A small town with a demand of 800 kW of electric power of 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 The town gets power from the line through a 4000-220 V step-down trunsformer at a sub-station in the town
(a) Estimate the line power less in the form of heat.
A small town with a demand of 800 kW of electric power of 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 0.5 Ω per km.0.5 Ω per km. The town gets power from the line through a 4000-220 V step-down transformer at a sub-station in the town. How much power must the plant supply, assuming there is negligible power less due to leakage ?
