A decrease in efficiency can be observed in many small water power plants due to pollution by leafs or floating objects. This project is carried out in order to investigate how these interferences influence the efficiency. The decrease in efficiency measured in tests with different test objects amounted up to 3 %. This magnitude may appear insignificant. However, it must be taken into consideration that these are basic investigations. First it had to be investigated how efficiency is affected by a leaf that turns around a running wheel blade. Problems occurring in practice with pollution by leafs may result in considerable generation losses. In the frame of a questionnaire survey among operators of power plants with pipe turbines 67% of 54 ...
