Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This model represents the internal connections of the terminal box of an electric machine. The parameter terminalConnection is used to switch between star (terminalConnection = "Y") and delta (terminalConnection = "D") connection. The star point is a plug with mSystem = Electrical.Polyphase.Functions.numberOfSymmetricBaseSystems(m) phases, representing the star points of each base system; see Modelica.Magnetic.FundamentalWave.UsersGuide.Polyphase.
