故点標定装置。[Scope of Claim for Utility Model Registration] A gas pressure sensor for detecting gas pressure provided in each gas compartment of a gas insulated switchgear in which a container housing each element is divided into a plurality of gas compartments; an amplifier circuit that amplifies the difference between the detected value of the gas pressure sensor and the bias voltage at a constant amplification factor; and bias voltage setting means that reads the detected value of the gas pressure sensor at a constant cycle and provides the value as the bias voltage of the amplifier circuit. Gas pressure change detection means for determining the amount of change in the output value of the amplifier circuit, and fault point determination means for determining the gas section where the ground fault has occurred by comparing this amount of change with a predetermined judgment value. An accident point locating device for gas insulated switchgear, characterized by:
