EN 61858:2005

Electrical insulation systems - Thermal evaluation of modifications to an established wire-wound EIS

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 EN 60791 or has been evaluated by one of the procedures given in the EN 61857 series. This second edition cancels and replaces the first edition, published in 1999, and constitutes a technical revision that incorporates test procedures referenced in EN 60034-18-22.

Elektrische Isoliersysteme - Thermische Bewertung von Veränderungen an einem erprobten, drahtgewickelten EIS

Systèmes d'isolation électrique - Evaluation thermique des modifications apportées à un système d'isolation électrique éprouvé à enroulements à fil

Indique les procédures d'essai requises pour la qualification des modifications qui ont été apportées à un système d'isolation électrique éprouvé (SIE), pour ce qui concerne sa classification thermique. Cette norme s'applique aux systèmes d'isolation électrique existant dans les dispositifs électrotechniques à enroulements à fils. Les procédures d'essai se font par comparaison des performances d'un système d'isolation électrique candidat avec celles d'un système d'isolation électrique de référence dont l'expérience en service a été démontrée conformément à la EN 60791, ou qui a été évaluée par une des procédures décrites dans la série 61857.Cette deuxième édition annule et remplace la première édition, publiée en 1999, et constitue une révision technique qui inclut des procédures d'essai référencées dans la EN 60034-18-22.
