1. Refer to Figure 1. A Y-connected source supplies 3 balanced 3-phase loads. The source has voltage Vab-380 Z0v. d. What are the line currents (laa, IbB, lec)? e. What real, reactive and apparent power does the generator supply when the switch is closed? f. What are the line currents when the switch is closed? g. Determine the value of each capacitor when a Y-connected capacitor bank is to be connected in parallel with the loads to raise the PF to 0.95.
