Question 1 of 27070

Which of the following speed control devices is used strictly as a safety device to prevent prime mover damage and acts by shutting down the prime mover?

🔍 Key Concepts

• Overspeed vs underspeed protection on a prime mover (diesel, turbine, etc.) • Difference between a governor (controls/limits speed during normal operation) and a trip device (emergency shutdown) • Which device is used only for safety and not for normal speed regulation

💭 Think About

• Ask yourself: Which device would act suddenly and completely stop the prime mover when a dangerous condition occurs, rather than just adjusting fuel to control speed? • Which option is clearly described as an emergency protective device rather than part of normal speed control? • Think about what happens if a diesel or turbine runs too fast—what kind of device is installed to protect it from mechanical failure?

✅ Before You Answer

• Identify which choices are governors (continuous control) versus trips (on/off shutdown). • Determine which device is intended strictly as a safety device and not for normal speed regulation. • Confirm which device’s primary function is to shut down the prime mover when a dangerous speed condition is detected.
