Frequency based wind turbine gearbox fault detection applied to a 750 kW wind turbine [PDF]
2014 IEEE Conference on Control Applications (CCA), 2014 Reliability and availability of modern wind turbines are of increasing importance, for two reasons. The first is due to the fact that power grids around in the world depends at a higher and higher degree on wind energy, and the second is the importance of lowering Cost of Energy of the wind turbines.

Detection of natural crack in wind turbine gearbox [PDF]
Renewable Energy, 2018 Abstract One of the most challenging scenarios in bearing diagnosis is the extraction of fault signatures from within other strong components which mask the vibration signal. Usually, the bearing vibration signals are dominated by those of other components such as gears and shafts.
