Apparatus including in combination a turbine (1), a governor, a rotary device (11) and indicator means (14). The governor is adapted to govern the speed of the turbine by varying the pitch of the turbine blades (2) between their low-pitch position and their high-pitch position. The rotary device is connectable to rotate the hub of the turbine and thereby the blades, for testing the turbine, and the indicator means are adapted to indicate the attainment of the governed speed when the turbine is driven by the device and the power delivered by the device is increased beyond that which the turbine can absorb with the blades in the low-pitch position.
