Abstract

In order to limit the induced voltage, 220kV high voltage single core power cable needs reliable grounding in the actual operation. Metal sheath will produce induction overvoltage when lightning intrudes the cable conductor. Inductive overvoltages can have a variety of adverse effects on cable performance. Through the lightning intrusion of single-core cable core conductor typical simulation of the situation, the influence of the cable arrangement, the distance between the shafts, the length of the cable, magnitude and character of cable loads on the overvoltage are studied. Simulation and discussion indicate that cable arrangement, the distance between the shafts, the length of the cable, magnitude and character of cable loads have different degrees of influence on metal sheath overvoltage.
