Single-Phase Fault Line Selection in Distribution Network Based on Signal Injection Method
IEEE Access, 2021 The distribution network with small current grounding mode can ensure high power supply reliability, but it is difficult to locate single-phase grounding fault line. Most of the faults in distribution network are single-phase to ground fault.

Fault-line selection and fault-type recognition in DC systems based on graph theory [PDF]
Protection and Control of Modern Power Systems, 2018 When a fault occurs in a DC system, the fault current rises rapidly with no zero-crossing point which makes fault-line selection and fault-type identification difficult. In this paper, an online detection and protection method based on graph theory, namely the “double D method”, is proposed for fault-line selection and fault-type identification in DC ...
