DESIGN OF PELTON TURBINE

The Pelton wheel is an impulse type water turbine. It was invented by lester Allan Pelton in the 1870s. 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 the Pelton turbine water jets impacts on the blades of the turbine. The turbine is used to rotate the wheel to produce torque and power.

PELTON TURBINE

• A tangential flow impulse type water turbine invented by Lester Allan Pelton.
• Useful turbine for hydro-power if water source has relatively high hydraulic heads and low flow rates.
• Most efficient among other impulse turbines with efficiency about 90%.
