The Pelton turbine is a type of impulse turbine used for generating electricity from high-pressure water sources. It consists of a wheel with spoon-shaped buckets around its circumference. As water jets strike these buckets, they cause the wheel to spin, converting the kinetic energy of the water into mechanical energy. This turbine is particularly effective in mountainous regions where water can be harnessed from high elevations. The design allows it to operate efficiently with low flow rates and high heads, making it a popular choice for hydroelectric power plants that utilize steep gradients.
