Abstract

Power system is mainly affected by sudden changes in steady-state values of voltage and current, referred to as the transient phenomena, which are the result of lightning stroke or switching operation. The very fast transient overvoltages are generated due to switching operation. This fast front transient seen in gas insulated substation is one of the major concerns for its insulation coordination. In this paper, a 420 kV prototype model is developed and simulated using EMTP software. By operating a disconnector switch, VFTOs at various locations are analyzed. The severity of VFTOs is also analyzed by considering the trapped charge.
