Balancing an unsymmetrical delta-connected load
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
For the unsymmetrical load (resistor, capacitor and inductor) the parameters inductance L and capacitance C are chosen such way that the magnitudes of the three-phase currents (see currentSensor12, currentSensor23, currentSensor31) are equal.
