Hello,
I would like to take a small poll or begin a discussion on potential approaches to provide adequate PPE recommendations to personnel exposed to an arc flash hazard on metal-enclosed switchgear above 15-kV.

For industrial type facilities, I use EasyPower and it uses IEEE 1584 up to 15kV. Above 15kV, it uses Ralph Lee method.
For substations and utility overhead lines, I use ArcPro.

Didn't answer the poll, as I currently only work up to 2300 kV, with the exception of two 46kV/2.3kV utility transformers, and I don't model the primaries on those transformers.
