A six pole,60 Hz synchronous motor is connected to an infinit bus of 15 KV through a transmission line.The synchronous reactance of the motor is 5 ohm ,and the inductive reactive reactance of the transmission line is 2 ohm .when Ef is adjusted to 16kV (line to line),the reactive power at motor's terminal is zero.
Calculate the terminal voltage and developed torgue of the motor?draw the phasor diagram of the system.
