By which one of the following we can measure the reliability of a string_____________?
Correct answer: D. Derating factor
- A. String efficient
- B. Reliability factor
- C. Factor of safety
- D. Derating factor
Explanation
The derating factor indicates how far a thyristor string is operated below its ideal rated capacity, allowing for unequal sharing and improving reliability. String efficiency mainly describes utilization, not reliability directly.
