Research on Partial Discharge Detection methods for Electrical Equipment Diagnosis

Switchgear charged for fault detection, principles and methods the live test from switchgear partial discharge, analyzes the use of ultrasonic detection assays and transient voltage for the switchgear cabinet feasibility of fault diagnosis; using a combination of switchgear partial discharge founding live testing equipment failure cases, by power testing experimental analysis confirmed the presence of switchgear failure to verify the validity of partial discharge detection in live test switchgear fault diagnosis.
