dentify the conditions to be satisfy for the synchroscope method of synchronizing an alternator. (i) The terminal voltage must be equal to the bus bar voltage. (ii) The frequency of the generated voltage must be equal to the frequency of bus bar voltage. (iii) The phase angle between the generated voltage and the voltage in the grid will be zero. Option 1: (i) & (ii) Option 2: Only (i) Option 3: Only (ii) Option 4: (i),(ii) & (iii)
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.
