Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Star-Delta-switch with arc when switch opens.If control is false, plug_sp and plug_sn are star connected and plug_sp connected to the supply plug.
If control is true, plug_sp and plug_sn are delta connected and they are connected to the supply plug.
Note there is a delay between opening star connection and closing delta connection, respectively opening delta connection and closing star connection.
