This paper investigates a basic characteristic of fault surge in a long cable system based on EMTP simulations. It is made clear from the simulation results that the sheath over-voltage is higher on a cross-bonded cable than that on a normal-bonded cable. Also, a resonant overvoltage appears when cables with shunt reactors are disconnected. It becomes clear that the period of the beat becomes long as the compensation rate increases. From simulations with earth continuity conductor (ECC), the ECC is effective to reduce an overvoltage in the case of a fault at an overhead line connected to the cable. |
