Practical dissection methods for rotating equipment insulation assessment

This paper will review methods of condition assessment and machine dissection for the viewpoint of practical needs and timelines. Prior to repairing rotating machines, it is important to gather information about the status of the insulation system. This can include testing programs to assess the condition of the insulation materials, but it also includes physical review of the entire piece of equipment. Once the initial testing is completed, it may be determined that the insulation system needs to be replaced or repaired. There are methods for the dissection of the device such that additional information can be learned as to the condition of the insulation materials. The timeframe for a repair, or the need to understand the condition of sister machines, can influence the motor dissection process.
