- Scope
- This standard specifies the evaluation method for the heat resistance of the insulation structure of high-voltage motors (3kV and above). The heat resistance evaluation method specified in this standard is based on the relative comparison between the tested structure and a reference structure with actual operating experience under the same test conditions. This standard is applicable to the heat resistance evaluation of high-voltage motor insulation structures.
