摘要
Abstract
A single-phase ground fault of 1 000 kV busbar GIS in an UHV AC substation occurred due to in-sulation. The fault point is hard to detect. The paper comprehensively analyzes protection action of busbar in case of the fault by protection action report and fault recording; By means of distribution magnitude of short-circuit current and its direction during the fault occurred, it suggests the detection area, narrowing the area of fault detection and providing strong technical support to fast detection of fault point.关键词
