Trying to figure load calculations for 480-400v transformer. I got a peek at it on a walk-through and trying to do some homework in case I'm asked back. I believe it was a 83kva? Know the load is 125a 400v and they converted to 60hz from 50hz. Do I calculate line and load the same as a isolation transformer, this would be a buck/boost I believe... Thanks....-43 real feel here in Michigan, hope the van starts in the morning.
