A 4.12 kV, 60 Hz, 3000-hp 0.8-PF-leading, Δ-connected, three- phase synchronous motor has a synchronous reactance of 1.1 per unit and an armature re at rated voltage with a line current of 300 A at 0.85 PF leading, what is the internal generated voltage per phase inside this motor? What is the torque angle δ?
