Electrical Engineering > GATE 2017 Set-1 > Synchronous Motors
A three-phase, 50Hz, star-connected cylindrical-rotor synchronous machine is running as a motor. The machine is operated from a 6.6 kV grid and draws current at unity power factor (UPF). The synchronous reactance of the motor is 30 Ω per phase. The load angle is 30°. The power delivered to the motor in kW is ____________. (Give the answer up to one decimal place).

Correct : 835 to 842
