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 2: Insulation resistance

This part of IEC 61557 specifies the requirements applicable to equipment for measuring the insulation resistance of equipment and installations in the de-energized state. 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 have been revised; c) addition of a warning pictogram; d) complete revision of the subclause on overload tests.

Elektrische Sicherheit in Niederspannungsnetzen bis AC 1 000 V und DC 1 500 V - Geräte zum Prüfen, Messen oder Überwachen von Schutzmaßnahmen - Teil 2: Isolationswiderstand

Sécurité électrique dans les réseaux de distribution basse tension de 1 000 V c.a. et 1 500 V. c.c. - Dispositifs de contrôle, de mesure ou de surveillance de mesures de protection - Partie 2: Résistance d'isolement

La présente partie de la CEI 61557 définit les exigences applicables aux appareils destinés à mesurer la résistance d'isolement d´appareils et d´installations hors tension. 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) révision des définitions; b) révision de certaines exigences; c) ajout d'un pictogramme d'avertissement; d) le paragraphe consacré aux essais de surcharge' a été entièrement révisée.

Električna varnost v nizkonapetostnih razdelilnih sistemih izmenične napetosti do 1 kV in enosmerne napetosti do 1,5 kV - Oprema za preskušanje, merjenje ali nadzorovanje zaščitnih ukrepov - 2. del: Izolacijska upornost (IEC 61557-2:2007)

Ta del IEC 61557 poudarja zahteve, uporabne za opremo (merilnike) za merjenje izolacijske upornosti opreme in inštalacij v breznapetostnem stanju.
