750kV电压互感器准确度现场校验方法

Verification method of the accuracy of 750 kV voltage transformer in locale

利用高压标准电容及高压介损电桥,并使用间接比较法进行现场750 kV电压互感器误差校验,解决了传统750 kV标准电压互感器不便于运输及现场吊装的难题。

Combining with the locale situation,using high voltage standard electric capacity and high voltage dielectric loss bridge,and using indirect comparison method make locale error verification of 750 kV voltage transformer.Solves the hard problems of transportation and locale hoisting for the traditional 750 kV standard voltage transformer,provides the convenience for checking,accepting and testing the equipment of 750 kV substation.
