(Main)Live working - Conductive clothing for use at nominal voltage up to 800 kV a.c. and ± 600 kV d.c.
Live working - Conductive clothing for use at nominal voltage up to 800 kV a.c. and ± 600 kV d.c.
Applicable to conductive clothing, either assembled from component parts or forming a single complete clothing, worn by (electrically) skilled persons during live working (especially bare-hand working) at a nominal power system voltage up to 800 kV a.c. and ±600 kV d.c. It is applicable to conductive jackets, trousers, coveralls (one-piece clothing), gloves or mitts, hoods, shoes, overshoe socks and socks. The main changes with respect to the previous edition are listed below: - the scope has been extended to cover the use of conductive clothing to ±600 kV d.c.; - revision of the electrical resistance requirements of the fabrics used in conductive clothing; - revision of the testing procedures for complete clothing.
Arbeiten unter Spannung - Leitfähige Kleidung für die Verwendung bei Nenn-Wechselspannungen bis 800 kV und Gleichspannungen bis 600 kV
Travaux sous tension - Vêtements conducteurs pour usage jusqu'à 800 kV de tension nominale en courant alternatif et ± 600 kV en courant continu
Applicable aux vêtements conducteurs, qu'ils soient constitués de plusieurs éléments ou d'une seule pièce, portés par des personnes (électriquement) qualifiées lorsqu'elles travaillent sous tension (en particulier lors du travail au potentiel) pour des tensions nominales allant jusqu'à 800 kV en courant alternatif et à ±600 kV en courant continu. Elle est applicable aux vestons, pantalons, combinaisons (d'une seule pièce), aux gants ou moufles, aux cagoules, aux chaussures, aux couvre-chaussures (chausses) et aux chaussettes conducteurs. La plupart des changements respectants l'édition précédante sont listées ci-dessous: - le domaine d'application a été étendu pour s'appliquer aux vêtements conducteurs utilisés à ±600 kV en courant continu; - révision des exigences de résistance électrique des matériaux utilisés pour les vêtements conducteurs; - révision des procédures d'essai pour les vêtements complets
