Now that I'm getting some transformers to buck the voltage from my

phase converter I need to determine whether the output is wired wye or

delta. I think it's delta. but since it's a phase converter I just

don't know and need to be sure. According to the Square D website the

wiring is different between delta and wye when using the buck xmfrs.

Delta only needs two xmfrs for example. So how do I determine what I

have? I do know that leg to leg voltage is the same but that leg to

neutral for the manufactured leg is not. The two lines supplied by the

power company measure 124 volts to neutral and the manufactured leg to

neutral is 230 volts.

Thanks,

Leg to leg voltages should around 240 volts.

The generated leg should make the system look like an open Delta.

But the supply being Delta or Wye will not affect the transformers.
The transformers can however be wired int Delta or Wye....

IOW, you have a supply. It can be Delta or Wye.

Then you have the Buck/Boost transformers.
They can be wired in Delta or Wye.

Don't confuse the two things.
Well maybe I just don't understand. The Square D website has wiring
diagrams for both wye and delta SUPPLY according to my interpretation.
However, I'm pretty sure I have open delta.
