| Abstract: | Grounding resistance must satisfy the demand of contact potential difference and step potential difference in the design of grounding grid.Grounding grid is commonly horizontal and composite.All kinds of resistance reduction methods are compared technically and economically according to circumstances of geology and geomorphology.Characteristics of general used resistance reduction methods and their problems are described.The scientific reasonable method is chose to satisfy the demand of contact potential difference and step potential difference and to achieve the purpose of resistance reduction. |
