要約(英語): In recent years, the response to a ground fault in a power facility has consisted of insulating the electrical circuit using the ground relay. However, this method does not determine the cause of the ground fault. In this study, focusing on three major causes of a ground fault, “tree contact”, “wildlife contact”, and “insulator deterioration”, we determine the cause by using a new decision method. The decision method proposed in this study can determine the ground-fault cause with high accuracy by using the characteristic of the ground-fault current waveform shape of each ground-fault cause, and thus, it is possible to construct a sophisticated energy supply and demand system.
