A turbine trip is the automatic safety shutdown of a power-generation turbine due to unexpected events. Due to the number of issues that may cause a trip, they are relatively common events. Although it can occur on any such turbine, the term is most often seen in the field of nuclear power.
Many events can cause a turbine trip, including:
In order to trip the turbine, inlet steam has to be removed from the feed. This is normally accomplished with dump valves that re-route the feed stream from the turbine inlet directly into the condensers.
