Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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.
