A three-phase, 60-Hz transmission line has a total series impedance of 22.86 62.3° Ω per phase. It delivers 2.5 MW at 13.8 kV to a load connected to its receiving end. Compute the sending-end voltage, current, real power, and reactive power for the following conditions:
(a) 0.8 power factor lagging.
(b) Unity power factor.
(c) 0.9 power factor leading.
