文摘

Single line-to-earth fault may become double line-to-earth faults. In this case, the procedure for determining the fault location takes a long time, as a team of experts conducts bypassing the entire network. A method for fault location of double line-to-earth faults on different power lines of medium-voltage distribution network is proposed in the article. The method is implemented by determining the impedance of the line-to-earth fault circuit which is proportional to the distances to each of the places of faults. The results of theoretical calculations coincide with results of simulation performed in MatLab Simulink software environment.
