Single phase to three phase

[joshfromoshoto]

Am I able to connect 3 single phase control transformers to form a 3 phase wye connection? The source voltage would be 120/240.

No. With the "neutral" point of the primaries floating, the voltages would vary all over the place.

You are talking about the primaries, right?

Yes, my thought was to take 120 to the primary side or 3 single transformers, and connect them all to the same neutral. I'm not an engineer so I didn't know if there would be an issue with having 2 of the transformers on the same phase, so my next thought was to get a phase from a 120v generator haha. It's just an experiment I was going to try

As far as I know there is no way the make three phase (120 deg phase angle ) from split phase or pure single phase using just transformers. We typically use a phase converter, inverter, or a VFD to make three phase from single phase.

I didn't realize you only had 1ph.

No.

You need a phase converter.

Using two "phase conductors" and the neutral from a wye derived source however you could build a bank that has three phase open delta secondary.

Don't confuse him. He doesn't have that source.
