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 wirelines carrying power is 0.5 per km. The town gets power from the line through a 4000-220 V step-down transformer at a sub-station in the town. The line power loss in the form of heat is:
1. 100 kW
2. 500 kW
3. 400 kW
4. 600 kW
