Abstract / Description of output

The reliable diagnostic of non-adjacent rotor bar breakages in induction motors based on the analysis of currents is still an unsolved industrial problem. The traditional MCSA has not proven to be robust enough for assessing the rotor condition under this situation; this is due to the fact that the joint effect of breakages located at certain relative positions can be subtractive rather than additive, leading to decrements in the fault harmonics amplitudes rather than incrementing them. This work takes advantage of the potential of the novel Filtered Park's/Extended Park's Vector Approach (FPVA/FEPVA); this method has proven to overcome some constraints of the traditional Park's Vector-based methods: in this work, it is proven how this method can also reliably assess the rotor condition even if non-adjacent breakages are present. The user-friendly results obtained with the method confer it a great potential for its future implementation in autonomous fault diagnosis devices.
