摘要
在配电自动化系统运行过程中,极有可能出现小电流接地故障。文章主要是围绕小电流接地故障三态定位技术展开讨论,首先分析了小电流接地故障暂态分布特征,介绍暂态定位存在的问题,提出具体的状态定位方法和实现方式,以期能够为相关人员提供参考。
During the operation of the distribution automation system,it is highly probable that a small current ground fault will occur.This research mainly focuses on the tri-state positioning technology of small current grounding faults.Firstly,it analyzes the transient distribution characteristics of small current grounding faults,introduces the problems of transient positioning,and proposes specific state positioning methods and implementation methods.Relevant personnel have a reference value.
