Abstract

Governor consists of a coaxial crown of suitable frictional material mounted within the the turbine box facing the blades. The material may be of graphite, or mineral powder or fibres mixed with thermosetting resin, e.g. glass fibres or asbestos mixed with phenolic resin. The governor limits the speed of the turbine to prevent breakdown due to excessive temperature.
