A 3-phase, 60 Hz, 40 km long overhead line supplies 475 kW at 11 kV, 0.9 p.f. lagging. The line resistance is 50 per phase and line inductance is 15 mH per phase. Calculate the Reactance of the Line, Current flowing through the transmission line, Sending end voltage, Voltage regulation and Efficiency of transmission.
