Components with simple SPICE models for Wye-Wye, Delta-Delta, and Wye-Delta transformers can be found in the attached Multisim files. The models are configured only by the turns ratio and the winding resistance parameters. With the exception of winding resistance, the models are ideal; there is no leakage inductance while core (or magnetizing) inductance is infinite.
These models can be useful for studying general behavior of three phase circuits, without complexities introduced by non-ideal behavior.
