Fault detection system and associated method

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.
