Abstract:
     This invention relates to a method for testing discharge faulty positions for high voltage electric devices including utilizing a directional antenna to receive the magnetic wave signals radiated by the discharge part space, utilizing a directional piezoelectric wafer to receive the supersonic wave signals of the part, analyzing the amplitudes of electric and sonic signals and change of time differences by a data process circuit to determine the coordinates of X, Y and Z shafts so as to determine the position of the discharge. The invented detector is composed of a directional antenna, a piezoelectric wafer, an electric signal receiving circuit, a data process circuit and a display device.
