2015-1-14 · A virtual main system seeks to solve a typical arc flash issue – the high-incident energy typically present at the low-voltage side of a substation transformer – which would affect at least the low-voltage transformer compartment and the main section of the downstream switchgear and, at worst, the entire low-voltage switchgear/switchboard.

2013-10-16 · This standard has a much different method of assessing arc-flash hazards in outdoor substations. IEEE 1584 is not used. (BTW, the IEEE 1584 equations only cover up to 15 kV). Due to the relatively large bus spacings, arc-flash energy is based on an assumption of a line-to-ground fault only.
