🔍 Key Concepts

• Gas turbine protective systems and why automatic shutdowns are used • Typical overspeed, overtemperature, and fire protections in gas turbine modules • Difference between a condition that causes automatic shutdown and one that may be controlled/limited by other protections (like load control or pressure control)

💭 Think About

• For each option, ask yourself: would this condition be so dangerous that the system must immediately and automatically shut down to prevent major damage or fire? • Think about which parameters directly threaten the mechanical integrity of the turbine or create a fire hazard, versus which ones are usually handled by control/limiting rather than an instant trip. • Which parameter is more likely to be continuously adjusted/regulated during normal operation rather than only used as an emergency shutdown trigger?

✅ Before You Answer

• Identify which items are classic trip conditions: overspeed, overtemperature, and fire are common on many turbine systems. • Consider how compressor discharge pressure is normally managed on a gas turbine – does a high reading always mean an emergency, or can the control system modulate fuel/load instead? • Before choosing, separate parameters that protect from catastrophic failure or fire from those that are used mainly for performance/control.
