A balanced load of 30 MW is supplied at 132 kV, 50 Hz and 0-85 p.f. lagging by means of a transmission line. The series impedance of a single conductor is (20 +j52) ohms and the total phases-neutral admit- tance is 315 microsiemens. Shunt leakage may be neglected. Using the nominal T approximation, calculate the line voltage at the sending end of the line. If the load is removed and the sending end voltage remains constant, find the percentage rise in voltage at the receiving end.
