Intensive research effort has been focused on the Signature Analysis (SA) to detect electrical and mechanical fault condition of induction machines. Different sensors can be used: voltage, current, flux, power. In the case of current sensors (CSA) the interpretation of one-phase current spectrum or the three-phase current space vector spectrum provides direct information on the presence of abnormal conditions. With proper operative condition a similar interpretation can be obtained by using flux sensors (FSA). In this paper, in order to propose a diagnostic system oriented to wind turbine generators and in order to pass from wired systems to wireless systems, a suitable procedure will be studied.
