A town situated 20 kW away from a power plant generating power at 440 V requires 600 KW of electric power at 200 V. The resistance of two wire lines carrying poweris `0.4 Omega` per km. The town gets power from the line through a 3000-220 V step down transformer at a substation in the town. Find line power losses in the form of heat. How much power must the plant supply assuming that there is negligilbe power loss due to leakage ?
A. The loss in the form of heat is `640 KW`
B. The loss in the form of heat is `1240 kW`
C. Plant should supply `1240 kW`
D. Plant should supply `640 kW`
