A short, three-phase subtransmission line has an impedance of 1.5 + j2.4 ohms/conductor. If the line serves at its end an induction motor rated 500 hp, 0.80 pf, 0.90 efficiency and 2,400 volts phase to neutral, determine the generalized circuit constants and use the results to find the sending-end voltage.
