Magnetization resistance Rm and Magnetization inductance Lm of the Three-Phase Transformer

Simscape / Electrical / Specialized Power Systems / Power Grid Elements / Three-Phase Transformer (Two Windings)

Hello everyone,

do the values ​​Rm and Lm refer to the total values ​​of the three-phase transformer or do they refer to the single-pole equivalent circuit. I have not found any information about this in the documentation.

Thank you for your support!

Hi Torben,

The values of Rm (magnetizing resistance) and Lm (magnetizing inductance)refer to single pole equivalent circuit. These values are chosen to accurately capture the behavior of the transformer in the simulation environment. By incorporating these total values, the simulation can effectively model the transformer's magnetic characteristics and interactions within the power grid elements.I hope this answers your question.
