A transformer circuit which accounts for magnetization and core losses is presented in the following figure.
Voltage, Vin, is applied to the transformer primary side coil which consists of a series resistance and inductance, R1 and L1. The secondary side coil of the transformer is also modeled as a series resistance and inductance, R2 and L2. The magnetization and core losses in the core of the transformer are modeled with Lc and Rm. The impedance diagram for the transformer is created by replacing each element of the circuit with its associated impedance. The impedance of each resistance, Ri, is denoted as ZRi, and the impedance of each inductance, Li, as ZLi.
Draw the impedance diagram for the transformer system.
