isolation xfmr

[27hillcrest]

I need to purchase a 225kva transformer 480volt 208/120Y to feed an 800 amp main bypass panel for a UPS. Are all transformers isolation type? Thanks for the help!

NO.

Especially in this case.
The UPS manufacturer has much more detailed specs than simply an "isolation transormer". What specifically are they asking for, something like a noise isolation transformer?
