Q2. ( 25 pts ) A three-phase delta-connected load having an impedance of ( 6+j 15 ) Omega /phase is fed from a three- phase Y -connected voltage source through a three-phase line with an impedance of ( 0.02+j 0.1 Omega )/phase. If the line-to-line voltage of the load is measured to be 250-V(rms), answer the following questions: a) Find the power factor of the load. Also, state is it leading, lagging, or unity. b) Find the line current of this system. c) Find the line-to-line rms voltage of the voltage source. d) Find the real and reactive power generated by the three-phase voltage source. e) Find per-phase voltage drop on the three-phase line.
