When fully loaded, a three-phase induction motor develops 500 hp. The motor is connected to a wye-connected transformer whose line-to-neutral voltage is 2400 V. Each motor terminal draws 100 A. Friction, windage, and other thermal, mechanical, and leakage losses are minimal. Most nearly, what is the motor’s power factor?
