Pelton Turbine is a Tangential flow impulse turbine in which the pressure energy of water is converted into kinetic energy to form high speed water jet and this jet strikes the wheel tangentially to make it rotate. It is also called as Pelton Wheel. Parts and Their Functions of Pelton Turbine Water turbines are critical in mankind's pursuit of clean energy. Among these, the Pelton turbine, inspired by the ingenuity of Lester Pelton, shines for its simplicity and power, which make it especially suitable for extracting energy from high-altitude water sources.

The Pelton wheel or Pelton Turbine is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel.

In this turbine, a high-velocity jet of water exits the nozzle and strikes the open air, subsequently impacting the specially designed buckets or vanes.

Pelton Wheel Turbine is the type of impulse or hydraulic turbine which is used for high heads for the generation of power. In this, the jet after leaving the nozzle runs in the open air and strikes the bucket or vane. The Pelton wheel turbine is developed by Lester Allan Pelton, who is an American Engineer. Figure 5.3.2.3 5.3.2. 3: The Pelton turbine also uses elements that act as "turnarounders" of water streams hitting them. They are called "buckets" and a number of them is mounted at the perimeter of the runner. The water jet hits the "ridge" in the bucket's center and is split into two streams that are both turned around (source. A Pelton turbine or Pelton wheel is a type of hydro turbine (specifically an impulse turbine) used frequently in hydroelectric plants. These turbines are generally used for sites with heads greater than 300 meters. This type of turbine was created during the gold rush in 1880 by Lester Pelton. [2] The design of a Pelton turbine starts with the dimensioning of the Pelton wheel, the choice of the rotational speed, and the determination of the number of injectors. To this end the following indications arising from the practical operations of Pelton turbines aid in establishing the design procedure:

Among different types of impulse turbines, Pelton wheel is the only turbine beingused at present. It was discovered in 188 0 by an American Engineer LesterA. Pelton. It operates under v ery high heads (upto 1800 m) and requires comparatively lesser quantity of water. Working principle of Pelton turbines From the head race in the mountains water.
A basic diagram of a Pelton turbine is shown in Figure 1, and a rotor (this is the so-called 'Pelton wheel') is shown in Figure 2. Diagram of Pelton turbine main parts In Figure 1 the penstock pipe delivers the water on the left-hand side. The turbine has been designed for the operational conditions of the Pelton test rig installed at the Waterpower Laboratory which is a horizontal single jet test rig with a jet diameter (ds) of 35.

Basic diagrams of a Pelton and Francis turbine are shown in Fig. 8. The dimensions of the Pelton turbine can be estimated if the runner speed (N), the net head (H) and water flow rate (Q). A Pelton wheel turbine is a tangential flow turbine in which the pressure energy of water is transformed into kinetic energy to form a high-speed water jet and this water jet hits the wheel tangentially to rotate it. An American developer Lester Allan Pelton invented the Pelton wheel turbine in the 1870s.
