2. Consider a 60Hz/230V three phase power system feeding a 50kVA constant power load operating at 0.8 lagging power factor. Assume the angle reference to be 0 for the voltage (line-to-neutral)

of phase A. (a) Compute the complex power drawn by the load (b) Draw phasor diagrams for the three phase voltages (line-to-neutral) and currents. Specify the length of each phasor. (c) Plot, over one 60Hz cycle, the three phase voltages (line-to-neutral) and currents (d) Plot, over one 60Hz cycle, the instantaneous power for each phase (e) Plot, over one 60Hz cycle, the total three phase instantaneous power (f) What differences do you observe on the instantaneous power per phase as compared to the three phase instantaneous power? How does the three phase instantaneous power compare to the complex power computed in (a)?
