The main objective of this study is to validate the performance characteristics of newly developed micro propeller turbine based on experimental model test. For this purpose, Measurements of efficiency and cavitation tests with variations on the guide vane opening, blade rotational speed, head and load are carried out according to the IEC standard for model testing. From the tests and scale up calculation, the maximum prototype and model efficiency of the runner blade reaches as high as 90.87 % and 90.27 % respectively. Test results show that good cavitation behavior is covered in the range of output 50kW and 100 kW.
