  • Page 9: Non-Intrusive Detection Of Partial Discharge Activity

    EA Technology UltraTEV Plus Operating Manual 2388L015 Non-Intrusive Detection of Partial Discharge Activity What is Partial Discharge? Partial discharges are electrical discharges that do not completely bridge the insulation between electrodes. The magnitude of these discharges is usually small, however they cause progressive deterioration of insulation that may eventually lead to failure.

  • Page 10: Electromagnetic Discharge Activity

    EA Technology UltraTEV Plus Operating Manual 2388L015 The most sensitive method of detection is using an airborne ultrasonic Microphone centred at 40 kHz. This method is very successful at detecting partial discharge activity provided there is an air passage between the source and the Microphone.
