An experiment was carried out in order to explore the mechanism of erosion of a small size Pelton turbine under actual flow conditions in the current study. Silt samples were taken from the head works of one of India's most silt-affected hydropower plants. The process of silt erosion on Pelton turbine buckets for different silt sizes was investigated using silt parameters (silt particle size and silt concentration). Hot areas were discovered in the initial half of the experiment when the silt content was high. The second phase of the experiment involved studying the erosion mechanism for tiny metal specimens that were fixed to the hot areas. According to the findings, silt size is a significant factor in erosion, and material removal from the surface is caused by plastic deformation and ploughing of the surface. Examination of different explanations for the decreased performance and efficiency of hydro turbines owing to silt erosions, as well as appropriate corrective techniques for such erosion offered by various scientists.
