Fault Line Selection Method Considering Grounding Fault Angle for Distribution Network

Journal of Northeast Agricultural University (English Edition), 2015
Abstract In the distribution network system with its neutral point grounding via arc suppression coil, when single-phase grounding fault occurred near zero-crossing point of the phase voltage, the inaccuracy of the line selection always existed in existing methods.

Fault Line Selection with Parallel Supply Lines in Mine Power Systems

Advanced Materials Research, 2012
In mine power systems, false operation and failure operation of relays in parallel supply lines often take place when single phase grounding fault occurs. A novel method based on phase-to-phase current difference is proposed as line selection criterion in this paper.
