A 1-phase alternator has a nameplate rating of 380V, 60Hz. If the equivalent impedance of the alternator is 0.08+j0.5 ohm with power factor is at 0.8 leading and the no-load voltage is equal to the nameplate voltage, the current__________the no-load voltage by__________. a. lags, 16.27 degrees b. leads, 16.27 degrees c. leads, 79.7 degrees d. leads, 36.87 degrees
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.
