| Abstract: | This study proposes a new recovery power supply technology for the synonym phase two point to ground short circuit fault of the rural power network.It takes full advantage of the existing three-phase three element relay configuration technology.The synonym phase two point to ground short circuit would be greatly converted into the single phase to ground fault,on which the grid can supply in short time,and increases the non-effective grounding system of power supply reliability. |

| Keywords: | rural power network two points earthed faults quickly restore power supply |
