- © 2019 IEEE.This paper introduces a novel approach to detect and locate faults in AC transmission lines. The fault location process is carried out using wavelet correlation modes and taking into account the short-circuit theory. To validate the new proposal, several tests were conducted in ATP-EMTP software considering a wide variety of simulations. Additionally, the fault location is done using a new mother wavelet, called wavelet ET that was previously obtained considering the transient information produced by switching transients and faults. The obtained results shows satisfactory during the fault location process which is analyzed in a multi-terminal transmission line. The mean error achieved was lower than 1 % for solid-grounded faults.
