Question
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 admittance is 315
micro-siemens. Shunt leakage may
be neglected.
Using the nominal T
approximation, calculate the
line voltage at the sending end
of the line.
