Rotating electrical machines of various types and ratings are required for the operation of any industrial plant or power plant. Failure or breakdown of a rotating electrical machine can occur for various reasons at any time during the life of the machine. For any plant, the cost of downtime as a result of failure or breakdown of an electrical machine would be enormous. The costs of replacement of these machines often used for very critical operations, are quite exorbitant and the process of procurement very cumbersome. So, most of the times, the industry/power plant goes in for repair/reconditioning of their old machines.
