Electrical power is to be transported efficiently from a voltage source with v3(t)=100/2 cos(2r60 t) V through a transmission line of impedance 0.1 + j0.1 N to a load of Z, = 2 +j3 N using an ideal distribution transformer with a = 10 (ratio of turns) and an ideal unit transformer with a' = 1/20 (ratio of turns). a) Draw a schematic diagram of the network. Each transformer should be placed properly in the circuit. b) Find the real power of the load. c) Determine the power efficiency of the system.
