I tried also with the same power and voltage in all three windings and nothing. I did this just to be sure that the impedances are reported at the same base.
Does anyone know if it is possible to determine the two winding equivalent of a three winding transformer with a load connected in the tertiary? I presume that the load and the tertiary must be 'absorbed' somehow into primary and secondary windings. From the leakage impedances, with delta-star...
