A power plant generates 40 MW of AC electricity. This power is to be transmitted to another city via a transmission line that has a resistance of 7.00 (to the city and back). (a) If the lost power along the line is 44 kW, what is the voltage of the transmission line? (b) If the ratio of the number of turns of the transformer's coils is 25, what is the current in the primary coil?

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.
