3 Phase Losses in the transmission line
Per phase resistance of the transmission line
A 3-phase, 50 Hz, 35 km long overhead line supplies 500 kW at 22 kV, 0.8 p.f. lagging. The line resistance is 4 2 per
phase and line inductance is 10 mH per phase. Calculate the Reactance of the Line, Current flowing through the
transmission line, Sending end voltage, Voltage regulation and Efficiency of transmission.
