Abstract For obtaining a better electromagnetic (EM) environment around the transmission or distribution line, it is necessary to detect and locate source of radiated EM interference as soon as possible. When locating source from electric power equipment, because of the possible existence of multipath wave on the propagation path, the signals received by antennas become complicated and the location accuracy may deteriorate. In this study, the TDOA (time difference of arrival) methods for source localization are widely investigated, and the applicable methods to radiated EM interfering waves are summarized. Secondly, the applicability and the estimation accuracy of the applicable methods in a multipath environment are discussed by the numerical simulations.

Key words： Discharge fault source localization time difference of arrival methods multipath propagation environment numerical simulation
