Parameters
Modelica Standard Library
The Switch YD with Arc (or Star-Delta Switch with Arc) component uses the Switch YD component with an arc when the switch opens. If the control input 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.
