Switching overvoltages are the major concern with the cable system. For insulation coordination and design aspects one should know the range of this overvoltages. Different overvoltages and its effects on the system protection are described here. Some of mitigation techniques for switching transients are also listed. In this paper subsea cable system is considered for the simulation. Simulation has been done in PSCAD/EMTDC. By simulating different cases selection of rated impulse voltage for the equipments are defined.
