SystemModel["Modelica.Electrical.QuasiStationary.MultiPhase.Examples.BalancingStar"]
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 neutral current (see currentSensor0) is zero.
