A balanced Wye-Delta three-phase power circuit has line-to-neutral source voltages of 220 V rms. The source angular frequency is 1000 rad/s, and the source voltages follow a negative phase sequence. The load impedances each consist of a 30 ? resistor in series with a 5 mH inductor. The line impedances can be modeled as a 1 ? resistor in series with a 0.5 mH inductor. (a) Draw a suitable circuit diagram representation of this power circuit. (use uploaded blank breadboard diagram) (b) Find the source line voltages and the line currents. (c) Hence find the current in each phase of the load. (d) Find the instantaneous power of the source, and the real and reactive power delivered to the load.
