Abstract

Aiming at the defect cases of AC withstand voltage partial discharge detection in GIS handover test, the defect detection process, determination method and treatment measures are described in detail, and put forward effective prevention methods. Tests show that: Due to the AC withstand voltage non-power frequency of the handover test, the characteristics of ultrasonic and UHF PD detection spectra are significantly different from those under operating conditions. A method to determine the defects of discharge source and acoustic signal is proposed, which is of great significance to find out the defects of GIS handover test and is verified by field application.
