互感器变比现场校验方法的探讨

Probe Into the Way of Site Proof Test of Transformation Ratio of Transformer

介绍一种新的互感器变比误差现场试验方法——对比测试法 。

This paper introduces a new way to test the transformation error of transformer on site contrast test method, which settle the contradiction between the increasing precision of transformation ratio and the not so accurate site instrument
