.Modelica.Electrical.MultiPhase.Interfaces.OnePort .Modelica.Electrical.MultiPhase.Interfaces.OnePortSuperclass of elements which have two electrical plugs: the positive plug connector plug_p, and the negative plug connector plug_n. The currents flowing into plug_p are provided explicitly as currents i[m]. It is assumed that the currents flowing into plug_p are identical to the currents flowing out of plug_n.
