Abstract

PURPOSE: To prevent the effects of disconnection trouble on the other consumers at the time of an earthing trouble under the condition that overcurrent raly is energized by starting current, etc., by adding relay and diode element to the conventional circuit.
CONSTITUTION: When an earthing trouble occurs in high voltage power consumer house under the condition that a SOG type load switch-built in overcurrent relay is operated by starting current, etc., to energize the relay 407, the power source of the earthing realy 9 is not restored before the relay 407 is reset, and thus the time to remove earthing trouble in the house is put off, causing the earth directional relay of power firm to operate, which results in the influence of the trouble to the other consumers. To counter this trouble, the relay 419 besides the relay 407 is newly set and also the diode 418 for preventing the flow of energy stored in the condenser 408 provided in order to reset the relay 407 in a limiting time into the relay 419 is additionally set. Thus, the power source of the earthing relay 9 is controlled by the contact 420 of the relay 419.
