摘要
通过对选择性漏电保护与两零序电流互感器的零序电流方向的漏电保护分析,说明两零电流互感器漏电保护更易判断保护范围内的漏电故障。
Through drain protection principle for choosing drain protection and residual current direction protection by using two residual current mutual-inductor,proves that it is easier to determine drain faults by using the latter in protection range.
