A 12.4-kV single-phase generator supplies power to a load through a transmission

A 12.4-kV single-phase generator supplies power to a load through a transmission line. The load's impedance is Zload = 500/36.87 2, and the transmission line's impedance is Zline = 60/60. Vg=12440 KV Va=12440 kv. 1:10 T 60260 0 Zize (a) 60/6002 Zine 10:1 T 500L 36.87 2 Zload 500L 36.87 02 (a) If the generator is directly connected to the load (Figure P3-3a), what is the ratio of the load voltage to the generated voltage? What are the transmission losses of the system? (b) 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 (Figure P3-3b)? What are the transmission losses of the system now? (Note: The transformers may be assumed to be ideal.)
