| Abstract: | This paper mainly introduces the causes of grounding fault in substation DC system, the influence on equipment, the advantages and disadvantages of traditional DC grounding fault finding method and new DC grounding fault finding method. The traditional method has the problems of long search time, easy loss of load and low accuracy. By adopting a new type of DC grounding fault locator, it can effectively eliminate the fault and ensure the safe and reliable operation of the DC system in the substation. |
