EN 61557-9:2015

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 9: Equipment for insulation fault location in IT systems

IEC 61557-9:2014 specifies the requirements for the insulation fault location system (IFLS) which localizes insulation faults in any part of the system in unearthed IT a.c. systems and unearthed IT a.c. systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as in unearthed IT d.c. systems with voltages up to 1 500 V d.c., independent of the measuring principle. IT systems are described in IEC 60364-4-41 amongst other literature. Additional data for a selection of devices in other standards should be noted. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision which includes the following significant technical changes with respect to the previous edition: - the scope, normative references, terms and definitions have been complemented; - abbreviations are listed and explained; - requirements, marking and operating instructions have been revised; - mandatory and optional functions have been defined and their terminology has been adapted to IEC 61557-15; - mechanical requirements have been added; - Clause 6 "Tests" has been revised; and - new Tables have been added.

Elektrische Sicherheit in Niederspannungsnetzen bis AC 1 000 V und DC 1 500 V – Geräte zum Prüfen, Messen oder Überwachen von Schutzmaßnahmen – Teil 9: Einrichtungen zur Isolationsfehlersuche in IT-Systemen

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 9: Dispositifs de localisation de défauts d'isolement pour réseaux IT

L'IEC 61557-9:2014 spécifie les exigences applicables aux dispositifs de localisation de défauts d'isolement (DLD) qui, indépendamment du principe de mesure, peuvent localiser les défauts d'isolement des parties de réseaux IT à courant alternatif non mis à la terre et des réseaux IT à courant alternatif non mis à la terre comprenant des circuits à courant continu reliés galvaniquement dont les tensions nominales sont au plus égales à 1 000 V en courant alternatif, et de réseaux IT à courant continu non mis à la terre dont les tensions sont au plus égales à 1 500 V en courant continu. Les réseaux IT sont décrits entre autres dans l'IEC 60364-4-41. Il convient de noter que, pour le choix des appareils, des indications supplémentaires sont données dans d'autres normes. Cette troisième édition annule et remplace la deuxième édition parue en 2009. Elle constitue une révision technique qui inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - le domaine d'application, les références normatives, les termes et définitions ont été complétés; - énumération et explication des abréviations; - les exigences de marquage, les instructions de fonctionnement ont été révisées; - définition des fonctions obligatoires et facultatives et adaptation de leur terminologie à l'IEC 61557-15; - ajout d'exigences mécaniques; - l'Article 6 "Essais" a été révisé; - et des nouveaux Tableaux ont été ajoutés.

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 - 9. del: Oprema za ugotavljanje mesta izolacijske okvare v IT-sistemih (IEC 61557-9:2014)

Ta del standarda IEC 61557 določa zahteve za sistem za ugotavljanje mesta izolacijske okvare (IFLS), ki ugotovi mesto izolacijskih okvar v katerem koli delu sistema pri neozemljenih IT sistemih na izmenični tok, neozemljenih IT-sistemih na izmenični tok z galvansko povezanimi tokokrogi enosmernega toka z nominalnimi vrednostmi izmenične napetosti do 1000 V ter neozemljenih IT-sistemih na enosmerni tok z vrednostmi enosmerne napetosti do 1500 V, neodvisno od principa merjenja.
IT-sistemi so med drugim opisani tudi v standardu IEC 60364-4-41. Upoštevali naj bi dodatne podatke za izbiro naprav v drugih standardih.
OPOMBA: več informacij o ugotavljanju mesta izolacijske okvare je mogoče najti v teh standardih: IEC 60364-4-41:2005, 411.6 in IEC 60364-5-53:2001, 531.3.
