(a) A zero-sequence current transformer that detects the zero-sequence current flowing in the main circuit. (b) An abnormal voltage protection unit connected to the zero-sequence current transformer, which converts the zero-sequence current into a signal and outputs an abnormal voltage. (c) An amplifier circuit that amplifies the abnormal voltage from this abnormal voltage protection section. (d) A sensitivity setting circuit connected to this amplifier circuit and setting the sensitivity for determining the abnormal voltage as a ground fault. (E) A regulator that is connected in parallel to this sensitivity setting circuit and continuously adjusts the sensitivity. (f) A relay control circuit that is connected to the output side of the sensitivity setting circuit and excites the control relay. (g) A tripping winding activated by excitation of the control relay. (H) A switch that is connected in series to this tripping winding and locks the operation of the interrupter.
