The manufacturer normally carries out a works overspeed proof test at 120%, well below the design limit at which failure could occur. The setpoint of the overspeed trip is such that this speed would never be exceeded even at the maximum acceleration rate of the turbine. Because of the delay time associated with the mechanisms, the finite response time of the valve relays and the stored energy in the form of steam and water within the turbine, it is logical to split the 20% range of 'available' overspeed equally between the governor and the overspeed trip. The stop valves (operated by the overspeed trip) and the governing valves will therefore have similar requirements for their maximum closure rates. The overspeed trip is set in the range of 110-111% speed. This recognises normal governor action over a ± 1% speed range.
