A 72-kVA, 208-V, Y -connected, three-phase synchronous generator delivers the rated load at 0.866 pflagging. The armature winding resistance is 20 mΩ/phase. The core loss is 800 W. The friction and the windageloss is 350 W. The field winding is connected across a 120-V dc source and the field current is 5.5 A. Calculate the efficiency of the generator
