1. A single-phase power system consists of a 480-V 60-Hz generator supplying a load of Zload = 4 j3 Ω through a transmission line of impedance Zline = 0.18 j0.24 Ω.(a) (i) If the power system is exactly as shown in Fig. P3.1, calculate the line current voltage at the load.(ii) Calculate the transmission line losses.(b) Suppose a 1:10 step-up transformer is placed at the generator end of the transmission line and 10:1 step-down transformer is placed at the load end of the line (see Fig. P1.2)
