in a steam turbine, it is the speed at which the turbine should not go above. some time they call it overspeed trip. because the turbine rotor and berings are not design for such high speed and is not capable to handle this huge cenerfugal forces. usually there is two type of trip system: Electronic and Mechanical. some Steam Turbins have both protaction system.

axial shift depends upon the gap between rotot blade and fixed blade , not on float
A speed wrench ratchets back and forth.
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.
Turbine rated speed varies mainaly on the factors of Generating frequency and means of coupling to generator (viz trough a gear box or directly coupled and no.poles in generator). For exmple a 50hz generting frequency and a bi-pole genarator the turbine speed is 3000RPM. The allowed speed rise also depends on turbine design and generator operational range. Generaly the speed rise is restricted to Maximum of 10% of the rated speed.

Use a tacometer drive the governor round with an electric drill and measure the speed the govenor trips. lift govenor speeds are factory set
What to do while tripping
