2.A DC series generator is supplying a current of 8 A to a series lighting system through a feeder of total resistance of 2 Ω. The terminal voltage is 2500 V. The armature and series field resistances are respectively 20 and 10 Ω, respectively. A 15-Ω diverter resistance is shunted across the series field. Determine the power developed in the armature of the generator.
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.
