A small town with a demand of 800 kW of power at 220 V is situated 15 km away from an electric plant generating power at 440 V. The resistance of the two wire line carrying power is `0.5Omega`.`km^-1`. The line gets power from the line through a 4000-220 V step-down transformer at a substation in the town.
How much power must the plant supply, assuming there is negligible power loss due to leakage.

Text Solution

Verified by Experts

Power supplied by the plant=800+600=1400 kW
