The paper presents a method to locate flashovers resulting from direct lightning strikes to overhead transmission lines. The method exploits the electromagnetic time-reversal theory and uses the cross-correlation between the flashover-originated transient current observed in the direct time and the transverse branch currents in the reversed time at the guessed flashover locations as a similarity metric to identify the location of the flashover. The performance of the similarity metric is numerically illustrated using two simulation case studies associated with a shielding failure and a back-flashover.

Abstract

The paper presents a method to locate flashovers resulting from direct lightning strikes to overhead transmission lines. The method exploits the electromagnetic time-reversal theory and uses the cross-correlation between the flashover-originated transient current observed in the direct time and the transverse branch currents in the reversed time at the guessed flashover locations as a similarity metric to identify the location of the flashover. The performance of the similarity metric is numerically illustrated using two simulation case studies associated with a shielding failure and a back-flashover.
