摘　　要：小电流接地系统是我国35kV及以下电网最常用的接线方式,而其单相接地故障又是最常发生的。本文对现有各种故障定位原理和技术进行了归纳,分类讨论了各种方案的原理,并提出了尚待解决的问题。Small current neutral grounding system is the most-commonly used wiring mode in 35 kV and below power network, while single phase fault is mostly occurred. Different fault location principle and technology are summed up, the principles of different schemes are classified and discussed. The problems to be solved are put forward.

关 键 词：小电流接地系统 故障选线 故障区段定位
