generator is rated 100 MVA at 11 kV, and 90% power factor. The effective ac resistance to ohmic resistance is 1.5. The resistance is obtained by connecting two terminals to a 12 volts dc source. If the current is 120 Amperes, What is the percent effective resistance per phase?
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.
