Simply short-out all the windings on one leg, probably one of the outside
legs to keep the flux path shorter. Then the two legs left will get all the
flux and behave like a single-phase transformer. Phase the two windings
remaining remembering that the flux circulates in a loop around the
remaining legs.
I have done this with my power distribution system and have found very low
loss in the now single-phase transformers.

Subject: [Amps] single phase into 3 phase transformer
What is the preferred method to wire a 3 phase transformer to operate off of
single phase?
I have heard of several possibilities and happen to have a mess of multi kW
three phase HV transformers.
