The current problems of substation grounding have become increasingly prominent, commonly used resistance reducing measures limited by various factors, and other issues, the use of natural grounding body in reducing substation grounding resistance is discussed, and combined with a Fujian 110 kV substation reconstruction case, the rationality and superiority of natural grounding device are analyzed. It is believed that in the grounding project, full use of natural grounding body can not only reduce grounding resistance, but also save time and materials, stable grounding resistance, extend using...
