  • Devices, methods, and systems for localizing a fault on a live cable
    Patent number: 9863997
    Abstract: Devices, methods, and systems for localizing a fault on a live cable are described herein. One system includes a wire fault localizer configured to receive current information from a location where direct current is applied to a cable comprising a number of loads, receive additional current information from at least two additional locations on the cable, wherein one of the at least two additional locations is on a source side of the cable and one of the at least two additional locations is on a load side of the cable, determine a fault resistance of the cable based on the received current information and received additional current information, and determine a fault distance on the cable based on the fault resistance.

  • Methods for detecting a hidden peak in wire fault location applications—improving the distance range resolution
    Patent number: 8324906
    Abstract: Hidden or overlapped peaks may occur when using SSTDR technology to determine ware faults. These hidden/overlapped peaks may cause false negative determinations (no fault) when testing a wire for faults. In one method of the present invention, the symmetrical property of the SSTDR wave envelope is used to resolve hidden/overlapped peaks. In another method of the present invention, the calibrated normalized loop back SSTDR wave envelope may be used to resolve hidden/overlapped peaks.
