EN 61557-8:2007

Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. - Equipment for testing, measuring or monitoring of protective measures - Part 8: Insulation monitoring devices for IT systems

This part of IEC 61557 specifies the requirements for insulation monitoring devices (IMD) which permanently monitor the insulation resistance to earth of unearthed IT a.c. systems, for IT a.c. systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as of unearthed IT d.c. systems with voltages up to 1 500 V d.c. independent from the method of measuring. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. The following changes were made with respect to the previous edition: a) definitions complemented; b) revision of some requirements; c) addition of information on operating instructions; d) sections 'type tests' and 'routine tests' complemented; e) modification of Table 1; f) addition of Annexes A and B. The contents of the corrigendum of May 2007 have been included in this copy.

La présente partie de la CEI 61557 définit les exigences particulières applicables aux contrôleurs d'isolement (IMD) destinés à surveiller en permanence, et quelle que soit la méthode de mesure, la résistance d'isolement par rapport à la terre de réseaux IT c.a. non mis à la terre, ou de réseaux IT c.a. comprenant des circuits à courant continu reliés galvaniquement dont les tensions nominales sont au plus égales à 1 000 V c.a., et de réseaux IT c.c. dont les tensions nominales sont au plus égales à 1 500 V c.c. Cette deuxième édition annule et remplace la première édition publiée en 1997. Cette édition constitue une révision technique. Les principales modifications apportées par cette nouvelle édition sont les suivantes: a) la section sur les 'définitions' a été complétée; b) révision de certaines exigences; c) ajout d'informations relatives aux instructions de fonctionnement; d) les sections 'essais de type' et 'essais individuels de série ' ont été complétées; e) modification du Tableau 1; f) addition des Annexes A et B. Le contenu du corrigendum de mai 2007 a été pris en considération dans cet exemplaire.
