Abstract :
A maintenance inspection program making available manufacturer´s experience is described. General service experience with high-voltage machine insulation is reviewed. Several specific field problems are discussed. Likely failure causes are found to result from disturbance to the physical integrity of the insulation rather than a gradual deterioration caused by sustained electric stress. Inspection procedures, testing techniques, and equipment available in connection with the program are outlined.
