摘要： A method of detecting faults in a wind turbine generator 150 based on current signature analysis is disclosed herein. The method includes acquiring a set of electrical signals representative of an operating condition of a generator 150. Further, the electrical signals are processed to generate a normalized spectrum of electrical signals. A fault related to a gearbox 140 or bearing 120 or any other component associated with the generator 150 is detected based on analyzing the current spectrum.

摘要： A method 300 implemented using a processor based device 180 includes obtaining 302 a measured electrical signal from an electrical device coupled to a mechanical device 150 and generating 304 a signal signature representative of a fault in the mechanical device 150 based on the measured electrical signal. The method 300 also includes determining 306 a diagnostic parameter based on a harmonic frequency of the signal signature and determining 314 the fault in the mechanical device 150 based on the diagnostic parameter.
