ActiveElectrical insulation systems—Thermal evaluation of modifications to an established electrical insulation system(EIS)—Part 2:Form-wound 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2部分：成型绕组EIS
Application Summary AI generated
This standard specifies procedures for thermally evaluating modifications to established form-wound electrical insulation systems (EIS), such as changes in materials or processes. It is applied in the electrical engineering industry, particularly for large rotating machines like generators and motors, to ensure that modified insulation systems maintain their thermal class and reliability without requiring full requalification.
