Package with interfaces for three-phase unbalanced AC models
This package contains connectors that are used by the models in the Buildings.Electrical.AC.ThreePhasesUnbalanced package. The connectors extends the basic connectors Buildings.Electrical.Interfaces.Terminal and define a new graphical icon in order to be distinguished by connectors of other electrical systems (e.g. DC systems).
Extends from Modelica.Icons.InterfacesPackage (Icon for packages containing interfaces).

This model represent a connection between wye to delta
Adapter from Wye (Y) to Delta (D) connector. A three-phase unbalanced connector has three AC single phase connectors. Each AC single phase connector contains the phase voltage, which is measured between the phase and the neutral. This model converts the phase voltage to the line voltage, measured between the phases.
The image below show how the phasors are computed when converting from Y to D.

This model represent a connection between wye to wye grounded
Adapter from wye (Y) to wye grounded (Yg) connector. A three-phase unbalanced connector has three AC single phase connectors. Each AC single phase connector contains a the phase voltage, which is measured between the phase and the neutral. This model assures that the voltage of the neutral cable is equal to zero.
