Beschreibung
Zusammenfassung:	Various embodiments of the present invention are provided for automatically testing an overspeed protection system of a powerplant machine comprising a shaft (137) and integrated with a safety control system (190). An embodiment of the present invention may automatically test the overspeed protection system while the powerplant machine is in the process of shutting down. Another embodiment of the present invention may automatically test the overspeed protection system of the powerplant machine by adjusting the speed of a shaft (137) while operating at full-speed-no-load.
