## Buildings.Electrical.AC.ThreePhasesBalanced.Interfaces

Package interfaces for three-phase balanced AC systems

### Information

This package contains connectors that are used by the models in the Buildings.Electrical.AC.ThreePhasesBalanced package. The connectors extends the basic connectors Buildings.Electrical.Interfaces.Terminal and define a new graphical icon in order to be distinguishable from connectors of other electrical systems (e.g. DC systems).

Extends from Modelica.Icons.InterfacesPackage (Icon for packages containing interfaces).

### Package Content

Name | Description
--- | ---
Terminal_n | AC three-phase balanced terminal ('negative')
Terminal_p | AC three-phase balanced terminal ('positive')

## Buildings.Electrical.AC.ThreePhasesBalanced.Interfaces.Terminal_n

AC three-phase balanced terminal ('negative')

### Information

Electric connector with a vector of negative pins.

Extends from Buildings.Electrical.Interfaces.Terminal (Generalized electric terminal).

### Parameters

Type | Name | Default | Description
