Figure P2-1 shows a three-phase power system with two loads. The Δ-connected generator is producing a line voltage of 480 V, and the line impedance is 0.09 + j0.16Ω. Load 1 is Y-connected, with a phase impedance of 2.5Ð36.87° Ω and load 2 is Δ-connected, with a phase impedance of 5<-20° Ω.
(a) What is the line voltage of the two loads?
(b) What is the voltage drop on the transmission lines?
(c) Find the real and reactive powers supplied to each load.
(d) Find the real and reactive power losses in the transmission line.
(e) Find the real power, reactive power, and power factor supplied by the generator.
