2. A 4.12 kV, 60 Hz, 3000-hp 0.8-PF-leading, A-connected, three-phase synchronous motor has a synchronous reactance of 1.1 per unit and an armature resistance of 0.1 per unit. If this motor is running at rated voltage with a line current of 250 A at 0.8 PF leading, what is the per phase internal generated voltage in per-unit inside this motor? What is the torque angle 8? Solution:
