This is my first post to this forum and hope to be involved often with what seems as an awesome group of problem solvers.
I am an Eng Tech at a Precious Metal Fabricator and leading the purchase of a CNC Lathe. We had a building expansion approx. four years ago and there were two Hi Leg 240v 3ph 150kVA transformers installed. The primary is 480 and the secondary is 240vac. Every other transformer throughtout the plant is a delta-wye, where these are delta-delta w-hi leg. This will be the first use of these "new" transformers and i would like to know the implications of their use. Several CNC manufactures of machines we do have, have said not to use them, but the manufacture of the CNC that I have purchased has not responded as of yet. The local transformer rebuilder has said to "just remove the tap that is grounded"...is this a reasonable thing to do? Is there really no issue at all?
I appreciate any and all help that I recieve...
Thanks...
