Patent number: 9158023Abstract: A method and an apparatus provide targeted guidance for a user to locate and trace-out the path of a buried electrical cable, and to locate a cable fault along the cable. A current pulse is applied to the cable, whereby a magnetic field is generated around the cable and an acoustic signal is emitted from the cable fault. The apparatus detects and measures magnetic field information to locate the cable. The apparatus measures a time delay between detecting the magnetic signal and detecting the acoustic signal. By comparing successive time delays at successive measuring positions, a relative proximity to the cable fault is determined.
