modelIMC_YDarc
Test example: InductionMachineSquirrelCage Y-D
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Same example as IMC_YD, but with a time delay between Y off and D on.
Note that a switchYDwithArc is used to avoid unphysical voltage peaks when opening Y connection.
Default machine parameters are used.
