How Many Governors Are Needed For Safe Turbine Operation? Why?

1.	How Many Governors Are Needed For Safe Turbine Operation? Why?
Answer» 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. Two independent governors are needed for safe turbine operation.
