With direct water cooling it is possible to have ratings of about_____________?
Correct answer: D. 600 MW
- A. 200 MW
- B. 300 MW
- C. 400 MW
- D. 600 MW
Explanation
Direct water cooling removes heat very effectively from the conductors, allowing large turbo-generators to reach ratings of roughly 600 MW. Air and conventional hydrogen cooling generally impose lower rating limits for comparable machine sizes.
