Research of Fault-Indicator Based on Transient Features for Neutral Indirect Ground System
摘要
Abstract
On account of the weak fault current,unstable fault arc and the weak capacity of fault-indicators,the loca-tion of singled phase to ground fault in neutral indirect ground system haven't been thoroughly resolved.With studying the single-phase fault transient features,a new high precision fault-indicator is introduced and designed that realized distributed single-phase fault location using intelligent distributed feeder automatic algorithm.With building RTDS environment and installing devices in actual scene,the results illustrate that the new fault-indicator has high precision sampling,high accuracy fault judgment,and gets correct single-phase fault location including different initial fault angle,different transition resistance,different fault position.关键词
