A Pelton turbine is a hydraulic impulse turbine used in hydroelectric power plants with a high vertical head. The turbine was introduced in 1879 by the American carpenter and inventor Lester Allan Pelton, hence its name. Its operating principle reflects that of the classic noria (machine for drawing water from a well) with blades of old water mills, reworked to increase its efficiency: the water is transported to the penstock, which has a nozzle at the end, which is a closure that increases the speed of the water. The jet of water coming out of the nozzle hits the rotor blades, which are spoon-shaped. The Pelton turbine is used for large heads (between 300 and 1400 meters) and flows of less than 50 cubic meters per second, in order to obtain higher speeds.
