| Abstract: | This paper makes theoretical analysis about fault orientation of single-phase grounding in railway 10 kV distribution network,summarizes the detection method of single-phase grounding fault,and proposes a new detection method of ground fault based on the prineiple of special signal injection.It also discusses in-depth the system configuration and working principle of this new method,which can make the railway dispatching and directing center automatically detect the fault orientation of single-phase groundi... |
