摘要：

This paper calculates resonances in transformer windings, using a network of equivalent circuits, magnetically coupled. Inductive and resistive parameters of these circuits are calculated of a new form using vector fitting algorithm, through simulations and impedance measurement. It also includes a physical interpretation of the circuit model used, and the analysis of the importance of using frequency dependency of resistances and inductances.
