Abstract

The 550 kV gas-insulated substation is designed in the electromagnetic transient program (EMTP-RV) which simulated the design when the disconnector switch is operated. The operation of disconnector switch induces the VFTOs within a few nanoseconds, and the currents associated with VFTOs produce the electromagnetic fields. To reduce the very fast transients in the system, the mitigation techniques are to be implemented. In this paper, to reduce very fast transients in the system, the ferrite rings are installed at the disconnector switch. And it also have the impact on spark resistance and transformer entrance capacitance which will reduce the overvoltages.
