Noncontact Probes for Wire FaultLocation With Reflectometry

This paper describes an approach to locate wire faults using reflectometry without physical contact with the wire conductor. This noncontact method is capable of locating faults on both dead and live powered wires with today's reflectometry technologies, and it does not require any modification or disconnection of the existing wiring system. With proper configuration, this method can detect wire faults with an accuracy of 3 in, which is comparable to direct connection systems
