Existing travelling-wave fault-location methods are known to perform poorly on branched networks. In this paper, a new fault-location method for use on highly branched networks is demonstrated. The method is based on the retrieval of global positioning system time-stamped arrival times of the fault-induced high-frequency transient. It is shown that for an unambiguous estimation of the fault location, a time-stamp is required from a fault recorder located in each of the two directions from the fault position; therefore, complete coverage of a network can be achieved with a fault recorder on each branch termination. The system is also capable of locating the origin of incipient faults and, therefore, provides a means of detecting potential future faults so remedial action can be taken.
