ActiveElectrical insulation systems—Thermal evaluation of modifications to an established electrical insulation system(EIS)—Part 1: Wire-wound winding EIS
电气绝缘系统 已确定等级的电气绝缘系统（EIS）组分调整的热评定 第1部分：散绕绕组EIS
Application Summary AI generated
This standard specifies procedures for thermally evaluating modifications to established wire-wound winding electrical insulation systems (EIS), such as changes in materials or design. It is applied in the electrical engineering industry to qualify modified insulation systems for motors, transformers, and other wire-wound devices without requiring full re-qualification. The standard ensures that modified EIS maintain their thermal class rating under specified testing conditions.
