Popis: The modeling of single core cable has an important influence on the calculation of cable sheath cross-connected grounding current and voltage. A suitable equivalent circuit can greatly reduce the complexity of the model. In this paper, the theoretical calculation of π type equivalent circuit of cable is analyzed, and the equivalent circuit of cable sheath grounding system is analyzed. Then the calculation equation of sheath circulation and induced voltage is obtained. Finally, by simulating two kinds of sheath grounding faults, two kinds of sheath grounding fault location are summarized.
