synchronous generator threewThe phases are rated at 1000 kVA and operate at a voltage of 6.6 kV. The product resistance per phase is 0.38 ohms and the leakage reactance is 0.5 ohms per phase. The generat works to provide full load at a power factor of 0.85 delayed and at normal voltages. Find the value of the no-load voltage.

Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
