Scope

This standard specifies the method for evaluating the heat resistance of the insulation structure of high-voltage motors with a voltage of 3 kV or higher. The heat resistance evaluation method specified in this standard is based on a comparative analysis of the tested structure and a reference structure with actual operating experience under the same test conditions.
This standard applies to the evaluation of the heat resistance of the insulation structure of three-phase AC rotating motors with a voltage of 3 kV or higher.
