The reliable diagnostic of non-adjacent rotor barbreakages in induction motors based on the analysis of currentsis still an unsolved industrial problem. The traditional MCSA hasnot proven to be robust enough for assessing the rotor conditionunder this situation; this is due to the fact that the joint effect ofbreakages located at certain relative positions can be subtractiverather than additive, leading to decrements in the faultharmonics amplitudes rather than incrementing them. This worktakes advantage of the potential of the novel FilteredPark’s/Extended Park’s Vector Approach (FPVA/FEPVA); thismethod has proven to overcome some constraints of thetraditional Park’s Vector-based methods: in this work, it isproven how this method can also reliably assess the rotorcondition even if non-adjacent breakages are present. The userfriendlyresults obtained with the method confer it a greatpotential for its future implementation in autonomous faultdiagnosis devices.
