Information

The PowerTransformer is a two port. The left port voltage v1, left port current i1, right port voltage v2 and right port current i2 are connected by the following relations: 

      v1  = R1 *i1  + jωL_1s *i1  + R_Fe*jωL_h/(R_Fe + jωL_h)*(i1 + i2')
      v2' = R2'*i2' + jωL_2s'*i2' + R_Fe*jωL_h/(R_Fe + jωL_h)*(i1 + i2')
with:

      V2' = w1_w2*v2;  i2'=i2/w1_w2;  L_2s'=(w1_w2)^2*L_2s;  R2'=(w1_w2)^2*R2

This is the common way to describe power transformers.
All parameters have constant values.
