Analysis of 500kV Capacitive Voltage Transformer Leakage Fault

Abstract

Capacitive voltage transformers are increasingly used in power grids. Abnormal failures and other situations have also increased. In-depth analysis of the failure mechanism of CVT is conducive to improving the monitoring technology and means, intervening in advance to reduce the occurrence of serious accidents. This article focuses on the analysis of the cause of the oil leakage failure CVT and the disassembly inspection of the return to the factory to find out the cause of the failure and provide theoretical support for the subsequent avoidance of the same type of failure.
