A 3-phase, 11 kV, 10 MVA synchronous generator is connected to an inductive load of power factor

via a lossless line with a per-phase inductive reactance of 5

. The per-phase synchronous reactance of the generator is 30

with negligible armature resistance. If the generator is producing the rated current at the rated voltage, then the power factor at the terminal of the generator is
