The per-phase synchronous reactance of a three-phase, wye-connected, 2.5-MVA, 6.6-kV, 60-Hz turboalternator is 10 . Neglect the armature resistance and saturation. Calculate the voltage regulation when the generator is operating at full load with (a) 0.8 power factor lagging, and (b) 0.8 power factor leading.

construction and its working
A 3-phase transmission line is 200km long. The line has a per phase series impedance of 0.25+j0.45 Ω/km and shunt admittance of j7.2 μS/km. The line delivers 250MVA, at 0.6 lagging
