摘要
本文研究了电力系统中由于接线变更导致零序方向保护误动作的现象，提出了利用负荷电流和工作电压的检验方法，并探讨了该方法在其他保护装置中的应用。
In this paper, the phenomena that the wrong operation in zero-sequence direction protection is caused by wining change in power system is investigated, and a new examination method is pat forward to avoid the phenomena by taking advantage of load current and work voltage, in addition, it discusses the application of this method in other protective equipment.
