The control of a turbine with a governor is essential, as turbines need to be run up slowly, to prevent damage while some applications (such as the generation of alternating current electricity) require precise speed control. Uncontrolled acceleration of the turbine rotor can lead to an overspeed trip, which causes the nozzle valves that control the flow of steam to the turbine to close. If this fails then the turbine may continue accelerating until it breaks apart, often spectacularly. Turbines are expensive to make, requiring precision manufacture and special quality materials.

Answer / k.sankar

Governor has two valves one is TTV-Trip and Throttle
valve,second one is governor control valve.
Speed governors may used to control the speed of the steam
turbine.It's such a way set to operate with in minimum and
maximum speeds.
After opening the throttle valve the turbine develops speed.
After a certain speed attains the governor takes the control
and opens the governor valve to increase speed.

Answer / amar

speed governor gives the power to the turbine when the steam label goes down to its natural condition .

it store the power when the steam label is high and gives at require period
