Hello everybody !

I'm studying the magnetization of transformers. For this, I use the "Three-Phase Transformer (Two Windings)" block with parameters that seem correct. I select "Imag" in the parameters block and I check the results in a "Scope". Unfortunately, I don't obtain the expected signals and I don't understand why.

Somebody can help me ?

Thanks

If you are specifically looking for magentization, a simple transformer block will not capture the dynamics to the level of detail that you are looking for. You will need to use a higher fidelity transformer model.
