| Abstract: | Based on the analysis of the single-phase ground fault type in the distribution network,a new method that can distinguish the fault phase by the variation of the voltage is presented.The fault degree criterion and the judgment formula are put forward.They can be expediently applied to the judgment of ground-fault type and its degree. |
