| Abstract: | The correctness of fault line selection device is very low because of the complex single-phase-to-earth fault in distribution network,which affects the reliability of power supply.Consequently,the principle of fault line selection under the arc-suppression coil parallel connecting the mid-resistance grounding was analyzed,and used in practice as the principle of fault line selection device,achieved well results,and improve the reliability of power supply. |
