A turbine is tripped when ?
Correct answer: B. speed shoots up
- A. inlet pressure increase
- B. speed shoots up
- C. exhaust gets choked
- D. steam flow gets clogged
Explanation
A turbine is tripped by an overspeed protection system when its speed rises dangerously, preventing mechanical damage. Increased inlet pressure may cause overspeed, but it is the excessive speed that directly initiates the trip.
