Single and double ended travelling-wave fault location on a MV system

Single and double ended fault location for MV distribution systems, based on the traveling waves theory, is presented. The proposed scheme operates on the incident transient currents traveling from the fault point and measured at either one or two substations on the transmission line. In spite of the complexity introduced by the many discontinuities created by the sub-feeders in the system, the results of several observed faults on a 23.8 kV system demonstrate the viability of traveling wave technique for distribution systems.
