摘　　要：针对５００ｋＶ ＣＶＴ运行事故，通过ＣＶＴ 不同放电类型及其实验数据的分析。This paper discusses the influence and possibility of partial discharge on CVT according to the faults of 500kV CVT in Northeast Power System of China. With the simulating tests, a method based on partial discharge(PD) on line monitoring is presented to predict faults of insulation.
