摘要

针对带负荷下进行线路的电流互感器极性校验工作的难度和危险性提出一次升流试验方法对线路TA进行极性和差动校验的新方式

并在某条新建线路的调试中检验其可行性。同时讨论在进行线路一次升流中应该注意的事项

提出解决办法。

Abstract

A new method of checking polarity and differential protection trough rising current of primary equipment is presented according to difficulty and danger of checking CT polarity with load.And its’ feasibility was confirmed in the debugging of a new-built transmission line.Matters need attention and operable solutions are discussed during rising current of primary equipmentt.
