Modeling 3-phase 3-limb star auto transformer w delta tertiary (YNa0d5)
I would like to create a UMEC model of a 3-phase 3-limb star auto transformer w delta tertiary (YNa0d5). I have the core dimensions, number of turns, losses, saturation, impedance data, etc.
As I understand, the 3-winding auto transformer from the master library is 3 single-phase banks and the UMEC and duality-based models do not support auto transformers. Is there any model available for what I am trying to do?
Also, I do not see any place to enter copper losses in the master library 3-winding auto transformer model but this field is present in the 2-winding auto transformer model. How can copper loss be modeled for a 3-winding auto transformer?
Thanks!

hey jary, recently I am developing code for 3-phase 3-limb YY transformer UMEC model, I think there are some similarities in our works, would you mind send me an E-Mail so that we can better discuss on this topic?
