Mechanical Overspeed Devicee

Synchronous generators are driven by different hydraulic turbines, which operate at different speeds. In case of load rejections (total or partial), the turbine-generator set overspeed may occur. In extreme cases, where the actuator isn’t closed quickly, the machine may reach dangerous speeds. To ensure process safety, the REIVAX MODX mechanical overspeed pendulum ensures fast closing of the main actuator.
