Impedances in transformers

[K&amp#305z&amp#305]

Hi, I have a question about impedance in transformer? Can you help me?

Thanks

impedance is very complex value, it depends on resistance and capacitance and inductance,these values are variational at difference frequency, it is good way if you can test impedance, you maybe find testing vaule is not big difference from theory value, special in high frequency.

Ideally impedance is zero in transmission but practically it is distributed over the whole transmission line and changes per unit of length.
some times we considered it as a concentrated impedance for our convenience.

Total Impedance =(Resistance+Inductance)||(Capacitance||Condactance)
