Overfluxing protection is recommended for_____________?
Correct answer: B. generator transformer of the power plant
- A. distribution transformer
- B. generator transformer of the power plant
- C. auto-transformer of the power plant
- D. station transformer of the power plant
Explanation
Overfluxing protection is especially important for the generator transformer because excessive volts-per-hertz can saturate its magnetic core and cause severe heating. The protection responds to an excessive V/f ratio rather than simply to overcurrent.
