Electrical insulation systems. Thermal evaluation of modifications to an established electrical insulation system (EIS) - Wire-wound winding EIS Ingestion-build-224916 Unused natural esters as delivered1 Scope This part of IEC 61858 lists the required test procedures for qualification of modifications of an established electrical insulation system (EIS) with respect to its thermal classification. This standard is applicable to EIS used in wire wound winding electrotechnical devices. The test procedures are comparative in that the performance of a candidate EIS is compared to that of a reference EIS, which has proven service experience in accordance
