对变压器零序保护实现方式的探讨

Discussion on implementation of zero-sequence protection for transformer

对 110kV以上电压等级变电站的变压器零序保护的常规实现方式提出了异议 ,分析了它的存在问题 ,探讨了改进后的实现方式。

Some problems to the traditional implementations of zero-sequence protection for transformer in substation at above 110kV voltage grades are pointed out in this paper. The improved implementations are discussed as well.
