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.

(a) Determine the point of intersection of the line given by (x, y, z) = (4+t, −1+8t, 3+2t), t ∈ R with the plane given by 2x − y + 3z = 15 or show that they do not intersect.
