A Y -connected generator supplies a A-connected load through a transmission line. The generator line voltage is 480V. The load impedance (in each phase) is 30224° N. The line impedance is 0.01 + j 0.07 N. (a) Calculate the load impedance for the equivalent single-phase circuit for the above system. (b) Calculate both phase and line voltages at the load (complex voltage). (c) Calculate the total three-phase real and reactive power consumption for the load.
