标准简介

适用范围：

This recommended practice outlines test procedures for comparing two or more unsealed or sealed insulation systems in accordance with their expected life at rated temperature. The procedure is limited to insulation systems for AC electrical machines using form-wound pre-insulated stator coils rated 15 000 V and below. The intent of this test procedure is to evaluate unsealed insulation systems for use with air cooling under usual (normal) service conditions, or sealed insulation systems for use… read more under severe environmental conditions (where the insulation is exposed to conducting contaminants). This procedure does not cover special requirements, such as those for machines enclosed in gas atmospheres or machines subjected to strong chemicals, metal dust or submersion in liquid, etc. The procedure includes instructions for testing candidate systems in comparison with known reference systems, of the same type, having a proven record of service experience and interpreting the results of these tests.
