Electrical insulation systems – Thermal evaluation of modifications to an established wire-wound EIS
|Publication Date:||1 July 2008|
|ICS Code (Insulation systems):||29.080.30|
This International Standard 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 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 with IEC 60505 or has been evaluated by one of the procedures given in the IEC 61857 series.
