In this work a new single-ended method for fault location in distribution networks is proposed. The method is an active traveling wave fault location, which transmits a Gaussian chirp through the line and applies the cross time-frequency reflectometry in order to find the exact location of the fault with 150 meter tolerance. The method functions in the offline post fault condition, where the system is disconnected. The bandwidth of the proposed method is at least one order of magnitude smaller… CONTINUE READING
