摘要
通过对某220kV出线C相接地短路造成新原理差动误动原因的分析，澄清了新老原理在判据上的混乱，提出了故障分量纵差保护的正确整定方法。
The cognition of longitudinal differential protection based on fault componentis very divergent among the developers of main equipment protection,these divergenciesare concentrated in refference[1. 3]. Compare it with traditional type protection,which ismore sensitive and more selective, it is a very critical question. In order to develop mainequipment protection healthily,it is necessary to discuss on it and to make it clear.
