Multiple inlet system of air cooling of turbo-alternators can be used for machines of rating upto_______________?
Correct answer: C. 60 MW
- A. 10 MW
- B. 30 MW
- C. 60 MW
- D. 150 MW
Explanation
A multiple-inlet air-cooling arrangement improves the distribution of cooling air and is commonly used for turbo-alternators rated up to about 60 MW. Higher ratings usually require hydrogen cooling.
