A 3-phase, star-connected alternator supplies a delta connectedload, each phase of which has a resistance of 15Ωand inductive reactance 20Ω. If the line voltage is 400V, calculate (a) the current supplied by the alternator and (b) the output power and kVA ratingof the alternator, neglecting any losses in the line between the alternator and the load.
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.
