"And you are saying 160Kohm impedance of the IT as the R in this case."

I am not saying that. I never said that.

"I don't think Z(IT) is in series with the Shunt C at all in the IT circuits. It is effectively Rp."

Correct, if the IT is 1:1 then Rp is reflected to the secondary and Rp is the source impedance and the "R" used to calculate the effect of the Miller Capacitance.

But with a 1:4 winding ratio IT we have a 1:16 impedance ratio IT so "R" is Rp times 16. That's is what I have been saying.

BTW Transformers do not have impedances. They only have winding ratios.

Transformers are made to work with certain impedances. The inductance and winding capacitance dictate that and that is what the "impedance rating" of a transformer is all about.

But that is not to say that they have impedances of their own. They don't.

Transformers only "reflect" impedance according to their impedance ratio.

The "R" presented to the primary will reflect to the secondary and the "R" presented to the secondary will reflect to the primary.
