27/7/2021 · Sequential tripping of steam turbine generators. Abstract: The practice of tripping the generator breakers immediately following a boiler/turbine trip exposes a steam turbine generator to a potentially damaging overspeed operating condition. This paper describes the use of the sequential trip mode as a means of minimizing the exposure to
