I have no idea what the 2nd part of post is stating, but a 240 3 phase to 480/277 wye is a common transformer. On the secondary (480/277) side you would ground the 277 v neutral terminal.
 
Depends a lot on the type transformer you are looking for.
Commercial/Industrial "standard" step-up/step-down/buck& boost here's one of many links:

GE & SquareD catalogs are full of all types.
