Abstract

Electromagnetic time reversal (EMTR) has emerged as a promising fault location technique in terms of location accuracy, robustness against uncertainties on fault impedance and reduction of measurement points. In this paper, we present a full-scale experimental test on an unenergized 677-m long, double-circuit 10-kV distribution line of an EMTR-based fault location method previously proposed by the authors. The fault is emulated by injecting a pulse into one of the phases of the power line. The transients generated by the emulated fault were measured at one end of the line. The measured signals were time-reversed and back-injected into a model of the power line in order to quantify the EMTR-based fault location performances. To the best of the authors’ knowledge, this is the first experimental validation of the EMTR-based fault location technique in a real full-scale power line environment.
