The designed RTV Power generation system is tested by blowing wind at different velocities. The set is welded to the top of an iron stand of 5 feet height for testing. Generated voltage is measured at an intervals of 25 rpm speed of the ventilator starting from 50 rpm. The maximum speed of ventilator is restricted to 150 rpm, since there is mechanical vibrations at 130 rpm and above, which might affect the system stability. For a RTV mounted on the roof, no such vibrations will occur at these low speeds. A maximum voltage of 30 V DC is obtained at a ventilator speed of 150 rpm. The generated voltage versus ventilator speed graph s depicted in figure 9.
