Reliability test prototype wind turbine savonius type helical as an alternative electricity generator

The consumption of energy in the world today is still dominated by fossil fuels that will gradually run out. This period we must utilize renewable energy sources. One source of renewable energy that is environmentally friendly and we can use is wind energy. Wind turbines can be used to generate electrical energy so that it can solve one of the energy problems for people in need. A suitable wind turbine at low wind speed and medium wind speed is a type of Savonius turbine. The development of research is made prototype wind turbine. This test is carried out on a prototype of a vertical axis type wind turbine and aluminum flask. The rotor has a diameter of 350 mm and a height of 440 mm. The measured parameters were wind speed, rotation speed of rotor, voltage, and current of the generator. The performance of wind turbine savonius in this test at wind speed 4 m / s up to 6 m / s, maximum rotation of turbine shaft 35,40 rpm, electric power 6.94 watts at 6 m / s, at 6 m / s wind speeds produce wind power of 18.65 watts and produce electrical power of 6.94 watts.
