I have bought a 3 phase 45 kvs transformer 480 - 240.

Since I buy and sell industrial equipment, I will be sure to come
across 460v only machines. So, I thought, I could use this transformer
to make 460v from 230v, which is what my building has.

So, realistically, can it be used in reverse? to make 460v.

you sure can, but may need to fiddle with the taps to get the voltages
right.

OK, thanks.

I have another question. I bought a 50 HP rotary screw compressor for
resale. I want to test it.

I realized today that it is 460v. Would this 45 kva transformer, be
able to run this compressor UNLOADED, just as a power up test -- not
pumping at full PSI.

Thanks

No. Startup surge will eithe pop the fuses..or take out the windings of
your motor in the RPCoverter.

One could not be a successful Leftwinger without realizing that,
in contrast to the popular conception supported by newspapers
and mothers of Leftwingers, a goodly number of Leftwingers are
not only narrow-minded and dull, but also just stupid.
