The few fields texts that do the analysis for a shunt limited
transformer also show the shunt producing an effective series
inductance, so this is as it should be. Could you describe the
setup you used to separate out the resistive and inductive
parts? Since the inductance is kind of a virtual thing, inside
the fields of the transformer iron, as it were, I've never
come up with a really good way of measuring it.
