The total power delivered to a balanced, Y-connected, three-phase load is 720 kW at a lagging power factor of 0.8. The line voltage at the load is 3463 V. The impedance of the transmission line is 2.5 + j10.2 ohm. a) Determine the line voltage at the sending end of the transmission line b) Determine the power dissipated in the transmission line. c) Determine the total power supplied by the source. d) Determine the load impedance per phase.
