EN 61557-7:2007

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 7: Phase sequence

This part of IEC 61557 specifies the requirements for measuring equipment applied to testing the phase sequence in three-phase distribution systems. Indication of the phase sequence may be mechanical, visual and/or audible. This part of IEC 61557 does not apply to ancillary measuring equipment for other quantities, for example voltage testers comprising an additional phase sequence indicator. It does not apply to monitoring relays. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a minor revision.

Elektrische Sicherheit in Niederspannungsnetzen bis AC 1 000 V und DC 1 500 V - Geräte zum Prüfen, Messen oder Überwachen von Schutzmaßnahmen - Teil 7: Drehfeld

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 7: Ordre de phases

La présente partie de la CEI 61557 définit les exigences applicables aux appareils de mesure destinés à contrôler l'ordre des phases dans des réseaux de distribution triphasés. Le dispositif d´affichage de l'ordre des phases peut être mécanique, optique et/ou acoustique. La présente partie de la CEI 61557 ne couvre pas les dispositifs supplémentaires de mesure, par exemple des indicateurs de tension destinés à mesurer d´autres grandeurs. Elle ne s'applique pas aux relais de surveillance. Cette deuxième édition annule et remplace la première édition publiée en 1997. Cette édition constitue une révision mineure.

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 - 7. del: Fazno zaporedje (IEC 61557-7:2007)

Ta del IEC 61557 poudarja zahteve za merjenje opreme, ki se nanašajo na preskušanje faznega zaporedja v trifaznem distribucijskem sistemu. Indikacija faznega zaporedja je lahko mehanska, vidna in/ali slišna.
