Information

Modification of YDport_p for switcheable Y-Delta transform.
Defines Y- and Delta-topology transform of voltage and current variables.
The neutral point is isolated.

Definitions

  v:     voltage across conductor
  i:     current through conductor
  v_n:   voltage neutral point if Y-topology
  i_n=0: current neutral to ground if Y-topology

Relations Y-topology, (v, i: terminal to neutral point)

  v = term.v - {v_n, v_n, v_n}
  term.i = i
  i_n = sum(term.i)

Relations Delta-topology, (v, i: phase terminal to phase terminal)

  v_cond = v_term[{1,2,3}] - v_term[{2,3,1}]
  i_term = i_cond[{1,2,3}] - i_cond[{3,1,2}]
