On a current inspection, sometime in the distant future I will get a set of engineered drawings but I would like some preliminary input from you knowledgeable guys.
I have a 2000kva transformer 480/277 supplying (5) 400 HP motors controlled by soft-starts.
My SCA at the transformer is 43K. Individual services to each soft-start.
.SCA at the end of each service is about 31K. Approximately what will my motor contribution be ?
(do the motors on the other services effect the SCA on the one individual service, etc.)
