2-3. Consider a simple power system consisting of an ideal voltage source, an ideal step-up transformer, a transmission line, an ideal step-down transformer, and a load. The voltage of the source is The impedance of the transmission line is Zline = 3 + j4 and the impedance of the load is Zload = 30 + j40

(a) Assume that the transformers are not present in the circuit. What is the load voltage and efficiency of the system?

(b) Assume that transformer 1 is a 1:5 step-up transformer, and transformer 2 is a 5:1 step-down transformer. What is the load voltage and efficiency of the system?

(c) What transformer turns ratio would be required to reduce the transmission line losses to 1% of the total power produced by the generator?
