Modelica.Electrical.MultiPhase.Interfaces.PositivePlug

Information

Connectors PositivePlug and NegativePlug are nearly identical. The only difference is that the icons are different in order to identify more easily the plugs of a component. Usually, connector PositivePlug is used for the positive and connector NegativePlug for the negative plug of an electrical component.
Connector Plug is a composite connector containing m Pins (Modelica.Electrical.Analog.Interfaces.Pin).
