A small town with a demand of 1 MW at 220 V is situated 20 km away from an electric plant generating power at 440 V. The resistance of two line wires carrying is `0.5 Omega` per km. Two step down transformers are available : 4000 V - 220 V and 100000 V - 220 V at a substationin the town for supply of power. Which one will you prefer and why?

A small town with a demand of 800 kW of electric power at 220 V is situated 15 km away from an electric plant generating power at 440 V. The resistance of the two line wires carrying power is 0.5 Omega per km. The town gets power from the lines through a 4000-220 V step down transformer at a substation in the town. Estimate the line power loss in the form of heat. (b) How much power must the plant supply. assuming there is negligible power loss due to leakage? (c) Characterize the step up transformer at the plant.
