To reduce short circuit fault currents are used_____________?
Correct answer: A. reactors
- A. reactors
- B. resistors
- C. capacitors
- D. none of the above
Explanation
Reactors add inductive reactance in series with the circuit, limiting the magnitude of short-circuit current. Resistors can also limit current, but reactors are preferred in power systems because their normal power loss is much lower.
