Model Modelica.​Electrical.​QuasiStationary.​MultiPhase.​Examples.​BalancingStarBalancing an unsymmetrical star-connected load

Information

For the unsymmetrical load (resistor, capacitor and inductor) the parameters inductance L and capacitance C are chosen such way that the neutral current (see currentSensor0) is zero.

Model Modelica.​Electrical.​QuasiStationary.​MultiPhase.​Examples.​BalancingDeltaBalancing an unsymmetrical delta-connected load

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.
