Study of Insulation Fault Phase Location Method for Unearthed IT System Considering the Influence of Distributed Capacitance
摘要
Abstract
This paper analyzed the system voltage variation vs grounding resistance before and after grounding fault was conducted,considering the influence of distributed capacitance.Four characteristics quantities which indicate the fault phase were found.Furthermore,a fault phase locating method based on these characteristics was proposed.And also,judging threshold turning method and fault phase locating flowchart were provided.Finally,experiments were conducted in a prototype system,and the results show that the locating method is effective.关键词
