I want to simulate the no-load loss of a 3-phase transformer, how can I calculate the resistance or fill in the necessary information here?
I simulate a 50kVA, 15/0.4kV transformer

Hello Minh,

The resistance represented here is the dc resistance of the winding and inductance is the stray inductance of the coil. In case you use voltage as the type of excitation the resistance and inductance informaition has to be provided. If you are doing a 3D simulation the inductance of the coil can be calculated by the tool so the stray inductance part can be kept as zero. 

For the computation of the resistance you can use eddy current solver for the analysis.
