L1 Power Plart T1 L2 City T2 L3 Question 8 A hydropower plant produce 100 MW of power at a voltage of 10 000 volts. L1, L2, L3 represent the transmission line and T1 and T2 the ideal transformer. The transmission lines are made of aluminium with a resistivity of 2.7*10-8 ohm meter and a cross-sectional area of 0.001 m². The transmission lines L1 and L3 are respectively, 0.5 km and 1.5km long. Given that the ratio of the number of turn from the first transformer is 20 (Ns/Np = 20), the voltage at the city is 10 000 Volts and the power consumed by the city is 80 MW find: (a) The power loss in L2. (b) The length of L2. (c) The ratio of the number of turn from T2.
