500kV电容式电压互感器不拆高压引线预试方法探讨

Discussions on Preventive Test of 500 kV Capacitive Voltage Transformer without Disconnecting High Tension Leads

对５００ ｋＶ变电所２ 种安装形式的电容式电压互感器 （以下简称ＣＶＴ） 不拆线预试进行了分析， 特别对线路侧ＣＶＴ不拆线对测试的影响作了探讨。

This paper analyzes the preventive test of two installations of capacitive voltage transformers (CVT) in 500 kV substation.It also analyzes the impact to the test results without disconnecting the high tension leads,especially for the CVT installed on the line side.
