摘要
介绍了两相电流式负序电流继电器的负序电流滤过器及其构成原理，对两相电流式负序电流过滤器的常用试验方法所产生的误差进行了分析，提出了两种新的试验方法。
Negative current filters constitution principle for two-phase current transformers types negative sequence current relay was introduced.We have made analysis of the error produced by general testing method on two-phase current negative sequence filter and presented two kinds of new testing method for reference.
