modelThreePhases
Example that provides a comparison between AC one phase and three-phase balanced
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model illustrates the use of the impedance models and how the three-phase balanced model can reproduce the same results obtained using three separate one phase circuits.
