Discharge intensity Download Corona Corona is a type of partial discharge in which electrons are emitted into the air. The mechanism of electron emission belongs to the realm of physics. The whole process begins when cosmic rays ionize the molecules in the air surrounding the high-voltage equipment by deflecting an electron from its orbit. View the effect of ionization The free electron released in the process is repelled by the electric field surrounding the hardware during its negative phase. And attracted during the positive phase. If the repulsive force pushes the electron to a sufficiently high velocity, then it will cause more than one electron to be released during a collision with another air molecule. When two or more electrons are released by collision, an avalanche is formed. The avalanche will continue until the electric field has decreased in strength to the point where it does not accelerate the electron to a velocity fast enough to release an electron during a collision. In this phase, the collision causes the excitation of the molecule. The molecule wants to return to its neutral state. To do so, it emits the excess energy in the form of photons of light. The frequency of the photons is the same as that of the photons. The frequency of the photons depends on the atoms and the bond types of the excited molecule. In the case of N2 (the main component of the air around us), the frequencies of light emitted are mainly in the UV range, with only 5% above 400 nm, which is considered the lower end of visible blue.\n","permalink":"https://amperis.com/en/products/cameras/corona-effect-cameras/","title":"Corona Effect Cameras"},{"content":"Handheld SF6 leak detector and portable monitor in one unit\nThe D-TEK narrows down the leaking area in cloud-hunting mode with ppm indication and then pinpoints the exact spot — two instruments in a single handheld unit with a field-replaceable infrared sensor.\nAdvantages Two detectors in one\nThe cloud-hunting mode works like a portable monitor, showing ppm concentration on the large LCD to locate the leaking area fast; the pinpoint mode then isolates the exact source.\n","permalink":"https://amperis.com/en/products/switch-testing/sf6/sf6-leak-detectors/d-tek-sf6-leak-detector/","title":"D-TEK: SF6 leak detector"},{"content":"Dielectric test sets for insulating protective equipment verify the electrical safety of the gloves, sleeves, blankets, mats, hot sticks and rods that protect live-working personnel.

Employing SF6 gas in switchgears is found to be a more effective method than relying on air or vacuum for dielectric functions. SF6 gas not only provides insulation, it provides the kind of stable operation at routine pressure levels that vacuum cannot provide.\nThat being said, SF6 gas has a high degree of greenhouse effect associated with it. Hence, simply releasing this gas into atmosphere is not only utterly unprofessional but also very dangerous for our planet. That’s where the SF6 gas recovery units from the AGRU-8 series come in. These units are extremely effective in utilising the negative pressure (partially or wholly) provided by gas absence in switchgears to extract and store traces of SF6 gas in the provided storage tanks. Thus, you can ensure that you maintain an efficient and environment-friendly operation while saving SF6 gas for future usage after purification.\nThe operation of AGRU-8 series units is very simple and convenient. The operation consists of a simple 2-valve system that can be used to recover up to 99.99% of SF6 gas in one cycle.\nThe operation schematic is given below: ","permalink":"https://amperis.com/en/resources/articles/sf6-gas-recovery-unit/","title":"SF6 gas recovery unit"},{"content":"The measurement of a solution’s ability to conduct electricity is called conductance.

A load bank is an instrument which forms an electrical load, formulates that load to an electrical power system, converts it and delivers the required end output to that system. Used to test the power sources like generators and batteries, it actively performs its role of a power protection system. Moreover, it is a standard practice to use load banks in laboratories, industrial testing facilities and telecommunication facilities for the maintenance of batteries. Load resistor bank This is the most common type of a load bank. When the electrical energy has to be deformed into heat, power resistors fetch the heat from the load bank by either air or water or by any forced means or convection. This creates a load which is suitable for this type of load bank.\nA load resistor bank is a powerful energy equipment which generates loading equivalent to, say generators and prime mover.

Amperis has a wide range of equipment related to the maintenance of transformers.\nThe power factor will always be the ratio between the losses (milliwatts) and the load (millivoltamperes); and the value obtained will depend only on the humidity and the temperature of the equipment under the conditions in which it is operating (regardless of the thickness or the area of ​​the insulation). Since the temperature of the unit under test, the results vary, the readings must be corrected to a reference Tº of 20ºc, that is why this is an alternating current test. The criteria to be followed to consider an acceptable value of power factor are the following: 0.5% of a new transformer up to 2.0% for a transformer contaminated or degraded in its insulation, always referred to 20ºc. If the value is higher than 2%, an investigation of the cause of the weak insulation is required (for example, penetration of water into the insulating oil).\n","permalink":"https://amperis.com/en/resources/articles/test-power-transformers/","title":"Test on power transformers"},{"content":"In every electrical device there is a complete circuit or we can say a series of inputs which contribute to the final output.

A large client base, spread all over the globe, can vouch for our high standards of quality, reliability and safety when it comes to supplying various high voltage test equipments. More about Portable VLF Testing Series AXV:\nVLF range is defined as a frequency range at or below 0.1 Hz for typical sinusoidal waves. This frequency range is extremely useful for testing various equipments, without actually causing any damage to the equipments being tested. In addition, it is a viable alternative to conventional high-power consuming DC Hipot tests. In this indirect non-destructive technique, AXV series models apply a preset sinusoidal voltage to the equipment or component being tested. This voltage reaches the peak at 25% completion of the cycle, after which the voltage goes down until it reaches the zero (ground) level. The same process is repeated in the reversed polarity for the next half of the cycle. All of the equipments in our AXV series of VLF testing methods are equipped with cutting-edge microprocessors and computing systems. These microprocessors make sure that the voltage charged and discharged for testing through the equipment remains very precisely monitored. Also, the output sensors and display devices are integrated into the microprocessor logic to make it a compact, precise, efficient and reliable set up.

To do this, sensors or transducers are used to convert the variations of the physical phenomenon into proportional variations of an electrical variable. The most commonly used electrical variables are: voltage, current, load, resistance or capacitance. However, this variety of electrical signal types must be processed to be understood by the digital computer. In addition, it provides electrical isolation and signal filtering in order to protect the system from noise originating in the field.\n","permalink":"https://amperis.com/en/recursos/glosario/s/scada/","title":"SCADA"},{"content":"Multidrop transmission bus system, ideal for transmitting at high speeds over long distances and through noisy channels, since it reduces the noise that appears in the voltages produced in the transmission line.\n","permalink":"https://amperis.com/en/recursos/glosario/r/rs-485/","title":"RS-485"},{"content":"Interface for the serial exchange of binary data between a data terminal equipment and a data communication equipment), for example, there are occasions when it is of interest to connect other types of equipment, such as computers.\n","permalink":"https://amperis.com/en/recursos/glosario/r/rs-232/","title":"RS-232"},{"content":"The polarization index (PI) is defined as the ratio between the insulation resistance measured 1 minute and 10 minutes after applying the DC test voltage.
