I understand that there is a bit of fudge factors involved, but I want
to know, approximately what size motors (with a usual load, like a
compressor or a lathe) can I start with a 45 kVA transformer feeding it.
No soft start of course.
Thanks
Hey Iggy,
Hammond (one of the "better" transfomer makers)
say that their 45kVA 3phase transormer is good for :
125 amps @ 208VAC (= approx. 50hp )
108 amps @ 240VAC (= approx. 40hp )
54.2 amps @ 480VAC (= approx. 20hp )
43.4 amps @ 600VAC (= approx. 15hp )
Take care.
