Many years ago when we installed VFDs, we often used a drive isolation transformer. For the last 15 years or so, we have not being doing that.
I am looking at installing a 600 hp, 460 volt drive that will be supplied from a 2500kVA transformer in an industrial facility.. Most of the other load is across the line start motors with a few smaller VFDs and a couple of lighting transformers.
Is there any need for a drive isolation transformer or a line side reactor for this installation?
