EN 61557-13:2011

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 13: Hand-held and hand-manipulated current clamps and sensors for measurement of leakage currents in electrical distribution systems

IEC 61557-13:2011 defines special performance requirements for hand-held and hand-manipulated current clamps and sensors for measurement of leakage currents in electrical distribution systems up to 1 000 V a.c. and 1 500 V d.c., taking into account the influence of high external low-frequency magnetic fields and other influencing quantities. This standard does not apply to current clamps or sensors which are used in combination with devices for insulation fault location according to IEC 61557-9, unless it is specified by the manufacturer.

Elektrische Sicherheit in Niederspannungsnetzen bis AC 1 000 V und DC 1 500 V – Geräte zum Prüfen, Messen oder Überwachen von Schutzmaßnahmen – Teil 13: Handgehaltene und handbediente Strommesszangen und Stromsonden zur Messung von Ableitströmen in elektrischen Anlagen

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 13: Pinces et capteurs de courant portatifs et manipulés à la main pour la mesure des courants de fuite dans les réseaux de distribution électriques

La CEI 61557-13:2011 définit les exigences spécifiques d'aptitude à la fonction relatives aux pinces et capteurs de courant portatifs et manipulés à la main, en vue de la mesure des courants de fuite dans les réseaux de distribution électriques de 1 000 V en courant alternatif et 1 500 V en courant continu, en tenant compte de l'influence des champs magnétiques à basse fréquence externes élevés et autres grandeurs d'influence. La présente norme ne s'applique pas aux pinces et capteurs de courant utilisés en association avec des dispositifs prévus pour la localisation des défauts d'isolement conformes à la CEI 61557-9, sauf spécification de la part du fabricant.

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 - 13. del: Ročne in ročno upravljane tokovne klešče in senzorji za merjenje uhajavih tokov v električnih razdelilnih sistemih (IEC 61557-13:2011)

Ta del IEC 61557 določa posebne delovne zahteve za ročne in ročno upravljane tokovne klešče in senzorje za merjenje uhajavih tokov v električnih razdelilnih sistemih, ki ne presegajo 1000 V izmeničnega toka in 1500 V enosmernega toka, upoštevajoč vpliv visokih zunanjih nizkofrekvenčnih magnetnih polj in drugih vplivajočih količin. Ta standard ne velja za tokovne klešče ali senzorje, ki se uporabljajo skupaj z napravami za lociranje napak v izolaciji, ki so v skladu z IEC 61557-9, razen če tako navaja proizvajalec.
