by means of hydraulic turbines
Hydroelectric turbines The hydraulic turbine is that mechanical device that transforms the potential and kinetic energy of water into mechanical energy. It essentially consists of a fixed member called the distributor and a movable member called the impeller. The first has three essential tasks:
it directs the incoming flow to the impeller by giving it the due direction, regulates the flow by means of partialisation devices, causes a partial or total transformation into kinetic energy of the pressure energy possessed by the flow.
The extent of this transformation is the most important element for the classification of turbines: when the transformation from potential to kinetics takes place completely in the distributor, we speak of action turbines, otherwise of reaction turbines.
Finally, the impeller transforms the potential and / or kinetic energy of the water into mechanical energy rendered on the motor shaft.
