Insulation Resistance Meter AMIC-15k1

Insulation Resistance Meter AMIC-15k1

Features

  • The partial discharge indicator PDI.
  • Diagnosis of insulation systems based on standard measurements of IR, DAR, PI, SV, RT, DD
  • Allows to test the electrical durability of the tested object - indication of breaking voltage.
  • The high resistance to electromagnetic interference ensures uninterrupted operation in power plants and near high-voltage transmission lines up to 1200 kV AC and 500 kV DC.
  • The smooth voltage rise over time function (RT - Ramp Test) allows partial discharges to be indicated in the installation and their partial location to be determined.
  • An efficient inverter with a power of approx. 150 W will intensify the potential damage point to facilitate the location of the fault using the following methods:
  • Visual method (if cables are visible along their entire length)
  • Reflective methods, seismic-acoustic wave detector, or with sampling to indicate the direction of the fault (the conductor must be buried in the ground with direct contact to earth).
  • Compatible with external software.

Applications

The AMIC-15k1 meter is designed to measure the insulation resistance of electrical energy objects, i.e:

  • Single and multi-core cables,
  • Transformers,
  • Engines and generators,
  • Capacitors, switches and other devices installed in power stations.

It is especially recommended for measurements in areas with very high electromagnetic disturbances, e.g. electrical substations with 1200 kV AC and 500 kV DC. Thanks to the measuring voltage of 15 kV (according to ANSI /NETA ATS-2009 TABLES 100.1) the meter can be used to measure objects with a nominal voltage exceeding 34.5 kV.

Features of the equipment

Highly efficient HV inverter with test voltage of 15 kV and current up to 10 mA, ideal for measuring insulation resistance up to 40 TΩ. Achieving this result makes this equipment unrivalled. The three-wire resistance measurement, performed with the "GUARD" cable, eliminates the surface leakage current caused by contaminated insulation, which increases the reliability of the results obtained.

The equipment indicates the absorption coefficient (DAR - dielectric absorption ratio), the polarization index PI and the dielectric discharge value (DD).

The device allows the user to evaluate the state of the insulation by applying test voltage either incrementally in steps (SV) or slowly on voltage ramps.

  • In the stepwise method (SV) the solution guarantees that a dielectric in good condition will provide the same results, regardless of the voltage applied.
  • The Ramp Test Method (RT) allows us to determine the insulation characteristics of the material. The meter gently increases the measuring voltage without exposing the object to so-called electrical stress. It records the time and the value of the voltage at which the electrical breakdown of the insulation occurred.

Built-in digital filters, with an average time of 10, 30, 60, 100, 200 sec guarantees stable measurement results in areas of strong electromagnetic interference.

Burnout

A very useful solution is the function that allows the exhaustion of the damaged object. In the case of exposed cables, it allows visual identification of the fault location. In the case of shielded cables, the method allows for the generation of a seismic sound wave from the location of the damage.

Under special conditions, an energy discharge will appear cyclically. By using the geophone it will be possible to pinpoint the exact location of such a discharge.

The exhaustion function also allows to locate transient faults (which appear, for example, only during rain) with the support of reflectometry, and in case of a short circuit (of a protection or return cable) to earth - applying the voltage drop measurement method (Figure A).

Automatic saving of measurement results

The device automatically saves the measurement results. The number of "auto-saved" points depends on the amount of data, which is saved within the main memory.

Data analysis

The Amperis AMIC Mobile application allows you to observe the results during the measurement. The application can generate real-time graphs in various configurations. This allows you to evaluate the state of the object during the tests.

The option of remote start and stop of the measurement is particularly useful. Thanks to this, tests can be performed remotely, e.g. from another room or inside the car, when there are difficult weather conditions for the user. Using the phone's GPS, which allows the measurement location to be determined. Thanks to the mobile application and the Amperis Reader software, the user can store data from previous measurements and compare them with the current results transferred from the meter's extensive memory.

This solution makes it possible to prepare a measurement report, monitor the progress of insulation degradation and thus plan renovation work.
