This standard specifies the method for assessing the heat resistance of insulated structures of high voltage motors of 3 kV and above. The evaluation method is based on the relative comparison of the tested structure and the reference structure with practical operation experience under the same test conditions. Applicable to the evaluation of the heat resistance of insulated structures of three-phase AC swirl/spin motors with voltage classes of 3 kV and above.
