Abstract

This paper presents a method to locate lightning-originated flashovers in overhead transmission lines. The proposed method is based on the electromagnetic time-reversal theory and uses the voltage transient signals initiated by the flashover to identify its location. The method relies on the use of a single observation (measurement) point located at the primary substation and can be applied to different power network topologies. The performance of the proposed method is validated by using several numerical simulation case studies and by analyzing the impact of the surge arresters on the location accuracy of the flashover.flashovers in overhead transmission lines.
