GIS Partial Discharge Detection

Ultra High Frequency Partial Discharge Detection:The ultra high frequency signals generated by partial discharges in power equipment can only leak out through non-continuous metal parts. Place the ultra high frequency sensor on insulators without metal flanges, or on insulators with partial discharge detection ports, observation windows, or insulation lead-out parts of grounding switches. Detect electromagnetic wave signals in the ultra high frequency band (300MHz～3000MHz), determine whether there is a partial discharge inside the device, and identify the type of defect through the waveform spectrum.

Ultrasonic Partial Discharge Detection:Place the ultrasonic sensor in close contact with the device casing (or use a coupling agent) to detect whether there is a partial discharge inside the device. At the same time, determine the type of defect through the waveform spectrum and locate the position of the discharge point.
