要約(英語): It is expected by applying switch with built-in sensor to distribution line that effective operation and voltage control method in distribution line improve to solve the voltage problem by reverse power flow from renewable energy resources. There is a possibility of the estimation of ground faults location from current and voltage of wave form in ground faults using switch with built-in sensor information. The study to estimate ground faults location is performed continuously, but this technology has not been implemented because sufficient observation information related to aspect of ground faults location and test condition cannot be obtained. The authors report that distribution line simulator changing length of distribution line in the laboratory is constructed in consideration of neutral point connecting method at high resistivity and effect from other distribution line in same substation and that validity is evaluated by voltage value in sound-phase and ground faults current of wave form.
