Are there any advantages of using a 480-208/120 transformer versus a 7200 or 12470 volt primary transformer??? We're looking at a couple of 150KVA type K and about six 200KVA 208/120v standard xfmr's. Wouldn't the 12.47KV primary xfmr deal with load changes better than the 480V xfmr? Also, we would be able to cut down on supply amperage and physical size of the package with 12.47KV vs. 480v, right? Any thoughts??
