The target of this paper is to present an innovative signal processing tool to isolate and to identify the variations caused by a defect on a bearing outer ring. This tool is based on the reconstruction of a filtered version of IAS signal and it is applied on IAS measurements performed on an experimental test bench with artificial bearing defects and on an actual wind turbine.
