Shuai Zheng · Relay · 2006
Single-phase grounded line detection is a difficult problem existing for a long time.This paper analyzes the characteristic and problems of single-phase grounded line detection in arc suppression coil grounded system when single-phase grounded.A scheme of arc suppression coil grounded system with medium resistance is put forward.It's proved that the safety of power system is not influenced,and the grounded line can be detected quickly and accurately.
