1.Partial discharge detector Overview

Portable Partial discharge detector 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.
