Correct, it make sense. But because in reality harmonics exist and are growing with increasing power electronics. So if someone want to model transformer, specially for harmonic studies. Than the generic model is not enough. For example capacitance between windings should also be considered. But...

Why transformer core is modeled as resistance even though it is frequency dependent.With increasing frequency current rises. Doesn't it seem capacitive reactance behaviour? Which decrease with increasing omega?

Thanks for your reply. I am using DigSilent PowerFactory software for modelling and simulation. I would like to explain more that which approach i am using. For MV cable: PowerFactory suggest to model cables based on geometric data for harmonic analysis. I will be inserting all geometric data...

Thanks for your reply. I contacted the manufacturer but its been more than a week, didnt hear from them. My supervisor in university said you can ask on forums and can approach other manufacturers also. Actually this data was to be provided by my research institute where i am working as they...

For my research project, modelling is needed for dyn5 630 kVA transformer and 20 kV cable NA2XS(F)2Y to do harmonic analysis. For that i need leakage reactance, and resistance of copper losses for transformer. And following parameters for 20 kV cable are also needed. Positive, negative and...
