. A 2300 V, With 2500 kVA three phase delta-connected alternator has a resistance of 0.1 ohm/phase and a synchronous reactance of 1.5 ohms/phase. The alternator is adjusted to rated voltage at no load. Calculate its terminal voltage when carrying rated current at no load power factor of 0.6 lagging.
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.
