Unlike other types of turbines which are reaction turbines, the Pelton turbine is known as an impulse turbine.
This simply means that instead of moving as a result of a reaction force, water creates some impulse on the turbine to get it to move.
When used for generating electricity, there is usually a water reservoir located at some height above the Pelton turbine.
The water then flows through the penstock to specialized nozzles that introduce pressurized water to the turbine.
To prevent irregularities in pressure, the penstock is fitted with a surge tank that absorbs sudden fluctuations in water that could alter the pressure.
