(Main)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 15: Functional safety requirements for insulation monitoring devices in IT systems and equipment for insulation fault location in IT systems
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 15: Functional safety requirements for insulation monitoring devices in IT systems and equipment for insulation fault location in IT systems
IEC 61557-15:2014 specifies requirements related to functional safety and is based on the IEC 61508 standard series for the realization of Insulation Monitoring Devices (IMD) as specified in IEC 61557-8 and for Insulation Fault Location Systems (IFLS) according to IEC 61557-9, according to phase 10 of the IEC 61508-1 lifecycle. These devices provide safety related functions for IT systems. This part of IEC 61557 is - concerned only with functional safety requirements intended to reduce the functional risk during the use of IMDs and IFLSs; - restricted to risks arising directly from the device itself or from several IMDs or IFLSs working together in a system; and - intended to define the basic safety functions provided by the devices. This part of IEC 61557 does not - deal with electrical safety according to IEC 61010-1 and the requirements of IEC 61557-8 and IEC 61557-9; - cover the hazard and risk analysis of a particular use of the IMD or IFLS; - identify all the safety functions for the application in which the IMD or IFLS is used; and - cover the IMD or IFLS manufacturing process. This part of IEC 61557 is to be used in conjunction with Part 8 and Part 9. Functional safety requirements depend on the application and should be considered as part of the overall risk assessment of the specific application. The supplier of IMDs and IFLSs is not responsible for the application. The application designer is responsible for the risk assessment and for specifying the overall functional safety requirements of the complete IT system and he should select the functional safety level (SIL) of the IMD and/or IFLS when their safety function is part of the functional safety assessment in the IT system.
Elektrische Sicherheit in Niederspannungsnetzen bis AC 1 000 V und DC 1 500 V - Geräte zum Prüfen, Messen oder Überwachen von Schutzmaßnahmen - Teil 15: Anforderungen zur Funktionalen Sicherheit von Isolationsüberwachungsgeräten in IT-Systemen und von 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 15: Exigences de sécurité fonctionnelle pour les contrôleurs d'isolement de réseaux IT et les dispositifs de localisation de défauts d'isolement pour réseaux IT
L'IEC 61557-15:2014 spécifie les exigences relatives à la sécurité fonctionnelle; elle se fonde sur la série de normes CEI 61508 pour la réalisation de contrôleurs d'isolement (CPI) tels que spécifiés dans la CEI 61557-8 et de systèmes de localisation de défauts d'isolement (DLD) conformes à la CEI 61557-9 et à la phase 10 du cycle de vie de la CEI 61508-1. Ces dispositifs assurent des fonctions relatives à la sécurité pour des réseaux IT. La présente partie de la CEI 61557 - traite uniquement des exigences de sécurité fonctionnelle visant à réduire le risque fonctionnel lors de l'utilisation des CPI et des DLD; - se limite aux risques résultant directement du dispositif proprement dit ou de plusieurs dispositifs CPI ou DLD collaborant au sein d'un réseau donné; et - vise à définir les fonctions de sécurité de base assurées par les dispositifs. La présente partie de la CEI 61557 - ne traite pas de la sécurité électrique selon la CEI 61010-1 et des exigences des normes CEI 61557-8 et CEI 61557-9; - ne couvre pas l'analyse des dangers et des risques d'un usage particulier de l'CPI ou de l'DLD; - n'identifie pas toutes les fonctions de sécurité de l'application où l'CPI ou l'DLD est utilisé; et ne couvre pas le processus de fabrication de l'CPI ou de l'DLD. La présente partie de la CEI 61557 doit être utilisée conjointement aux Parties 8 et 9. Les exigences de sécurité fonctionnelle dépendent de l'application et il convient d'en tenir compte dans le cadre de l'appréciation globale du risque de l'application spécifique. Le fournisseur des CPI et des DLD n'est pas responsable de l'application qui en est faite. Le concepteur de l'application est responsable de l'appréciation du risque et il lui incombe de spécifier les exigences globales de sécurité fonctionnelle de l'ensemble du réseau IT et il convient qu'il sélectionne le niveau de sécurité fonctionnelle (SIL) de l'CPI et/ou de l'DLD lorsque leur fonction de sécurité fait partie de l'évaluation de la sécurité fonctionnelle du réseau IT.
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 - 15. del: Zahteve za funkcionalno varnost za naprave za nadzorovanje izolacije in opremo za ugotavljanje mesta izolacijske okvare v sistemih IT (IEC 61557-15:2014)
Standard EN IEC 61557-15 določa zahteve za funkcionalno varnost in temelji na skupini standardov IEC 61508 za realizacijo naprav za nadzorovanje izolacije (IMD), kot je opredeljeno v standardu IEC 61557-8, in za sisteme za ugotavljanje mesta izolacijske okvare (IFLS) v skladu s standardom IEC 61557-9, v skladu s fazo 10 življenjske dobe IEC 61508-1. Te naprave zagotavljajo z varnostjo povezane funkcije za sisteme IT: Ta del standarda IEC 61557: – obravnava le zahteve za funkcionalno varnost, namenjene zmanjšanju funkcionalnega tveganja med uporabo IMD in IFLS; – je omejen na tveganja, ki izhajajo neposredno iz same naprave ali iz več IMD ali IFLS, ki skupaj delujejo v sistemu; – je namenjen opredelitvi osnovnih varnostnih funkcij, ki jih zagotavljajo naprave. Ta del standarda IEC 61557 ne: – obravnava električne varnosti v skladu s standardom IEC 61010-1 ter zahtev standardov IEC 61557-8 in IEC 61557-9; – obravnava analize nevarnosti in tveganj posamezne uporabe IMD ali IFLS; – opredeljuje vseh varnostnih funkcij za uporabo, v kateri se uporabljata IMD ali IFLS; – obravnava proizvodnega procesa IMD ali IFLS. Zahteve za funkcionalno varnost so odvisne od uporabe in naj bi se štele za del splošne ocene tveganja za posamezno uporabo. Dobavitelj IMD ali IFLS ni odgovoren za uporabo. Snovalec uporabe je odgovoren za oceno tveganja in opredelitev splošnih zahtev za funkcionalno varnost celotnega sistema IT ter naj bi izbral raven funkcionalne varnosti (SIL) IMD in/ali IFLS, kadar je njuna varnostna funkcija del ocene funkcionalne varnosti sistema IT.
