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. |
