| Abstract: | According to the theory of networks,this paper presents a new method of fault diagnosis for the grounding grids.The criterion of fault diagnosis of using accessible voltage is proved on the paper.The method of interval fault location of grounding grids is found by the concept of tearing networks.The result of simulating shows this method of fault diagnosis is effective and applying to engineering. |
