EN 61557-3:2007

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 3: Loop impedance

This part of IEC 61557 specifies the requirements applicable to equipment for measuring the loop impedance between a phase conductor and the protective conductor or between a phase conductor and neutral or between two phase conductors by using the voltage drop when the circuit under test is loaded. 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) addition of new influence quantities E9 and E10.

Elektrische Sicherheit in Niederspannungsnetzen bis AC 1 000 V und DC 1 500 V - Geräte zum Prüfen, Messen oder Überwachen von Schutzmaßnahmen - Teil 3: Schleifenwiderstand

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 3: Impédance de boucle

La présente partie de la CEI 61557 définit les exigences applicables aux appareils destinés à mesurer l'impédance de boucle entre un conducteur de phase et le conducteur de protection ou entre le conducteur de phase et le conducteur neutre ou entre deux conducteurs de phase en utilisant la chute de tension lorsque le circuit à tester est chargé. 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) Des informations relatives aux instructions de fonctionnement ont été ajoutées; d) De nouvelles grandeurs d'influence E9 et E10 ont été ajoutées.

Električna varnost v nizkonapetostnih razdelilnih sistemih za izmenične napetosti do 1 kV in enosmerne napetosti do 1,5 kV - Oprema za preskušanje, merjenje ali nadzorovanje zaščitnih ukrepov - 3. del: Impedanca zanke (IEC 61557-3:2007)

Ta del IEC 61557 poudarja zahteve, primerne za opremo za merjenje impedance (upornosti) zanke med linijskim in zaščitnim vodnikom, linijskim in nevtralnim vodnikom ali med dvema linijskima vodnikoma  z uporabo padca napetosti, ko je tokokrog obremenjen med preskušanjem.
