A. – 78.1 - j41.9. B. 93.4 – j77.8 C. 120.2 - j20.7 D. - 114.1 - j41.9 REE – April 2005 42. The loads on a 230-volt three-phase generator consist of (a) three groups of incandescent lamps, each group containing twenty 100 watts lamps and (b) a 9 hp motor operating at 82 percent power factor and 87 percent efficiency. Find the total load current in amperes. А. 30 В. 37 C. 40 D. 45
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.
