Q7.25 (a) A small town with a demand of of electric power at is situated away from an electric plant generating power at . The resistance of the two wire line carrying power is per km. The town gets power from the line through a step-down transformer at a sub-station in the town. Estimate the line power loss in the form of heat.
The total resistance of the two-wire line
RMS Current in the wireline
Power loss in the line
Hence, power loss in line is 600kW.
