Problems 5-11 to 5-21 refer to a two-pole Y-connected synchronous generator rated at 470 kVA, 480 V, 60 Hz,

and 0.85 PF lagging. Its armature resistance RA is 0.016 &. The core losses of this generator at rated conditions

are 7 kW, and the friction and windage losses are 8 kW. The open-circuit and short-circuit characteristics are

shown in Figure P5-2.
