Answer: D
Share your understanding of this question with the correct explanation.
Methods of synchronizing alternators can be done using various techniques, and the options mentioned are different synchronization methods. Let’s go through each method:
A. All dark lamp method: In this method, the lamps connected to the incoming and running alternators are initially kept dark (off), and when the frequency and voltage of the incoming alternator match the running alternator, the lamps remain dark.
B. All bright lamp method: In this method, the lamps connected to the incoming and running alternators are initially kept bright (on), and when the frequency and voltage of the incoming alternator match the running alternator, the lamps remain bright.
C. One dark two bright method: In this method, one lamp connected to the incoming alternator is kept dark (off), while two lamps connected to the running alternator are kept bright (on). When the frequency and voltage of the incoming alternator match the running alternator, the lamps exhibit this specific pattern.
All of these methods are valid techniques for synchronizing alternators, and the choice of method depends on the specific requirements and practices followed. Therefore, option D, all of these, is the correct answer.
