ABSTRACT:
An electric leakage detection system having: a detection point forming circuit which forms a detection point being connected through three resistors which are star-connected to a three-phase output line of an AC generator; a voltage detection circuit which detects a voltage across the detection point and ground; and an electric leakage detecting part which detects existence of an electric leakage from a period of the detected voltage and determines an occurrence position of the electric leakage from a period of the detected voltage.
