On the Use of Electromagnetic Time Reversal to Locate Faults in Series-Compensated Transmission Lines

The paper focuses on the extension to series-compensated multiconductor transmission lines of a new fault location method based on the Electromagnetic Time Reversal (EMTR) theory. The applicability of the EMTR theory to locate faults is first summarized. Then, the paper describes the proposed algorithm to locate faults in multiconductor transmission lines using a single observation point at one of the line terminals. The application of the proposed method to series-compensated transmission lines is finally illustrated by numerical simulations obtained using the EMTP-RV simulation environment where electromagnetic fault-transients are reproduced with reference to a realistic series-compensated overhead transmission line. The resulting fault location accuracy is quantified and analyzed with reference to different fault types.
