For which of the following protection from negative sequence currents is provided ?
Correct answer: A. Generators
- A. Generators
- B. Motors
- C. Transmission line
- D. Transformers
Explanation
Negative-sequence current produces a reverse-rotating magnetic field that causes severe heating in generator rotors, so generators commonly have dedicated negative-sequence protection. Motors can also be affected, but generator protection is the standard intended answer here.
