A 550 volts, 55KVA single phase alternator has an effective resistance of 0.02 ohms, a field resistance of 10 ohms produces an armature current of 200 A on short circuit and an EMF of 450 volts on open circuit. What is the voltage regulation at full load and 0.80 lagging power factor
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.
