A 1MVA, 11 KV, three phase wye-connected synchronous generator has a synchronous reactance of 5 ohms and a negligible reactance per phase. At a certain field current the generator delivers rated load at 0.9 lagging power factor at 11 KV. For the same excitation, what is the terminal voltage at 0.9 leading power factor full-load?
