This presentation discusses the design of a high efficiency Pelton turbine. A Pelton turbine is an impulse turbine that works under high head but low discharge. It contains a number of buckets around its rim and its main component is the nozzle. The presentation outlines the key components of a Pelton turbine, including the distributor, housing, needle valve, runner, deflectors and turbine shaft. It also discusses the materials commonly used for buckets, nozzles and runners. Design calculations are presented for optimizing bucket dimensions. The presentation concludes with a discussion of efficiency but does not provide specific efficiency figures.
