I'm trying to figure out how to interpret a nameplate. Normally there pretty straight forward but even my Siemens rep isn't quite sure.
The transformer is a 13,200 primary, 480/240 secondary. We have the transformer connected for 480 secondary. It has a 55-65C rise. The kva rating, which is in question, reads 2500-2800/3333-3733.
Typically a 2,500 kva transformer rating goes up 30% with fans i.e. 3333. I don't understand how the 2800/3733 applies?
