How many governors are needed for safe turbine operation? Why?
Correct!
Wrong!
Two independent governors are needed for safe turbine operation: One is an over speed or emergency trip that shuts off the steam at 10 percent above running speed (maximum speed). The second, or main governor, usually controls speed at a constant rate; however, many applications have variable speed control.
