Fault Feeder Identification in Non-effectively Grounded Distribution Network with Secondary Earth Fault

Journal of Modern Power Systems and Clean Energy, 2021
Secondary earth faults occur frequently in power distribution networks under harsh weather conditions. Owing to its characteristics, a secondary earth fault is typically hidden within the transient of the first fault.
