Partial Discharge Testing Equipment
AR700
-
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.

Electrostatic Discharge Test
-
The electrostatic discharge test is designed to determine the ability of equipment to perform its intended function without permanent degradation of performance as a result of an air discharged electrostatic pulse. Electrostatic discharge is the result of an unbalanced electrical charge. Typically, it is created by insulator surfaces rubbing together or pulling apart. A transfer of electrostatic charge between bodies (materials, components, etc.) at different electrostatic potentials is caused by direct contact.
