Transformer impedance
Transformer impedance
(OP)
Hi, i need some help guys.
I have to simulate a transformer (DYn1) and i need as parameters the Zequal of winding 1, the Zequal of winding 2 and magnetization resistance and reactance. I have computed the R1,X1 for positive sequence(so negative) and R0,X0 for zero sequence, from known data. So the question is, how can i extract the data i need from Z1,Z0 that already known?

The inductive reactance of a coil is proportional to the square of the number of turns.
The primary and secondary are wound on a common core.
Will the ratio of the reactances be in the ratio of the square of the turns ratio?
So, will the reactances of a 480 Volt to 240 Volt transformer be 4:1 or 80% for the primary and 20% for the secondary.
