The typical value of SCR for modern alternator is____________?
Correct answer: B. 0.5.
- A. 1.5.
- B. 0.5.
- C. 1.0.
- D. 1.2.
Explanation
Here SCR means short-circuit ratio, not silicon-controlled rectifier. Modern alternators commonly have a short-circuit ratio of about 0.5, reflecting their relatively low synchronous reactance margin.
