Ever hear of Thevenin? You can model your transformer as an ideal voltage source in series with a resistance. It doesn't account for inductive effects,
Replace "resistance" with "impedance" and then it does take care of inductance. Thats right, Thevenin/Norton equivalents work for Ls and Cs too  . Your impedance will be a complex number with some real part and some complex part. But still, you have to know the inductance (leakage in particular) of the transformer and this can change with current applied so you will get a non-linear response to some degree... maybe noticeable and maybe not.
