A 60-Hz, 230-km, three phase overhead transmission line has a series impedance z = 0.85<78.04 ̊ /km and a shunt admittance y = 5.105 x 10-6 < 90 ̊ S/km. The load at the receiving end is 135 MW at unity power factor and 215 kV. Determine the voltage, current, real and reactive power at the sending end and the percent voltage regulation of the line.
