Abstract A failure test of electric power cable is composed of signal transmitter and signal receiver. Said signal transmitter consists of a MF power supply (220 V AC), impedance converter for converting 220 V at 800 Hz to 36V AC at 800 Hz, and load regulator for outputting. Said signal receiver is a low-frequency one. Its advantages include simple structure, convenient application, and small size.
