Consider a 3-phase transmission line operating at 66 KV and connected through a 1000 KVA transformer with 5% reactance to a generating station bus-bar. The generator is of 2500 KVA with 10% reactance. The single line diagram of the system is shown in Figure beside. Suppose a short-circuit fault between three phases occurs at the high voltage terminals of transformer. Suppose we choose 2500 kVA as the common base kVA. The fullt load current corresponding to 2500 KVA base at 66 kV in ampere is:

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.
