# Nodal admittance matrix of a winding

I have a question concerning the nodal admittance matrix of a winding that has n turns. If each turn of the winding had its own model, is it possible to consider my winding a n-port network?

• You could probably ... if there were no "interaction" between the elementary model "1 turn"... Aug 1, 2022 at 10:58
• @Antonio51 By interaction you mean, couplings rights? -either capacitive ou inductive- Aug 1, 2022 at 11:13
• Yes. But if all these "couplings" are included in your "N-port model", you can define the base model for the "whole windings" (very complicated thing), not for a part (for each turn). Aug 1, 2022 at 12:55
• @Antonio51 I can easily define the base model for the winding (all turns included) but I am more interested in the turn behavior. I am more confused on whether I can define each turn as a port. I mean does is it physically make sense or it nonsense? Aug 2, 2022 at 7:48
• It does physically make sense ... But probably a "bit" complicated without checking at "lab". See my answer ... A try to modeling... Aug 2, 2022 at 17:03
