Test example with polyphase components:
Star-connected voltage source feeds via a line reactor a diode
bridge rectifier with a DC burden.
Using f=50 Hz, simulate for 0.1 second and compare voltages and
currents of source and DC burden, neglecting initial
transient.
We may also compare: Active power measured by powerSensor,
powerSensorSpacePhasor and aronSensor, as well as reactive power
measured by powerSensorSpacePhasor and reactivePowerSensor.
