Wavelet Analysis and Park's Vector Based Condition Monitoring of Induction Machines

Condition monitoring is an important issue in the maintenance of electrical machines. In the last years many methods of fault detection were cited in literature. Most of the newly proposed advanced methods are for on-line and non-invasive monitoring. This means that the faults can be detected already in their incipient phase during the usual work of the monitored machines. The aims of this paper is to make a brief review of two nowadays more and more frequently used induction machines' fault detection practices: the wavelet analysis based method and the Park’s vector approach.
