State of art on condition monitoring of induction motors

Condition monitoring in industry is desirable for increasing machinery availability, reducing consequential damage, and improving operational efficiency. This is significant in industries employing heavy duty machines. Here, an attempt is made to demonstrate the various faults that occur in induction motors, and also to give an insight about the techniques that are used for corrective/preventive action for them. Main emphasis is given for the recent trends in fault diagnosis techniques to provide up-to-date information about the developments in this area.
