At a hydroelectric power plant the water pressure head is at a height of 300 m and the water flow available is 100 m s If the turbine generator efficiency is 60 estimate the electric power available from the plant g 9 8 ms 2 A small town with a demand of 800 kW of electric power at 220 V is situated 15 km away from an electrie plant generating power at 440 V The resistance of the two wire line carrying power is 0 5 Q per km The town gets power from the line through a 4000 220 V step down transformer at a sub station in the town a Estimate the line power loss in the form of heat b How much power must the plant supply assuming there is negligible power loss due to leakage c Characterise the step up transformer at the plant Do the same exercise as above with the replacement of the earlier transformer by a 40 000 220 V step down transformer Neglect as hefore leakage losses though this may not be a good assumption voltage transmission involved
