Transformer Question

[noone]

I have a three-phase transformer wired Delta/Delta with a 460v primary and
325v secondary.

If I were to re-wire the secondary so that the transformer is Delta/Wye,
what would my secondary voltage be.

I'm guessing that I'll will now have 325v to neutral and 562v(325 X 1.73)
leg to leg.

Or is it more complicated than that.

Are you sure that you can actually rewire the coils? Will your
company/customer take all liability for the change? Seems an risky thing to
do with insurance companies as pissy as they are today.

Thanks for input guys. The primary on the tranformer has various taps for
460,480,or 435. Either way 563 volts is way high.

While the manual for SCR drive say it can be fed from an ungrounded source,
the print for the rest of the unit shows a wye secondary with a the neutral
being used for chassis ground. With all the microprocessors and
communication wiring, the manufacturer wants the ground.

So the manufacturer is sending new transformers,(there fault anyways)
