Hydro Turbine

Pelton turbine also called a free-jet turbine or Pelton wheel, a
type of impulse turbine, named after L. A. Pelton who invented it
in 1880. Water passes through nozzles and strikes spoon-shaped
buckets or cups arranged on the periphery of a runner, which causes
the runner to rotate, producing mechanical energy. The runner is
fixed on a shaft, and the rotational motion of the turbine is
transmitted by the shaft to a generator. The impulse type turbines
are the best election for high head and small discharge hydraulic
power resources. They have compact structure, small size, high
efficiency and need fewer investments.They have been divided into
Turgo and Pelton type.
