The SWT Field Lab allows to subject small wind turbines to extensive field tests. The infrastructure consists of ten foundations, six wind turbines, a meteorological tower, a measurement cabin and measurement equipment. Four foundations are available for services for companies active in wind energy. Not only the energy production of the turbine is analysed, but also topics such as noise production, generator design or mast construction are examined – all of this correlated with meteorological data such as wind speed and direction.
