Extends from Ports.PortTrafo_p_n_n (Three port for 3-winding transformers).

Information

Terminology (formal).
  - index 1 (term_p) "primary"
  - index 2a (term_na) "secondary a"
  - index 2b (term_nb) "secondary b"

Transformer ratio.
The winding ratio is determined indirectly by the choice of nominal voltages.
It may be > or < 1.

Tap changers.
For constant transformer ratio no tap changer input needed.
For variable transformer ratio tap changer input needed.

The sequence of the parameters

  v_tc     tc voltage levels v_tc[1], v_tc[2], v_tc[3], ...

must be defined in accordance with the input-signals of 

  tap     index of tap voltage levels, v_tc[tap]

Set dynTC = true if tap-index changes during simulation.
