| Abstract: | Starting from the essence of grounding, the author analyses that the short circuit current is the controlling factor of grounding resistance. The author analyses factors of soil resistivity to the ground resistance： soil moisture, soil temperature, soil structure types. The author puts forward measures of reducing ground resistance of substation in the high soil resistivity area and some of the ways of grounding grid design. |
