Based on Small Current Grounding Fault Analysis and Testing

Abstract:

distribution network line usually adopt neutral point grounding way of three-phase three-wire power supply, improve the power supply reliability, reduce the line loss, increase the margin level of the distribution line, reduce the rate of tripping. But using three-phase three-wire power supply line in the actual operation of distribution network, the single-phase earth fault happens often, seriously affected the substation equipment and the safe and economic operation of the distribution network. Based on such fault is analyzed, and puts forward new on feeder terminal for such fault detection scheme.
