Time domain reflectometry (tdr) is a remote sensing technique that uses active backscatter. The technique is applicable to testing for faults and multiple partial faults on cables. The battery-operated hardware developed during this study tailored this technique for testing mining equipment trailing electrical cables. Processing of the backscatter is accomplished using a microprocessor. The visual output from the hardware to the operator is the type, magnitude, and distance to the cable fault in a numerical format.
