A NEW TRAVELING-WAVE BASED SCHEME FOR FAULT-DETECTION ON OVERHEAD POWER DISTRIBUTION FEEDERS

This paper presents the results of investigations into a new fault location technique for overhead power distribution systems. The scheme is based upon detecting fault-induced high frequency components on distribution lines. This should enable the detection of discharges from the low-level breakdown of insulators, which can not be detected by conventional methods. The location of a fault is determined by appropriate signal processing of the fault generated signals on the line. Simulation results are used to illustrate the basic features of the performance of the new scheme on a simple radial 11kV feeder system.
