Entegrity Wind Systems's EW50 Turbine Testing and Results

Entegrity Wind Systems' EW50 wind turbine. Text Version

As part of the National Renewable Energy Laboratory and U.S. Department of Energy (NREL/DOE) Independent Testing project, NREL tested Entegrity Wind Systems' EW50 turbine at the National Wind Technology Center (NWTC). The EW50 is a 50-kilowatt (kW), three-bladed, horizontal-axis downwind small wind turbine. The turbine's rotor diameter is 15 meters, and its hub height is 30.5 meters. It has a three-phase induction generator that operates at 480 volts AC.
