Dear Engineers.
Greeting.

I want to do the Incident Energy calculations for 33 KV GIS switchgear & 66KV / 120 KV / 220 KV Load Break switch in the Outdoor switchyard ( Transmission line Power entering in the outdoor open air switchyard ).

What is the best method to calculate ? Because I know that IEEE-1584 2018 can not be used.

Please advise.
Thanks.
Mubin / Africa.

For HV equipment like 33 kV GIS and 66–220 kV outdoor switchyards, IEEE 1584-2018 typically isn’t applicable. Many engineers instead reference IEEE 1584 Annex D, EPRI, or CIGRÉ guidance for transmission systems, considering arc current, protection clearing time, and working distance.

I'm seeking advice on Incident Energy calculations for high voltage switchgear. Specifically, I'm dealing with 33 KV GIS switchgear and 66KV/120KV/220KV Load Break switches in an outdoor setting. I know IEEE-1584-2018 isn't applicable here, so what is the recommended approach? This feels like navigating Granny's house – you know something's there, but finding the best path is tricky! Any input would be greatly appreciated.
