Question: 3 a 132kv singlephase generator supplies power to a load...

Question details

3. A 13.2-kV single-phase generator supplies power to a load through a transmission line. The loads impedance is Zoad-500 36.87 0, and the transmission lines impedance is Zine-60 53.1° Ω. (a) If the generator is directly connected to the load (Figure below), what is the ratio of the load voltage to the generated voltage? What are the transmission losses of the system? If a 1:10 step-up transformer is placed at the output of the generator and a 10:1 transformer is placed at the load end of the transmission line, what is the new ratio of the load voltage to the generated voltage? What are the transmission losses of the system now? (Note: The transformers may be assumed to be ideal.) (b)

60 53.1° Ω Zline VG-13.240 kV 500 L 36.870 Ω | Zud 60 53.1°Ω Zine 1:1010:1 500 L 36.82° Ω Zload vG 13.240 kV
