🔍 Key Concepts

• Overspeed trip function and purpose on a turbine • How speed is sensed in rotating machinery (governors and trips) • Difference between mechanical/centrifugal action and fluid (pneumatic/hydraulic) control systems

💭 Think About

• Ask yourself: What physical change occurs directly as the turbine shaft spins faster than its safe speed? • Which listed force can act directly on moving parts attached to a rotating shaft without needing separate piping or control systems? • Which options are more likely to be part of control/assist systems rather than the primary, automatic overspeed sensing mechanism?

✅ Before You Answer

• Identify which force naturally increases with rotational speed of the turbine rotor. • Distinguish between a sensing mechanism (what triggers the trip) and an actuating medium (what might move the valve once triggered). • Eliminate any options that require an external supply system (air/oil/water) rather than being inherent to the spinning turbine itself.
