Impulse Water Turbine

Impulse water turbine (Pelton turbine or Pelton wheel) is the standard type of turbines that are widely used nowadays. It is also called a free jet turbine. Pelton turbine operates under the high head of water and therefore, requires a comparatively less quantity of water.

In this chapter, the components of hydro-electric power plants using this type of turbine are presented with neat sketches. Theory of power, all mathematical calculations using velocity diagrams, solutions for single or multi-sets, power regulation components, supply, and discharge systems are also presented. Finally, solved problems are illustrated in detail at the end of this chapter.

Keywords: Components of impulse turbine, Pelton turbine, Power regulation mechanisms, Supply and discharge system.
