FFOV Analysis for 500 kV Substation

This is a presentation on lightning overvoltage analyses for a 500/220 kV substation. Highlights: An interesting application case where the electrical distance between the surge arrester and transformer was quite long, requiring us to check the adequacy of the surge arrester. Proper selection of lightning parameters in line with CIGRE TB063 (updated in 2021). We can provide some easy-to-use recommendations for lightning waveform modeling. Modeling of substation apparatus, including some brief guidelines and critical points not to miss.
