A synchronous motor is rated at 100 kVA. The motor is connected to an infinite bus of 5 kV. The synchronous reactance of the motor is 0.1 ?. The motor is running at a no-loading condition (real power output is zero). All losses can be ignored. Calculate the equivalent field voltage Ef that operates the motor as a synchronous condenser delivering 100 kVAR to the infinite bus. Draw the phasor diagram. (A synchronous condenser produces reactive power and no real power.)
