In the present study, simulations of the lightning overvoltages propagation phenomenon in a typical 380 kV SF6 gas‐insulated substation are presented. Influence of surge arresters installation on maximum‐generated overvoltage peak values is illustrated. A new overvoltage mitigating passive device in a form of a high‐voltage (HV) L–C filter is proposed. A process of its development and research is explained along with a simulation results. As demonstrated, the proposed device can be used in HV networks as an alternative or additional improvement for lightning overvoltages mitigation purposes. All simulations have been conducted using Matlab Simulink as well as EMTP/ATP software packages
