Equivalent Circuit of identical transformers connected in parallel or series
For an ideal transformer (no saturation) one could combine the inductance's of some elements by paralleling the T-models.

T-models in parallel are reducible as the primary and secondary are in series with both mutual inductance's of each T-model, and the whole thing reduces to another T-model.

The series model would be reducible if one used Kirchhoff's laws, I am uncertain if it could be reduced to a T-model.
