Analysis of Single-phase Ground Fault in Small Current Grounding System
Xueqiang Chen · Energy and Energy Conservation · 2011
In this paper analyzed the single-phase metallic ground fault in neutral point grounding system,and analyzed the transition resistance ground fault in different circumstances occurring,find a regular pattern of three-phase voltage when resistance transition Single phase earthing,point out science-based for distinguish fault identification,correct the error happened in operation,scheduling personnel determining the ground phase,it is important for handling on-site operation and incident.
