Arc grounding fault is very common in distribution network

which is not easy to be found and has great harm. Its mechanism is complex and random. In view of the above problems

we elaborated the causes and hazards of arc grounding faults in distribution network

mathematical models of arc grounding fault

suppression strategy of arc grounding fault

identification

location and protection of arc grounding faults

and physical simulation experiments and simulation tests of arc grounding fault. Moreover

we summarized and analyzed the research status at home and abroad

and prospected the research direction of arc grounding faults in distribution networks. The research framework of arc grounding faults in distribution networks is proposed from following four aspects: fault model research and digital simulation software development

suppression strategy research and device development

fault identification and protection strategy

and physical simulation and digital analog hybrid simulation test technology.
