What is master fuel trip?

A master fuel trip is a safety mechanism in power generation systems, particularly in gas or steam turbines, designed to shut down the fuel supply to the turbines in the event of an emergency or malfunction. This action helps prevent accidents, such as fires or explosions, by quickly halting the combustion process. The master fuel trip is typically triggered by various alarms or protective devices that monitor operational parameters. Its proper functioning is critical for ensuring the safe operation of energy production facilities.
