers, bushings and insulators on medium-voltage networks, on energised overhead lines up to 69 kV (45 kV phase-to-neutral). - **Detection principle:** direct-contact method with ultra-wide-band radio-frequency detection; the electrode is applied to the bare conductor as close as possible to the arrester being checked. - **Indication:** 6 levels in 2 colour zones, 3 low in blue and 3 high in red, with an audible signal at the highest levels; the red zone indicates partial discharge or sparking inside or on the surface of the arrester. - **Location:** by checking each arrester individually in a three-phase overhead installation, it identifies the one causing the interference and avoids replacing arresters that are not defective. - **Verification:** Auto-Test function before each use, independent battery-status indicator and a power light that changes from slow blinking to steady when the line voltage is detected. - **Equipment:** very lightweight handheld unit for a single operator, with a built-in universal adapter for an insulated handling bar, a 60mm hook electrode as standard (Y-type as an alternative), 1 9V alkaline battery and carrying case. ### Advantages **Accurate location of the defective arrester** Unlike directional radio-frequency detection equipment, the PADD makes it possible to identify exactly which arrester is causing radio or TV interference, so only the defective part needs to be replaced instead of the whole group of nearby accessories. **Two-zone, six-level indication** The PADD's light indicators are arranged in two colour zones: the blue zone shows three low levels of partial discharge and the red zone three high levels, with an additional audible signal when the detected activity is very high. **Prior verification with the Auto-Test function** The unit includes a self-test (Auto-Test) function that confirms the detector is working correctly before each inspection, together with its own battery-status indicator. **Lightweight design ready for an insulated hotstick** The PADD is a very lightweight unit, adapted for use under voltage and compatible with an adapter for an insulated handling bar, and is carried in an included case together with its contact electrodes. ### Applications - Partial discharge detection on metal-oxide arresters installed on overhead lines up to 69 kV. - Inspection of in-service dry-type transformers, bushings and insulators on medium-voltage networks. - Locating the specific arrester causing radio or TV interference in the area. - Preventive arrester maintenance programmes on overhead distribution networks. ### About the product The unit consists of a handheld device with a hook-shaped contact electrode, applied to the bare live conductor as close as possible to the arrester being checked. A panel of light indicators, arranged in two colour zones, shows the detected partial discharge level, and an audible signal activates when the recorded activity is very high. The unit includes a built-in universal adapter for attaching an insulated handling bar, allowing the check to be carried out without direct contact between the operator and the energised part, together with an Auto-Test function that verifies the unit is working correctly before each use. The unit is powered by a 9V alkaline battery and is carried in an included case together with its contact electrodes. Available accessories: 60mm hook-type contact electrode, Y-type contact electrode, adapter for insulated handling bar and carrying case. ### Technical specifications Maximum line voltage | Up to 69 kV (45 kV phase-to-neutral) Indication levels | 6 levels in 2 colour zones: 3 low (blue) and 3 high (red) Indication type | Visual and audible Self-test | Built-in Auto-Test function Hotstick adapter | Built-in universal adapter for insulated handling bar Power supply | 1 9V alkaline battery, included Battery indicator | Battery-status indicator Weight and case | Very lightweight unit; carrying case included Detection technology | Direct contact with ultra-wide-band radio-frequency detection, for energised lines Contact electrode | 60mm hook as standard; Y-type electrode as an alternative Operation | By a single person ### Frequently asked questions **How do I know the PADD is resting on an energised line?** When the PADD is switched on, the power light blinks slowly; when the hook electrode touches the conductor and the unit detects the line voltage, the light becomes steady. Before each inspection, the Auto-Test function confirms that the detector is working correctly. **Why does the PADD locate the defective arrester better than a radio-frequency interference locator?** A directional radio-frequency locator only points to the pole the interference comes from, not to the specific arrester. The PADD is applied by contact next to each arrester of the three-phase installation, so it identifies the defective one and only that arrester needs replacing. **Is contact with the conductor needed to measure?** Yes. The PADD works by direct contact: the hook electrode is applied to the bare live conductor, as close as possible to the arrester being checked. **How many indication levels does it have?** Six, arranged in two colour zones: the blue zone indicates three low levels of partial discharge and the red zone three high levels. **Can it be used with the line energised?** Yes, the unit is designed for use on energised medium-voltage overhead lines, up to 69 kV, with an adapter for an insulated handling bar. **What accessories does it include or accept?** The 60mm hook-type contact electrode, the Y-type electrode as an alternative, the hotstick adapter and the carrying case. --- ## Powerline analyser SHARK 100-S URL: https://amperis.com/en/products/electric-panel-multimeters/serie-shark/shark-100-s/ Category: [Shark Series: energy and power meters](https://amperis.com/en/products/electric-panel-multimeters/serie-shark/) Series: Serie SHARK datasheet: https://amperis.com/en/products/electric-panel-multimeters/serie-shark/shark-100-s/Brochure-Shark-100-S.pdf > Shark 100-S: 0.2 % class ANSI C12.20 energy submeter with IEEE 802.11b WiFi, RJ45 Ethernet and Modbus TCP, RS485, KYZ pulse and THD with the V4 key. 0.2 % class energy submeter with RJ45 Ethernet and IEEE 802.11 WiFi **Submetering the energy of each area, tenant or unit in a building and sending the data to central software without running serial buses takes a revenue-class submeter that communicates over the existing Ethernet or WiFi network.** The Shark 100-S measures energy and demand to 0.2 % class under ANSI C12.20 and IEC 687, sampling over 400 times per cycle on all channels simultaneously, and sends the data over IEEE 802.11b WiFi or 10BaseT RJ45 Ethernet with Modbus TCP, or over RS485 with Modbus RTU/ASCII, from a wall-mount enclosure that works with standard 1 or 5 A split-core or doughnut CTs.

The unit is specially designed for sub-metering applications, high accuracy with advanced communications and ease of installation. V-Switch technology, measurement upgrade packages The Shark 100-S is equipped with EIG's exclusive V-Switch® technology. V-Switch® is a virtual (firmware-based) switch that allows you to add additional measurement features to your meter via communication, even when the meter is already installed. Using V-Switches, you can purchase what you need today and upgrade the functions in the field according to your needs. This allows you to optimize your investment in measurement. Start with a simple energy sub-meter and upgrade to an advanced energy meter with power quality and alarm functions. V-Switches available: - V-Switch 3 - Volts, Amperes, kW, kVAR, FP, kVA, Freq. kWh, kVAh, kVARh - V-Switch 4 - Volts, Amps, kW, kVAR, FP, kVA, Freq. kWh, kVAh, kVARh, %THD Monitoring and Limit Exceeded Alarms Advanced communication capability with IrDA interface The meter provides a wide range of outputs, as it can be equipped with any of the following media: RS485 Communication Standard Standard communications include an RS485 output with Modbus protocol. This makes it possible for the meter to be connected to any RS485 serial bus using a Modbus interface. The unit will communicate easily with most building automation systems or software applications. Ethernet RJ45 or Wi-Fi© Wireless The equipment has a WiFi or RJ45 connection option, which allows the SHARK100 to be used in standard WiFi based stations. The meter will assign an IP address and use TCP/IP protocol over Ethernet. IrDA Port for PDA Read Using the infrared port, the Shark 100-S can display or capture information via a laptop or PDA device. KYZ pulse In applications where a pulse is necessary, the meter also provides a KYZ output, which pulses in proportion to the amount of energy consumed. This is used in pulse counting applications for building management systems when serial or ethernet communication is not available. Watt-Hour Test Pulse, Traceable for Accuracy Certification In order to be certified for billing measurement, Electric Utilities need to know if the meter will perform with the accuracy indicated by the Manufacturer. To verify the meter's performance and calibration, Electric Utilities use field verification equipment (Standards), to ensure that energy measurements are correct. Since the Shark 100-S is a traceable billing meter, it contains a Test Pulse, which is used to verify that the equipment is performing at the manufacturer's specified accuracy. This is an essential feature required on every billing grade meter. Cost Determination/Location Using the Energy Manager HMI Software, you can record and graph energy and demand, to provide energy use and demand billing. You can also add various rate structures per meter and increase the desired number of metering and billing points. **Determination / location of costs: SHARK 100S Powerline Analyzer** [Software energy manager - HMI] | [Data exported to spreadsheet] Peak Demand Measurement for Electric Companies The Shark 100-S provides user-configurable Block Window or Dynamic Window demand. This allows you to configure a particular demand profile. The Block Window is used over a fixed period of demand configured per user (usually 5, 15 or 30 minutes). The Dynamic Window is a fixed window of Demand that moves to a period of Sub-Interval configured by user. An example would be a 15 Minute Demand using 3 sub intervals, providing a new Demand reading every 5 minutes based on the last 15 minutes. Readings for kW, kVAR, kVA and PF are calculated using utility structures. All other parameters provide max and min capability over a user-selectable averaging period. The Voltage provides an instantaneous max and min reading, displaying the highest Surge and lowest Sag sensed by the Meter. Ethernet WiFi connection: Very simple and practical wireless architecture The meter is designed with the latest technology, providing a wireless communication architecture that is easy to integrate and reliable in its performance.

Up to 600 A of true ripple-free DC current in a 7-8 kg device **Measuring the contact resistance of a medium- or high-voltage circuit breaker takes a four-wire (Kelvin) micro-ohmmeter with a high DC current, as IEEE C37.09 and IEC 62271-100 call for, kept stable and resolved to tenths of a micro-ohm.** RMO-A does it with six models from 100 to 600 A DC and ripple below 1 %: the current rises and falls in automatically regulated ramps that remove magnetic transients, and the measurement has 0.1 µΩ resolution and ±(0.1 % of reading + 0.1 % of full scale) typical accuracy, in a 7 to 8 kg instrument. ### RMO-A key data - **Models and current:** RMO100A to RMO600A, 100 to 600 A DC with ripple below 1 %; continuous operation at 100 A and 20 to 150 s at maximum current depending on the model. - **Range and resolution:** 0.1 µΩ to 999.9 mΩ, expandable to 6 Ω; 0.1 µΩ resolution and, with the optional high-precision module, 0.01 µΩ between 1 and 30 µΩ. - **Accuracy:** ±(0.1 % rdg + 0.1 % FS) typical and ±(0.2 % rdg + 0.2 % FS) guaranteed, with filtering that cancels interference from high-voltage electric fields. - **Test modes:** SINGLE (spot measurement), CONTIN (sustained current for longer tests) and DTRtest (saturates the current transformers of dead-tank breakers before measuring); pass/fail assessment with an Rmax limit. - **Long or thin cables:** the high output voltage allows testing at 100 A with 20 m of cable of only 16 mm². - **In the field:** 198 × 255 × 380 mm, 7 to 8 kg, −20 to +55 °C and IP50; memory for 500 time- and date-stamped measurements, USB (RS232 and Bluetooth optional) and optional thermal printer. ### Advantages **Laboratory accuracy in the field** Typical accuracy of ±(0.1% of reading + 0.1% of full scale) and 0.1 µΩ resolution, with filtering that cancels the interference of high-voltage electric fields. **Three modes for every situation** SINGLE mode solves the spot measurement, CONTIN generates sustained current for longer tests and DTRtest saturates the current transformers of dead-tank breakers before measuring. **Power that gives margin** The high output voltage widens the measuring range at high currents and accepts long or thin cables: 20 m of only 16 mm² to test at 100 A. **Results in order** The internal memory stores 500 time- and date-stamped measurements, and an optional thermal printer prints the result right at the breaker. ### Applications - Contact resistance of medium- and high-voltage breakers, live tank and dead tank. - Disconnectors, busbars and high-current joints. - Cable splices, welded joints and fuses. - Switchgear manufacturing, commissioning and maintenance. - Pass/fail verification with Rmax limit. ### About the product The measuring range spans 0.1 µΩ to 999.9 mΩ, expandable to 6 Ω, and an optional high-precision module resolves 1 to 30 µΩ with 0.01 µΩ. The PC software controls the test from the PC over USB or RS232, records at configurable intervals and generates reports with export to Excel. Accessories: current cables of several cross-sections and lengths, sense cables with clamps, verification shunt, transport bag, optional thermal printer and Bluetooth. ### Technical specifications Models | RMO100A to RMO600A (100 – 600 A DC) Measuring range | 0.1 µΩ – 999.9 mΩ; expandable to 6 Ω Typical accuracy | ±(0.1% rdg + 0.1% FS) Current ripple | Below 1% Memory | 500 time- and date-stamped measurements Communication | USB; optional RS232 and Bluetooth Operating temperature | -20 to +55 °C; IP50 Dimensions and weight | 198 × 255 × 380 mm; 7 to 8 kg Guaranteed accuracy | ±(0.2 % rdg + 0.2 % FS) ### Frequently asked questions **Which micro-ohmmeter do I need to measure the contact resistance of a high-voltage circuit breaker?** A four-wire instrument with a high DC current, because IEEE C37.09 and IEC 62271-100 call for high currents on breaker contacts. RMO-A offers 100 to 600 A DC depending on the model (RMO100A to RMO600A), 0.1 µΩ resolution and ±(0.1 % of reading + 0.1 % of full scale) typical accuracy, with a DTRtest mode for dead-tank breakers. **How accurate is the RMO-A when measuring micro-ohms?** Typical accuracy is ±(0.1 % of reading + 0.1 % of full scale) and guaranteed accuracy ±(0.2 % of reading + 0.2 % of full scale), with 0.1 µΩ resolution over the 0.1 µΩ to 999.9 mΩ range. For very low resistances, the optional high-precision module resolves 1 to 30 µΩ with 0.01 µΩ. **Which model do I need?** It depends on the required test current: IEEE C37.09 and IEC 62271-100 call for high currents on breaker contacts, and the series goes from 100 to 600 A. **Why does the current ramp up?** Because abrupt current changes induce magnetic transients in the test object; the automatic ramp removes them and stabilises the reading. **Can it measure dead-tank breakers?** Yes. The DTRtest mode first saturates the breaker's current transformers and then measures, avoiding the magnetisation error. **How long can it hold the current?** At 100 A, continuously; at maximum current, 20 to 150 seconds depending on the model, with duty cycles that prevent overheating. --- ## SF6 leak detector URL: https://amperis.com/en/products/switch-testing/sf6/sf6-leak-detectors/sf6-leak-detector/ Category: [SF6 leak detectors for switchgear & GIS](https://amperis.com/en/products/switch-testing/sf6/sf6-leak-detectors/) Series: Detectores de Fugas SF6 datasheet: https://amperis.com/en/products/switch-testing/sf6/sf6-leak-detectors/sf6-leak-detector/SF6-GAS-LEAK-DETECTOR_EN.pdf > D-TEK Stratus: infrared SF₆ leak detector with ppm cloud hunting and pinpointing; EN 14624:2020, sensor life up to 2,000 h and 8-10 h battery.

TWR250B tests three-phase simultaneously up to 200 V AC or phase by phase up to 250 V AC, and measures winding resistance up to 25 A with the same connection, without a second instrument. **What turns ratio accuracy do I need?** IEC 60076-1 allows a deviation of ±0.5 % from the nameplate on every tap, so the tester must be considerably more accurate. TWR250B has ±0.03 % typical accuracy (±0.075 % guaranteed) at 250 V for ratios 0.8 to 999, more than six times better than that tolerance. **Which tests run without changing the leads?** All of them: resistance of all six windings, DVtest, demagnetization, turns ratio, phase shift and excitation current, with the same H and X cable connection. **Can it test single-phase transformers and CTs?** Yes. Single-phase units use two H and two X cables. On current transformers, the H cables go to the secondary and the X cables to the primary, or are slid through the core when there are no primary terminals. **Why demagnetize the core?** A DC test can leave residual magnetism that distorts other tests.

Modular system that watches every cell of the bank during capacity and charging tests **Supervising every cell voltage during a capacity or charging test of a stationary bank, and locating the cells or connections that fail, calls for a cell-by-cell monitoring system that records in real time.** BVS does it with modules spread along the bank and a control unit: cell voltage up to ±30 V with 1 mV resolution and ±(0.1 % of reading + 0.1 % of full scale) typical accuracy, inter-cell voltage up to ±50 mV with 1 µV resolution, string voltage up to ±600 V and sampling down to 1 s, with an LED alert on the module itself for every out-of-tolerance value. ### BVS key data - **Versions:** BVS, with one module per cell that also measures the inter-cell voltage; and BVS-4, with four cells per module, fewer modules and less wiring on large banks. - **Cell voltage:** ±30 V range, 1 mV resolution and ±(0.1 % of reading + 0.1 % of full scale) typical accuracy. - **Inter-cell voltage (BVS):** ±50 mV range, 1 µV resolution and ±(1 % of reading + 1 % of full scale) typical accuracy, to detect degraded connections. - **String:** optional SVM voltage module up to ±600 V (1 mV resolution, ±(0.1 % + 0.1 %) typical accuracy) and SCM clamp-based current module; with them BVS automates the capacity test with any load bank. - **Temperature and logging:** four ambient temperature channels on the control unit, optional cell temperature probe, internal 2 GB SD memory and sampling down to 1 s depending on the number of modules. - **Reliability:** internal RS485 bus where the failure of one module does not interrupt the others; LEDs on every module for out-of-tolerance values, so the degraded cell is bypassed without stopping the test. - **Connection and power:** USB or Bluetooth to PC; 90–264 V AC and 110 VA; 180 × 205 × 63 mm, 0.78 kg control unit. ### Advantages **Modular and scalable** A control unit powers and polls over RS485 the cell voltage modules spread along the bank; optional string voltage and string current modules complete the picture of the whole. **Two versions to match the bank** In the BVS version each module measures one cell — including the inter-cell voltage — and in the BVS-4 each module handles four cells, with fewer modules and less wiring. **Faults located instantly** Out-of-tolerance values are flagged with LEDs on the module itself, so the degraded cell is identified and bypassed without stopping the rest of the test. **Robust by design** The failure of one module does not interrupt the communication of the others, and the control unit adds four ambient temperature channels and an internal 2 GB SD memory. ### Applications - Capacity tests of stationary banks with cell-by-cell supervision. - Voltage monitoring during charging and recharging. - Detection of degraded cells and inter-cell connections. - Automated tests together with the discharge unit or any load bank. - Substations, UPS, telecom and power plants. ### About the product Cell voltage is measured up to ±30 V with 1 mV resolution; inter-cell voltage up to ±50 mV with 1 µV; and the optional modules reach ±600 V of string voltage. Data travels to the PC over USB or Bluetooth and the PC software presents it next to the discharge unit results in a single report. Accessories: CVM or CVM-4 cell voltage modules, SVM string voltage module, SCM string current module and optional cell temperature probes. ### Technical specifications Versions | BVS (1 cell per module); BVS-4 (4 cells per module) Cell voltage | ±30 V; 1 mV resolution Inter-cell voltage (BVS) | ±50 mV; 1 µV resolution String (optional modules) | ±600 V and clamp-based current Sampling | Down to 1 s, depending on the number of modules Communication | Internal RS485; USB or Bluetooth to PC Power supply | 90 – 264 V AC; 110 VA Control unit | 180 × 205 × 63 mm; 0.78 kg Typical accuracy (cell and string) | ±(0.1 % rdg + 0.1 % FS) on ±30 V and ±600 V Typical accuracy (inter-cell) | ±(1 % rdg + 1 % FS) on ±50 mV ### Frequently asked questions **How do you detect a weak cell during a battery bank capacity test?** By measuring the voltage of every cell throughout the discharge and comparing it with the tolerance. BVS records each cell up to ±30 V with 1 mV resolution and ±(0.1 % of reading + 0.1 % of full scale) typical accuracy, flags out-of-tolerance values with an LED on the module itself and lets the degraded cell be bypassed without stopping the test. **How are inter-cell connections checked during the discharge?** By measuring the voltage across each connection while the discharge current flows. In the BVS version each module measures the inter-cell voltage up to ±50 mV with 1 µV resolution and ±(1 % of reading + 1 % of full scale) typical accuracy, so a degraded connection stands out from the rest. **What is the difference between the BVS and the BVS-4?** The number of cells per module: one on the BVS, which also measures the inter-cell voltage, and four on the BVS-4, which simplifies installation on large banks. **Does it work with any discharge equipment?** Yes. With the optional string voltage and current modules, the system automates the capacity test with any load bank on the market. **What happens if a module fails mid-test?** Nothing beyond losing that measuring point: the communication of the remaining modules with the control unit continues uninterrupted. **How are faulty cells identified?** Each module flags out-of-tolerance values with LEDs and the software marks the cell, which can be safely bypassed during the discharge. **Does it measure temperature too?** Yes. The control unit offers four ambient temperature channels and the modules accept an optional cell temperature probe. --- ## CA Resistance Bank URL: https://amperis.com/en/products/battery-maintenance-and-charging/battery-dischargers/ca-resistance-bank/ Category: [Battery dischargers for capacity testing](https://amperis.com/en/products/battery-maintenance-and-charging/battery-dischargers/) Series: Battery Dischargers datasheet: https://amperis.com/en/products/battery-maintenance-and-charging/battery-dischargers/ca-resistance-bank/Brochure-AC-Load-Bank.pdf > Amperis AC load bank for testing UPS and AC power supplies: power factor from 0.8 to 1.0, 5 to 120 kW per element and local or remote control.

The 30x optical zoom of the visible channel helps identify the affected insulator or fitting from a distance. **What does combining the ultraviolet and thermal cameras provide?** It locates corona discharges and hot spots in the same image, giving more context on the cause of a fault without needing two separate inspections. **What temperature range does the thermal channel measure?** From -40°C to 160°C, with an NEdT sensitivity below 62.5 mK and 15 configurable colour palettes with isotherms. **Can the environmental context of each measurement be logged?** Yes, alongside the images and radiometric data, distance, air temperature and pressure, relative humidity and wind speed can be entered manually. **How are the three channels synchronised when zooming?** The visible channel's optical zoom is combined with the digital zoom of the ultraviolet and infrared channels, so all three keep the same framing. --- ## Distribution transformer tester ADOC-3 URL: https://amperis.com/en/products/transformers-testing/distribution-transformer-tester-adoc-3/ Category: [Transformers Testing](https://amperis.com/en/products/transformers-testing/) Series: Transformer Testing datasheet: https://amperis.com/en/products/transformers-testing/distribution-transformer-tester-adoc-3/Brochure-ADOC-3-Tester-English.pdf > ADOC-3: go/no-go tester that detects short-circuits and open circuits in distribution transformers from 1 kVA to 3 MVA in about 60 s. Go/no-go tester for distribution transformers from 1 kVA to 3 MVA **Knowing whether a distribution transformer can be re-energised after a storm or a line fault only takes a go/no-go tester that checks its windings de-energised and without disconnecting the secondary loads.** The ADOC-3 does it in a single test of about 60 seconds by contact on the primary bushings: it detects short-circuits and open circuits in the primary and short-circuits in the secondary of transformers from 1 kVA to 3 MVA and 1000 V to 50 kV, and shows the result as short-circuit, correct or open by LED and audible signal. ### ADOC-3 key data - **Diagnosis:** the ADOC-3 detects short-circuits and open circuits in the primary winding and short-circuits in the secondary, and classifies the transformer into three states — short-circuit, correct or open — with no numerical values to interpret. - **Transformer range:** 1 kVA to 3 MVA and 1000 V to 50 kV rated voltage, with single-phase, Delta or Yn primary: pole-mounted units, three-phase banks, pad-mount transformers and dry-type MV units. - **Measurement:** low voltage, AC and DC, across 3 channels by contact on the primary bushings, with the secondary loads connected; a single test of about 60 seconds covers all windings. - **Indication:** high-brightness LEDs and an audible signal for each of the three states. - **Reading reliability:** automatic self-test at power-on and a self-check mode for the integrity of the measurement leads. - **Power supply:** 4 alkaline AA batteries, 1.5 V, compatible with rechargeable NiMH batteries, for 8 hours of measurement; automatic shutdown after 15 minutes and a low-battery indicator. - **Ruggedness:** IP40 / IK06 enclosure with rubber boot, magnetic strap for fixing to the tank and an operating temperature of -20°C to +60°C. - **Size:** 177 × 89 × 45 mm and 0.47 kg, in a semi-rigid case; optional accessories: 1.5 m spare lead, 11 × 21 × 30 cm rigid case and elbow adapter pins. ### Advantages **Clear three-state diagnosis** The tester detects short-circuits and open circuits in the primary winding together with short-circuits in the secondary, and reports the result as short-circuit, correct or open through bright LEDs and an audible tone, with no waveform to interpret. **Testing without disconnecting the secondary** Measurement is taken by contact on the primary bushings while the secondary windings stay connected to their loads; a single test covers every winding, so a unit can be checked in roughly a minute. **Confidence before re-energising** After a line fault or a storm, the tester establishes whether a transformer can be reconnected without risking a violent failure once it is put back under load. **Coverage of every distribution layout** Three measurement channels handle single-phase transformers, three-phase banks, Yn and Delta couplings, pole-mounted units, pad-mount transformers and dry-type medium-voltage units, from 1000 V to 50 kV and 1 kVA to 3 MVA. **Compact and self-sufficient in the field** At 0.47 kg and 177 × 89 × 45 mm, the unit runs on four AA batteries for eight hours of measurement, checks the integrity of its own leads before each campaign and switches off automatically after 15 minutes of inactivity. ### Applications - Checking distribution transformers after a storm or a line fault, before re-closing. - Inspection campaigns on overhead networks and distribution substations. - Testing de-energised three-phase banks, pad-mount transformers and dry-type medium-voltage units. - Workshop receiving inspection before commissioning. ### About the product The IP40 enclosure, rated IK06 against impact, operates from -20°C to +60°C and is wrapped in a rubber boot that absorbs drops and splashes; a magnetic strap holds the unit against the transformer tank so the operator can work hands-free. The removable measurement leads store on a hook-and-loop strap and can be checked at any time using the built-in self-check mode, which flags a damaged cable before it causes a false reading. The complete kit ships in a semi-rigid case with the clip-ended leads, and a low-battery indicator combines with automatic shutdown to extend the life of the four AA cells. Available accessories: a spare 1.5 m measurement lead, a rigid transport case, and a set of adapter pins for transformer elbows. ### Technical specifications Detection | Short-circuit, correct, open circuit Primary configurations | Single-phase, Delta, Yn Rated transformer voltage | 1000 V to 50 kV Transformer power | 1 kVA to 3 MVA Measurement channels | 3 Power supply | 4 AA batteries; 8 hours of measurement Operating temperature | -20°C to +60°C Dimensions and weight | 177 × 89 × 45 mm; 0.47 kg Result indication | Audible and visual (high-brightness LED) Measurement type | Low voltage, AC and DC, by contact on the primary bushings Protection ratings | IP40; IK06 ### Frequently asked questions **Which transformer voltages and power ratings does the ADOC-3 cover?** The ADOC-3 tests de-energised distribution transformers from 1 kVA to 3 MVA and 1000 V to 50 kV rated voltage, with single-phase, Delta or Yn primary; it covers pole-mounted units, three-phase banks, pad-mount transformers and dry-type MV units. **Does the ADOC-3 run on rechargeable batteries, and how long do they last?** Yes. The ADOC-3 is powered by 4 alkaline AA 1.5 V batteries and is compatible with rechargeable NiMH batteries; it provides 8 hours of measurement, switches off by itself after 15 minutes of inactivity and warns with a low-battery indicator. **Do the secondary loads need to be disconnected before the test?** No. The ADOC-3 measures with the secondary windings still connected to their loads; only contact with the primary bushings is required. **What does a go/no-go result mean?** The tester does not output a value to interpret. It classifies the transformer into one of three states — short-circuit, correct or open circuit — shown by LED and confirmed by an audible signal. **Does it work on three-phase banks?** Yes. Its three channels cover single-phase transformers as well as three-phase banks in Yn or Delta coupling, including pad-mount units. **How is the condition of the measurement leads verified?** A built-in self-check mode confirms the integrity of the leads before the test, which prevents a false diagnosis caused by a damaged cable. **How long does a check take?** About 60 seconds: a single test verifies every winding and the transformer's status is displayed immediately. --- ## Nexus 1450 Power Quality Meter URL: https://amperis.com/en/products/electric-panel-multimeters/serie-nexus/nexus-1450/ Category: [Nexus Series: power quality meters](https://amperis.com/en/products/electric-panel-multimeters/serie-nexus/) Series: Serie NEXUS datasheet: https://amperis.com/en/products/electric-panel-multimeters/serie-nexus/nexus-1450/Brochure-Nexus-1450-EN.pdf > Nexus 1450: class A power quality meter (IEC 61000-4-30) and 0.06 % class 0.2S revenue meter, with a transducer base that replaces the 125x series. Class A power quality meter with transducer base and separate display, 0.06 % energy accuracy **Upgrading the metering of an installed switchboard without cutting the panel door, while obtaining revenue-grade energy and class A power quality data to IEC 61000-4-30, calls for a meter with a transducer base and separate display.** The Nexus 1450 is a direct physical retrofit of the 125x series meters, measures energy to 0.06 % (ANSI C12.20 class 0.1 and IEC 62053-22 class 0.2S) thanks to two sensing stages on every current input, analyses harmonics to the 511th order, records waveforms at 1024 samples per cycle and communicates simultaneously over four RS-485 and two Ethernet ports with Modbus, DNP3 and IEC 61850. ### Nexus 1450 key data - **Revenue accuracy:** the Nexus 1450 measures energy to 0.06 % of reading from 0.025 to 20 A at unity power factor and meets ANSI C12.20-2015 class 0.1 and IEC 62053-22 class 0.2S; pick-up starts at 1 mA and full accuracy is reached at 25 mA, with 1 A or 5 A CTs on the same input (classes 2 and 20). - **Accuracy per quantity:** voltage and current to 0.04 % of reading, neutral current to 0.1 %, frequency to 0.001 Hz, active and apparent power to 0.06 %, reactive power and power factor to 0.15 % and THD to 2.5 % of reading. - **Power quality:** IEC 61000-4-30 class A edition 3, third-party certified; harmonics and interharmonics to IEC 61000-4-7 class A up to the 511th order (real-time magnitude and angle to the 127th); flicker to IEC 61000-4-15 class A on 230 V / 50 Hz and 120 V / 60 Hz systems; weekly EN 50160 reports and ITIC/CBEMA and SEMI F47 plots. - **Logging:** waveforms at 512 samples per cycle (V1) or 1024 (V2) with 16-bit conversion and fault capture up to eight times full scale; internal database with 172 parameters, eight historical logs of 64 channels and 512 MB (V1) or 1200 MB (V2) of logging memory. - **Communications:** six standard ports working simultaneously: four RS-485 (one selectable to RS-232, with RTU master capability) up to 115,200 bit/s and two independent Ethernet ports, RJ45 10/100BaseT and ST-terminated 100Base-FX fibre; Modbus RTU/ASCII/TCP, DNP3 level 2, HTTPS and SNTP, plus IEC 61850 with GOOSE on version V2. - **Measuring inputs:** 20 to 720 V AC between any voltage inputs, isolated to 2500 V AC; fault current recording up to ±80 A peak; nominal frequency from 42.5 to 69.5 Hz and wideband measurement from 20 to 500 Hz. - **Installation:** IP30 transducer base with LED display or 4.3″ colour touchscreen (IP65), eight status inputs up to 150 V DC, auxiliary voltage input, two pulse outputs, 96–276 V AC/DC or 18–60 V DC supply and operation from -25 to +70 °C. ### Advantages **Two sensing stages on every current input** Each current input carries a high gain sensor and a low gain sensor that measure the signal from the external current transformers at the same time. The meter reads the signal level and chooses the optimal sensing circuit, which holds 0.06 % accuracy across an extended measuring range; pick-up starts at 1 mA and full accuracy is reached at 25 mA, so the same meter serves 5 A and 1 A secondary current transformers. #### Advanced energy metering - Full four-quadrant metering with maximum and minimum recording and time stamp. - Transformer and line loss compensation for iron, copper and total substation losses. - Coincidental readings, such as power factor or reactive power at the time of peak demand. - Load aggregation through pulse inputs, including gas and water commodities. #### Built for retrofit - The transducer base is a direct physical retrofit of the previous 125x series meters. - The separate display mounts into existing analogue meter knockouts. - Eight built-in digital status inputs, an auxiliary voltage input and two pulse outputs as standard. ### Applications - Direct replacement of analogue 125x series meters in installed switchboards. - Power quality measurement in substations and industrial distribution panels. - Reliability studies: sags, swells, harmonics and unbalance. - Integration into SCADA systems through DNP3, Modbus or redundant Ethernet links. ### About the product Accuracy holds from the bottom of the range to full scale, well inside the ANSI C12.20 and IEC 62053-22 limit lines, because the two sensing stages keep the error flat where single-stage meters lose accuracy. The meter carries an internal time reference accurate to 20 ppm and supports line frequency, DNP3, IRIG-B or SNTP synchronisation; nominal frequency range is 42.5 to 69.5 Hz, with additional wideband measurement from 20 to 500 Hz. Voltage anomalies, harmonics, flicker, unbalance and other indices are measured to the class A specification, which makes the readings comparable between instruments and admissible in contractual disputes. It analyses harmonics and interharmonics to the 511th order and produces weekly EN 50160 power quality reports, together with ITIC/CBEMA and SEMI F47 plots for voltage events. Waveforms are captured at up to 1024 samples per cycle with 16-bit conversion, backed by an internal database that automatically logs 172 parameters and up to 4 GB of available memory. ### Technical specifications Energy accuracy | 0.06 %; pick-up at 1 mA, full accuracy at 25 mA Power quality measurement | IEC 61000-4-30 class A edition 3 Harmonics and flicker | IEC 61000-4-7 and IEC 61000-4-15, to the 511th order Waveform recording | Up to 1024 samples/cycle, 16-bit conversion Memory | Up to 4 GB, with 1.2 GB reserved for logging Communications | 6 ports: 4 RS-485 (one selectable to RS-232) and 2 Ethernet (RJ45 and fibre optic) Time synchronisation | Line frequency, DNP3, IRIG-B, SNTP Frequency range | 42.5-69.5 Hz nominal; wideband 20-500 Hz Accuracy class | ANSI C12.20-2015 class 0.1; IEC 62053-22 class 0.2S Measuring inputs | 20–720 V AC between inputs; 1 A and 5 A CTs on the same input; 1 mA pick-up Protocols | Modbus RTU/ASCII/TCP, DNP3 level 2, IEC 61850 with GOOSE (V2), HTTPS, SNTP ### Frequently asked questions **What is the difference between the Nexus 1450 V1 and V2 versions?** V1 records waveforms at 512 samples per cycle with 512 MB of logging memory; V2 raises this to 1024 samples per cycle and 1200 MB, and adds the IEC 61850 server with GOOSE messaging and cross-triggering for distributed fault recording.

Resolution reaches 0.1 µΩ over a range of 0.1 µΩ to 3000 mΩ. **How do the two sub-series differ?** In output voltage and cabling: RMO-H1/H2/H3 use a 1-cell battery (4.2 V) with short leads, while RMO-H21/H22/H23 use two cells (8.4 V) for leads of 5 m or longer. The lead sets are not interchangeable between sub-series. **What is the advantage of the Li-Po battery over an ultra-capacitor?** There is no waiting for a charge between tests and the current does not depend on the load: you select the exact value and it stays stable during the measurement. **Can it measure with the breaker grounded on both sides?** Yes. The BSG test uses the same connection as with one side grounded; bear in mind that part of the current flows through the groundings, so the reading may be slightly less accurate. **How are results transferred to the computer?** Over Bluetooth: the included PC software downloads the stored measurements, analyses them and exports reports in several formats. --- ## RMO-TT Series: winding resistance meter URL: https://amperis.com/en/products/transformers-testing/winding-ohmmeters/rom-tt-series/ Category: [Transformer winding ohmmeters](https://amperis.com/en/products/transformers-testing/winding-ohmmeters/) Series: Transformer winding resistance meters datasheet: https://amperis.com/en/products/transformers-testing/winding-ohmmeters/rom-tt-series/Catalogo-RMO-TT-EN.pdf > RMO-TT: winding resistance up to 100 A DC, ±(0.1% rdg + 0.1% FS), 0.1 ms tap changer DVtest, vibration with a ±50 g accelerometer and four Pt100 channels.

RMO-TT records the DVtest with 0.1 ms sampling and, with a ±50 g ICP accelerometer fixed to the external tank, the vibration signature of every operation, plus the motor current, all in the same test and with built-in OLTC control. **How accurate is RMO-TT for winding resistance?** Typical accuracy is ±(0.1% of reading + 0.1% of full scale) from 0.1 µΩ to 1.999 kΩ, ±(0.2% + 0.1%) from 2 to 9.999 kΩ and ±(1% + 1%) from 10 to 99.99 kΩ. Guaranteed accuracy is ±(0.2% + 0.2%) up to 9.999 kΩ and ±(2.5% + 2.5%) above, with up to 100 A DC on RMO100TT. **What does the vibration measurement add?** A non-intrusive diagnostic path: the accelerometer fixed to the external tap changer tank records the mechanical signature of every operation, reveals looseness or wear and verifies the operating time without opening the tap changer. **When is the 100 A model worthwhile?** On large transformers with very low resistances, where a high current stabilises the reading sooner; it is the only portable of the series reaching 100 A DC. **Can the complete tap changer test run automatically?** Yes. The built-in control unit changes the taps and the software chains measurement and switching through every position without operator intervention. **How does it differ from the RMO-TD?** It shares the DVtest and the OLTC control, but adds the vibration channel, four temperature channels instead of one and the 100 A model. **How is the transformer left after the test?** Demagnetized: the device applies alternating current of decreasing magnitude generated by polarity reversal until the remanent flux is cancelled. --- ## SF6 gas transfer unit AGTU URL: https://amperis.com/en/products/switch-testing/sf6/sf6-gas-servicing-equipment/sf6-gas-transfer-unit-agtu/ Category: [SF6 gas recovery & handling equipment](https://amperis.com/en/products/switch-testing/sf6/sf6-gas-servicing-equipment/) Series: Equipos de manipulación de SF6 datasheet: https://amperis.com/en/products/switch-testing/sf6/sf6-gas-servicing-equipment/sf6-gas-transfer-unit-agtu/AGTU_eng.pdf > AGTU: recovers, consolidates and transfers SF₆ up to 69 kV with a 34 bar oil-less compressor, 2 m³/h and 0.1 µm filtration in a 34 kg steel unit.

High-voltage circuit breaker monitoring: Smart Capture diagnostics, SF6 gas surveillance and contact wear detection on a single modular platform **Continuous monitoring of a high-voltage circuit breaker calls for a monitor that diagnoses every operation, tracks contact wear and trip coil integrity and watches the insulating gas, without touching the mechanism.** The BPM does this with non-intrusive sensing: it compares the waveform of every open and close with the first-trip baseline (Smart Capture), accumulates the I²T of each operation, identifies whether trip coil 1 or 2 operated, with its current and the interrupting time, and measures the density, temperature and humidity of the SF6 or dry air, with leakage-rate and time-till-lockout alarms. It is installed in the breaker's own cabinet and operates from -40 to +70°C. ### BPM key data - **Diagnostics per operation:** Smart Capture compares every BPM-recorded open and close with the first-trip baseline: open, close and arcing times, latch and bearing performance, lubrication, A/B auxiliary contacts and fault current. - **Trip coils:** the BPM monitors the circuit resistance of up to three trip coils, identifies whether coil 1 or coil 2 tripped and logs its peak and maximum current and the interrupting time, with printable graphs and tables. - **Contact wear:** cumulative I²T per operation and counters of total and faulted operations, so internal inspections are scheduled only when needed. - **Insulating gas:** SF6 or dry air, on breakers with one, two or three gas systems; density, temperature and humidity, with alarms for leakage rate, time-till-lockout trend and mass gas loss. - **Charging motor and heaters:** motor starts, current and runtime, adapting to hydraulic fluid viscosity in cold weather; heater current and voltage, and ambient, cabinet and gas temperatures. - **Configuration:** the BPM is ordered for a ganged operating system (four preset expansion cards) or an independent pole operating system (nine cards: seven preset and two optional), in a 4-slot or 9-slot frame. - **Communications and environment:** DNP3, Modbus and IEC 61850 over copper or fibre Ethernet, with 2 or 3 RS-485 ports and optional RS-232 or serial fibre; 110-240 VAC (50-60 Hz) or 110-250 VDC; -40 to +70°C. ### Advantages **Smart Capture diagnostics on every operation** Graphically compares each operation with the first-trip baseline: opening and closing times, latch and bearing performance, lubrication, auxiliary contacts and fault current. **Contact wear tracked through cumulative I²T** Cumulative I²T calculations schedule internal inspections only when needed, cutting the cost and labour of time-based cyclic maintenance. **SF6 and dry-air gas surveillance** Multi-parameter sensors measure density, temperature and humidity, with alarms for leakage rate, time-till-lockout trend and mass gas loss. **Charging motor monitoring built for cold weather** Logs motor starts, current and runtime, and adapts to changes in hydraulic fluid viscosity and to humidity in pneumatic systems. ### Applications - Predictive and condition-based maintenance for high-voltage circuit breakers. - Reduced SF6 leakage and environmental protection. - Breakers with frequent operations, such as switching between generation and the grid. - Cold-weather sites. ### About the product Configured with only the modules needed, in a 4-slot or 9-slot frame, it combines waveform capture, SF6/dry-air surveillance, trip coil and charging motor condition, cabinet heater monitoring and ambient temperature. It identifies which coil — 1 or 2 — operated, its current and the interrupting time, with an operation counter and printable graphs. A desktop application is included for engineers to view data and run diagnostics; an upgradable fleet edition aggregates data from every monitor to analyse maintenance trends. Available accessories: optional partial-discharge monitoring module and additional thermal sensors. ### Technical specifications Diagnostics | Smart Capture: waveform vs. first-trip baseline; timings, latch, bearing and fault current Trip coil and contacts | Identifies the coil that operated (1 or 2), its current and resistance; cumulative I²T Operations | Operation counter and interrupting time, with printable graphs Charging motor | Starts, current and runtime; cold-weather adaptation Insulating gases | SF6/dry air: density, temperature, humidity; leakage alarms Heaters and environment | Cabinet heater current and voltage; ambient, cabinet and gas temperature Communications | DNP3, Modbus and IEC 61850 over copper/fibre Ethernet Power supply and temperature | 110-240 VAC or 110-250 VDC; -40 to +70°C Chassis, by slot count | 4-slot: 248 × 126 mm (212 mm between lower reference lines), 143 mm depth · 9-slot: 375 × 126 mm (339 mm between lower reference lines), 143 mm depth Ordering configuration | Ganged operating system: 4 preset cards · Independent pole operation: 9 cards (7 preset and 2 optional) Gas and trip coils | Breakers with 1, 2 or 3 SF6 gas systems; integrity of up to 3 trip coils Serial ports | 2 RS-485, plus an optional third RS-485, RS-232 or serial fibre ### Frequently asked questions **Can the BPM provide evidence that each trip coil works?** Yes. On every operation the BPM logs whether the trip was initiated through trip coil 1 or trip coil 2, the current drawn by that coil and the interrupting time, and keeps it in printable graphs and tables. That is the evidence NERC requirements ask for, as they require breakers to be tested at least every six years to verify that they interrupt through each of their trip coils. **What does the BPM add to periodic breaker testing?** Breakers sit idle for long periods, which breaks down lubrication and corrodes contacts, and cyclic tests do not always reproduce those conditions. The BPM analyses every real operation and continuously monitors the charging motor, trip coils, heaters and gas, so it detects a stored-energy system failure before the breaker is called on to operate, information that protective relays cannot provide. **What is Smart Capture technology?** A waveform analysis that compares each operation with the first-trip baseline. **How does it detect contact wear?** Through cumulative I²T calculations and identification of the trip coil that operated. **Which gases does it monitor?** SF6 and dry air, with alarms for leakage rate and time-till-lockout trend. **Is it suited to cold climates?** Yes, it adapts to changes in hydraulic viscosity and to humidity in pneumatic systems. **Can it manage several breakers at once?** Yes, through an upgradable fleet-management application that aggregates data from every monitor.

Lightweight, rugged cart to evacuate and refill SF6 equipment in the field **Before a switchgear or circuit-breaker compartment is filled with SF6, air and moisture must be removed by vacuum, and the gas must then be admitted from the cylinder at regulated pressure.** The ARFU-2 performs both operations from a 31 kg cart: its permanently mounted 17 m³/h (10 CFM) vacuum pump reaches a sealed pressure below 0.03 mbar, and the same 3-way ball valve then connects the standard SF6 cylinder through an adjustable pressure regulator, with an integral vacuum gauge to follow the process. ### ARFU-2 key data - **Function:** the ARFU-2 evacuates air and moisture from switchgear and circuit-breaker compartments and regulates their subsequent filling from standard SF6 cylinders. - **Vacuum:** the ARFU-2's high-capacity, permanently mounted vacuum pump displaces 17 m³/h (10 CFM) and reaches a sealed pressure below 0.03 mbar. - **Operation:** the ARFU-2 switches from evacuation to filling with a single 3-way ball valve, without changing hoses. - **Filling:** the user sets the ARFU-2's filling pressure with a pressure regulator and follows the process on the integral vacuum gauge. - **Transport:** the ARFU-2 weighs 31 kg, measures 1500 × 600 × 400 mm and rides on large tires for moving over substation gravel. - **Power and supply:** the ARFU-2 runs on 120 V, 60 Hz or 220 V, 50/60 Hz, single-phase (other voltages on request), and ships with 3 m hoses and a power cable. ### Advantages **Two operations, one cart** The ARFU-2 brings together prior evacuation of air and moisture and subsequent regulated refilling in a single unit, avoiding the need to bring two separate units to site. **Single-valve operation** A 3-way ball valve switches between evacuation and refilling without rewiring hoses, simplifying operation in the field. **High-capacity vacuum pump** The permanently mounted vacuum pump reaches a sealed pressure below 0.03 mbar, leaving the compartment ready for refilling. **Regulated, controlled refilling** Refilling is user-adjustable through a pressure regulator, with an integral vacuum gauge to track every stage of the process. **Built for substation work** The lightweight yet rugged frame rides on large tires that make it easy to move over gravel yards or uneven ground. ### Applications - Evacuation of air and moisture prior to filling SF6 equipment. - Regulated filling of switchgear and circuit-breaker compartments with SF6. - Field commissioning and maintenance of gas-insulated equipment. - Monitoring of vacuum and filling pressure through integral gauges. ### About the product The process runs in two stages linked by the same 3-way valve: the compartment is first evacuated with the vacuum pump until free of air and moisture, down to a sealed pressure below 0.03 mbar; the same valve then connects the SF6 cylinder to the equipment through the pressure regulator, which controls the filling pressure while the vacuum gauge is used to follow the process. The cart runs on 120 V or 220 V single-phase power and ships with 3 m hoses and a power cable. Available accessories: special supply voltages on request and longer hoses for hard-to-reach installations. ### Technical specifications Vacuum pump | 10 CFM (17 m³/h) Sealed vacuum | Below 0.03 mbar Valve | 3-way ball valve, evacuation/filling Filling | User-regulated through pressure regulator Power supply | 120 V AC, 60 Hz / 220 V AC, 50/60 Hz, single-phase Dimensions (H × W × D) | 1500 × 600 × 400 mm Weight | 31 kg Hoses | 3 m, supplied with power cable Indication | Integral vacuum gauge Frame | Lightweight and rugged, with large-diameter tires for gravel ### Frequently asked questions **Does the ARFU-2 recover SF6 from the equipment?** No. The ARFU-2 is designed for two functions: evacuating the compartment, with its 17 m³/h pump down to below 0.03 mbar, and regulating filling from standard SF6 cylinders. Gas recovery is done with an SF6 recovery unit. **How heavy and how large is the ARFU-2?** The ARFU-2 weighs 31 kg and measures 1500 × 600 × 400 mm (H × W × D); it runs on 120 V or 220 V single-phase and moves on large-diameter tires. **What two operations does the ARFU-2 perform?** It evacuates air and moisture from the compartment before filling, then regulates the filling of SF6 from standard cylinders. **How do you switch between evacuation and filling?** With a single 3-way ball valve, with no need to rewire hoses. **What vacuum level does it reach before filling?** The vacuum pump reaches a sealed pressure below 0.03 mbar. **Is it suited to substation work on uneven ground?** Yes. Its lightweight, rugged frame rides on large tires designed for gravel and uneven surfaces. **Who regulates the filling pressure?** The user, through a pressure regulator, using the integral vacuum gauge as a reference. --- ## Rapidox 5100: multigas analyser URL: https://amperis.com/en/products/switch-testing/sf6/gas-analysers/multigas-analyser-rapidox-5100/ Category: [SF6 gas analysers: purity, moisture, SO2](https://amperis.com/en/products/switch-testing/sf6/gas-analysers/) Series: Gas analysers datasheet: https://amperis.com/en/products/switch-testing/sf6/gas-analysers/multigas-analyser-rapidox-5100/Brochure-Rapidox-5100-MultiGas-EN.pdf > Rapidox 5100: portable multigas analyser for up to 6 gases (CH₄, CO₂, O₂, H₂S…) with calorific value, 2-4 min measurement, IP66 case and 8 h+ battery.

With sources above atmospheric pressure the pump is deactivated and the gas flows through the analyser, with the flow regulated by a rotary knob. **How is the data retrieved?** Logging is continuous; Excel-compatible files are downloaded via a USB memory stick, and the integrated thermal printer provides results on demand. --- ## RMO-TW Series: winding resistance meter URL: https://amperis.com/en/products/transformers-testing/winding-ohmmeters/rmo-tw-series/ Category: [Transformer winding ohmmeters](https://amperis.com/en/products/transformers-testing/winding-ohmmeters/) Series: Transformer winding resistance meters datasheet: https://amperis.com/en/products/transformers-testing/winding-ohmmeters/rmo-tw-series/Catalogo-RMO-TW-EN.pdf > RMO-TW: 10 to 50 A DC winding ohmmeter at 55 V weighing 8 kg, three channels, ±(0.1% rdg + 0.1% FS), tap changer verification and demagnetization. The essential winding ohmmeter: three channels, 55 V output and only 8 kg **Measuring the winding resistance of transformers, motors and generators without carrying a heavy instrument only takes a three-channel ohmmeter with ripple-free DC current, automatic discharge and tap changer verification.** The RMO-TW series offers this in an 8 to 8.5 kg metal case: 5 mA to 50 A DC depending on model at up to 55 V DC, a 0.1 µΩ to 100 kΩ range with ±(0.1% of reading + 0.1% of full scale) typical accuracy up to 2 kΩ, three windings in series measured at once and detection of tap changer interruptions with 4 ms sampling. ### RMO-TW key data - **Models and current:** RMO10TW, RMO20TW, RMO30TW and RMO50TW, with 10, 20, 30 or 50 A DC maximum and 500, 750, 850 or 1000 W output; all four inject at up to 55 V DC. - **Resistance accuracy:** RMO-TW measures from 0.1 µΩ to 100 kΩ with ±(0.1% rdg + 0.1% FS) typical up to 1.999 kΩ, ±(0.2% + 0.1% FS) from 2 to 9.999 kΩ and ±(1% + 1% FS) from 10 to 99.99 kΩ; guaranteed, ±(0.2% + 0.2% FS) up to 9.999 kΩ; best resolution 0.1 µΩ. - **Three measuring channels:** RMO-TW tests primary, secondary and tertiary windings connected in series at once, or the three phases of a motor or generator stator. - **Tap changer:** it measures at every position without discharging between taps, detects current interruptions with 4 ms sampling and has a dedicated mode for de-energized tap changers (DETC). - **Discharge and demagnetization:** automatic discharge circuit at the end of each measurement and demagnetization by polarity reversal with decreasing magnitude. - **Temperature and data:** Pt100 channel from -50 to +180 °C, 1000-measurement memory (5000 optional), USB as standard with optional RS232 and Bluetooth. - **Portable:** RMO-TW measures 198 × 250 × 350 mm, weighs 8 to 8.5 kg and runs on 90–264 V AC, 50/60 Hz (2250 VA). ### Advantages **Three windings in a single measurement** The independent channels test primary, secondary and tertiary windings connected in series at once; saturating the core through the winding with the most turns shortens stabilisation and the whole test. **Tap changer verification** Resistance is measured at every tap position without discharging between taps: if the current is interrupted during switching, the device detects it and warns the operator. **De-energized taps too (DETC)** A dedicated mode walks through the positions of de-energized tap changers within the same test, with criteria separate from on-load tap changers. **Automatic discharge and demagnetization** The discharge circuit governs the stored energy at the end of the measurement, and demagnetization removes remanent magnetism by reversing polarity with decreasing magnitude. ### Applications - Winding resistance of power and distribution transformers and autotransformers. - Verification of on-load and de-energized tap changers. - Rotating machines: motor and generator stators through the three channels. - Non-inductive resistive objects: busbars, splices and joints. - Heat Run test with resistance and temperature extrapolation. ### About the product The measuring range spans 0.1 µΩ to 100 kΩ with a typical accuracy of ±(0.1% of reading + 0.1% of full scale) up to 2 kΩ and a best resolution of 0.1 µΩ; a Pt100 channel measures temperature from -50 to +180 °C. The memory keeps 1000 measurements (5000 optional) and the PC software controls the test over USB and exports reports to Excel, PDF or Word. Accessories: current and sense cables with TTA clamps, temperature probes, verification shunt, Bluetooth module, optional built-in thermal printer, bags and transport cases with or without wheels. ### Technical specifications Models | RMO10TW, RMO20TW, RMO30TW and RMO50TW Test current | 5 mA – 50 A DC depending on model Output voltage | Up to 55 V DC Measuring range | 0.1 µΩ – 100 kΩ Typical accuracy | ±(0.1% rdg + 0.1% FS) up to 2 kΩ OLTC verification | 4 ms sampling Power supply | 90 – 264 V AC, 50/60 Hz; 2250 VA Dimensions and weight | 198 × 250 × 350 mm; 8 – 8.5 kg Typical accuracy from 2 to 100 kΩ | ±(0.2% rdg + 0.1% FS) from 2 to 9.999 kΩ; ±(1% rdg + 1% FS) from 10 to 99.99 kΩ Guaranteed accuracy | ±(0.2% rdg + 0.2% FS) from 0.1 µΩ to 9.999 kΩ; ±(2.5% rdg + 2.5% FS) from 10 to 99.99 kΩ ### Frequently asked questions **Which lightweight winding resistance meter suits transformers, motors and generators?** A three-channel unit with enough current and automatic discharge. RMO-TW weighs 8 to 8.5 kg, delivers 5 mA to 50 A DC at up to 55 V DC and measures three windings in series or the three phases of a stator at once; the 10 A RMO10TW covers small machines and the 50 A, 1000 W RMO50TW the higher-power transformers. **How accurate is RMO-TW for winding resistance?** Typical accuracy is ±(0.1% of reading + 0.1% of full scale) from 0.1 µΩ to 1.999 kΩ, ±(0.2% + 0.1%) from 2 to 9.999 kΩ and ±(1% + 1%) from 10 to 99.99 kΩ. Guaranteed accuracy is ±(0.2% + 0.2%) up to 9.999 kΩ and ±(2.5% + 2.5%) above, on all four models. **Which model should I choose?** It depends on the transformer size: the higher the power and the lower the winding resistance, the more current helps; the RMO50TW reaches 50 A with 1000 W of output and the RMO10TW covers small machines with 10 A. **How does it differ from the RMO-TD series?** The RMO-TW verifies the tap changer by detecting interruptions with 4 ms sampling, but it lacks the 0.1 ms DVtest dynamic analysis, the motor current channel and the OLTC control unit of the RMO-TD. **Does it measure rotating machines?** Yes. By connecting the three stator phases in series, the three channels measure the three resistances in one go. **How does it handle the energy stored in the winding?** The automatic discharge circuit dissipates it in a controlled way after each measurement, before the wiring is touched. **What PC interface does it offer?** USB as standard, with optional RS232 and Bluetooth; the included software plots the results and assembles the reports. --- ## Ultrasonic inspection system PULD 40 URL: https://amperis.com/en/products/partial-discharge-detector/puld-40/ Category: [Partial Discharge Detection](https://amperis.com/en/products/partial-discharge-detector/) Series: Partial Discharge Detector datasheet: https://amperis.com/en/products/partial-discharge-detector/puld-40/Brochure-PULD-40.pdf > PULD-40: 40 kHz ultrasonic detector (38-48 kHz, 96 dB) for corona, arcing and leaks, with laser-sighted parabolic sensor for 15 m, 528 g and 4 h battery.

Portable analyser for SF6 purity, moisture and decomposition products **Verifying SF6 quality on site in medium- and high-voltage switchgear and circuit breakers calls for a portable analyser that measures purity, moisture and decomposition products together, compares the result with IEC and CIGRE criteria and releases no gas to atmosphere.** The Rapidox 6100 Portable measures up to eight gases simultaneously: SF6 purity from 0 to 100 % with ±0.5 %, dew point from −60 to +20 °C with ±2 °C, and SO2, HF, H2S and CO with ±2 % of full scale. It shows PASS or FAIL against the selected test, captures the sampled gas in a recovery bag and weighs 8.5 kg in its IP66 case with over 8 h of battery life. ### Rapidox 6100 Portable key data - **SF6 purity:** 0-100 % infrared sensor with ±0.5 % accuracy, 12-month calibration interval and a life span of more than 5 years. - **Moisture:** polymer dew-point sensor from −60 to +20 °C (10-24,000 ppmV) with ±2 °C of reading, correctable to room temperature or 20 °C; the Rapidri system keeps it dry with molecular sieve, and the sensor goes from wet to −60 °C in under 10 min. - **Decomposition products:** SO2 0-100 or 0-500 ppm, HF 0-10 or 0-30 ppm, H2S 0-100 ppm and CO 0-1,000 ppm, with electrochemical sensors of ±2 % of full scale. - **Mixtures:** CF4 from 0 to 80 % (±1 % of reading), calculated by balance of the SF6 and air readings, and air/N2 from 0 to 100 %; up to eight gases in one instrument. - **Standard tests:** pre-loaded IEC and CIGRE configurations, including IEC 60480 > 200 kPa, with PASS or FAIL shown on screen and printed, plus custom tests. - **Sampling:** continuous or timed mode from 2 to 8 min (minimum 6 min with H2O), 100-1,000 ml/min flow, inlet pressure from 0.3 to 10 bar and an optional pump for gas below 0.5 bar. - **Zero emissions:** the outlet nozzle connects to the gas recovery bag, which captures all the sampled SF6. - **In the field:** 8.5 kg IP66 case, lithium battery for over 8 h charging at 90-260 V AC, 4 GB of logging (approx. one year), thermal printer and operation from −10 to +40 °C; CE marked to EN 61010-1 and EN 61326-1. ### Advantages **Straightforward operation with results in minutes** Test set-up and start are handled from the 7″ (18 cm) colour touch screen, with soft menu keys and an alphanumeric keypad. All selected gases are measured and logged simultaneously, and a stable reading is obtained within a few minutes. **Up to eight gases with a single instrument** The modular architecture supports simultaneous analysis of up to eight compatible gases: SF6, H2O (dew point), SO2, HF, CF4, H2S, CO and O2/N2 (air), depending on the requested configuration. SF6 purity is measured with an infrared sensor over 0-100 % with ±0.5 % accuracy. **Testing without gas emissions** The gas outlet nozzle allows the analyser to be coupled to a recovery bag, so the sampled gas is captured in full rather than released to the atmosphere. **Faster moisture readings** Units equipped with an H2O sensor incorporate the Rapidri drying system, which reduces the waiting time between successive dew-point readings. A dedicated valve isolates the sensor when the instrument is not in use. **Standardised tests as delivered** Current IEC and CIGRE test configurations come pre-installed and custom parameters can be defined. Results are printed on site with the integrated thermal printer or exported in MS Excel-compatible format via USB memory stick. ### Applications - Maintenance of GIS cells and circuit breakers in MV and HV substations. - Commissioning and acceptance testing of electrical equipment to IEC and CIGRE criteria. - Zero-loss sampling in installations where the analysed gas must be recovered. ### About the product The internal pressure of the sample is recorded together with the readings, and test locations and user names are editable, with password protection.

The Rapidox 6100 Portable measures SF6 from 0 to 100 % with ±0.5 %, dew point from −60 to +20 °C with ±2 °C and SO2, HF, H2S and CO with ±2 % of full scale, and with the pre-loaded IEC 60480 > 200 kPa test it displays and prints PASS or FAIL; it weighs 8.5 kg in its IP66 case. **How long does a test take and when is the pump needed?** In timed mode the Rapidox 6100 Portable samples for 2 to 8 min, with a minimum of 6 min when moisture is measured. With pressurised gas from the compartment it is enough to set the flow; the pump is only needed when the SF6 pressure is below 0.5 bar. The inlet accepts 0.3 to 10 bar. **Why does SF6 need to be analysed periodically?** SF6 is a greenhouse gas that must remain within a closed circuit. Early detection of moisture and decomposition products prevents outages and failures and reduces maintenance costs. **Is any gas lost during the test?** No. The analyser couples to a recovery bag that captures all the sampled gas. **Which test standards are included?** Current IEC and CIGRE configurations come pre-installed; custom tests can also be defined. **How are results documented?** Via the integrated thermal printer or by export to MS Excel-compatible format on a USB memory stick. --- ## Rapidox 6100 Pump Back: SF6 analyser URL: https://amperis.com/en/products/switch-testing/sf6/gas-analysers/pump-back-gas-analyser/ Category: [SF6 gas analysers: purity, moisture, SO2](https://amperis.com/en/products/switch-testing/sf6/gas-analysers/) Series: Gas analysers datasheet: https://amperis.com/en/products/switch-testing/sf6/gas-analysers/pump-back-gas-analyser/Brochure-Rapidox-6100-Pump-Back-Gas-EN.pdf > Rapidox 6100 Pump Back: automatic SF₆ analyser that returns the gas with a 10 bar compressor; inlet up to 35 bar, ±0.5 % purity and up to 8 gases. Fully automatic SF6 analyser with gas return and zero emissions **Analysing the SF6 in high-voltage circuit breakers, switchgear and transformers without releasing gas or emptying recovery bags afterwards calls for an analyser that takes the sample, measures it and returns it to the equipment automatically.** The Rapidox 6100 Pump Back accepts inlet pressures from 0.3 to 35 bar, vacuum-purges the line, measures up to eight gases at once, with SF6 purity from 0 to 100 % and ±0.5 %, in 2, 4, 6 or 8 min, and when finished pumps the dried gas back into the compartment with a battery-powered compressor of up to 10 bar, with up to 15 pump-back cycles per charge. ### Rapidox 6100 Pump Back key data - **Gas return:** compressor up to 10 bar with up to 15 cycles per battery charge; the internal storage bag allows up to five tests before a pump-back, and desiccant moisture traps dry the gas before it is returned. - **Sampling:** automatic or manual with inlet pressure sensing from 0.3 to 35 bar (gauge), vacuum line purge, 0.5 l/min flow rate and DN8 and DN20 self-sealing couplings with a 2 m hose (4, 6, 8 or 10 m on request). - **Gases:** up to eight simultaneously; SF6 purity 0-100 % with ±0.5 % (infrared), dew point from −60 to +20 °C with ±2 °C (also in µL/L or ppm), SO2 0-100 or 0-500 ppm, HF 0-10 or 0-20 ppm, H2S 0-100 ppm and CO 0-1,000 ppm with ±2 % FS. - **Mixtures:** SF6 with CF4 (0-80 %, ±1 % of reading, by balance), N2 and air; display mode for SF6/N2 users and gas-cylinder testing mode. - **Automatic cycle:** measurement time of 2, 4, 6 or 8 min, wizard on the 7″ touchscreen, walk-away timer, auto-abort and auto-clean; pre-loaded IEC and CIGRE configurations and custom tests. - **Climate:** three SF6 calibrations, cold (−10 to 9 °C), warm (10 to 29 °C) and hot (30 to 50 °C); operation from −10 to +40 °C (+50 °C without battery charging) and from 600 to 1,100 mbar absolute. - **Data:** 8 GB internal storage (approx. one year), MS Excel-compatible USB export and Unicode printer with an 11-language interface. - **In the field:** wheeled IP66 Peli case, 270 × 560 × 450 mm and 20 kg, a single lithium battery for electronics and compressor (approx. 8 h, 2-4 h charge), optional in-vehicle charging and 2-year manufacturing warranty. ### Advantages **Fully automatic test cycle** Once powered and connected, the analyser draws a small quantity of gas automatically or manually, governed by inlet pressure sensing that accepts up to 35 bar. The vacuum purge cycle and internal storage prevent sample contamination and any SF6 escape during the test. **High-pressure gas return** When the measurement is complete, a 10 bar compressor supplied by the lithium battery returns the gas to the electrical equipment, while several safety functions supervise the cycle. The internal storage bag allows up to five consecutive tests before a pump-back. **Guided operation from the screen** An on-screen wizard on the 7″ (18 cm) touch display leads each step of the test; the walk-away timer and the auto-abort and auto-clean functions reduce operator intervention. Results are printed with the integrated Unicode printer, with the interface available in 11 languages. **Up to eight gases in a single measurement** The instrument accepts mixtures of SF6, CF4, N2 and air, detects toxic contaminants such as SO2, HF, H2S and CO, and reports the water content as dew point, µL/L or ppm. SF6 purity is measured over 0-100 % with ±0.5 % accuracy (IR/density sensor). **Maintenance without return to base** Pre-calibrated sensors are fitted on site through simplified user access, and three climate calibrations compensate drift in cold, warm and hot climates. Built-in moisture traps dry the gas with a desiccant before it is returned; the equipment carries a 2-year manufacturing warranty. ### Applications - Documented SF6 quality control in line with zero-emission obligations. - Maintenance and commissioning of HV circuit breakers, switchgear and transformers in substations. - Testing of SF6 gas cylinders (dedicated mode). ### About the product Current IEC and CIGRE test configurations come pre-programmed, with the option of custom tests; test locations and user names are editable, with password protection, and data is exported in MS Excel-compatible format via USB.

The Rapidox 6100 Pump Back samples automatically, accepts up to 35 bar at the inlet and, after measuring, pumps the dried SF6 back into the compartment with its 10 bar compressor; the Rapidox 6100 Portable, at 8.5 kg and with an inlet up to 10 bar, captures the sampled gas in a recovery bag. **Does it stay accurate in cold or hot climates?** Yes. The Rapidox 6100 Pump Back has three SF6 calibrations, for cold (−10 to 9 °C), warm (10 to 29 °C) and hot (30 to 50 °C) climates, which compensate sensor drift. It operates from −10 to +40 °C, up to +50 °C without battery charging, and reaches full accuracy after a 15 min warm-up at 20 °C. **What does zero emissions mean for this analyser?** The vacuum purge cycle and internal storage prevent any escape during the measurement, and the compressor returns the gas to the equipment afterwards. **How many tests can be run before a pump-back?** Up to five, thanks to the internal storage bag. **Are gas mixtures supported?** Yes: mixtures of SF6, CF4, N2 and air, with inlet pressures of up to 35 bar. **Can a sensor be replaced without returning the unit to base?** Yes. Pre-calibrated sensors are fitted on site through simplified user access. **How are results documented?** On screen, with the integrated Unicode printer, and by MS Excel-compatible export via USB. --- ## Rapidox 7100: multigas analyser URL: https://amperis.com/en/products/switch-testing/sf6/gas-analysers/multigas-analyser-rapidox-7100/ Category: [SF6 gas analysers: purity, moisture, SO2](https://amperis.com/en/products/switch-testing/sf6/gas-analysers/) Series: Gas analysers datasheet: https://amperis.com/en/products/switch-testing/sf6/gas-analysers/multigas-analyser-rapidox-7100/Brochure-Rapidox-7100-MultiGas-EN.pdf > Rapidox 7100: 19-inch rack or benchtop multigas analyser, up to 7 gases, calorific value, 0-10 V, 4-20 mA and Modbus RTU/Ethernet outputs.
