Abstract
A process and apparatus for preventing the overspeed of a low head hydroelectric generating set including a turbine having an adjustable distributor valve assembly and adjustable vanes wherein the openings of the valve assembly and vanes are continuously monitored relative to one another and with the openings of the valve being limited by a conjugation device so as to insure that the pressure head through the turbine is retained at or just slightly below the normal lowest operating pressure head for which the turbine is designed to operate.
