| Abstract: | The neutral grounding via low resistance is widely used with advantage of rapid removal of faults and low voltage level. Through the single-phase ground fault simulation test of substation outlet, the key problems of step voltage and instantaneous overvaltage in single phase ground fault of the low resistance neutral groundings system are researched in this paper. |
