Question:

Consider a 140 km transmission line with a 127.5 MW, 210-kV, 60-Hz, 0.85-PF lagging, three-phase Y-connected. The transmission line resistance (R) = 0.09 Ω/km; reactance (X) = 0.88 Ω/km; shunt admittance (Y) = 4.1 × 10-6 S/km. The line voltage at the receiving end of the transmission line is 210 kV.

What is the transmission line efficiency at full load? Is it good? Ignore the admittance.
