China Transformer Pd Monitoring Digital Partial Discharge Detection and Analysis System, Find details about China Partial Discharge Tester, Partial Discharge Testing from Transformer Pd Monitoring Digital Partial Discharge Detection and Analysis System
I.Portable partial discharger inspector Overview:
Portable partial discharge inspector is mainly used for live detection of high voltage electrical equipment. This product is simple to operate and adopts portable structure design which can inspect on line. It equips with specific sensors to detect various high-pressure devices, which can detect the insulation state changes inside the equipment timely. So the insulation failure could be dealt with in time.
