Photovoltaic power systems - DC arc detection and interruption
IEC 63027:2023 applies to equipment used for the detection and optionally the interruption of electric DC arcs in photovoltaic (PV) system circuits. The document covers test procedures for the detection of series arcs within PV circuits, and the response times of equipment employed to interrupt the arcs. The document defines reference scenarios according to which the testing is conducted. This document covers equipment connected to systems not exceeding a maximum PV source circuit voltage of 1 500 V DC. This document provides requirements and testing procedures for arc-fault protection devices used in PV systems to reduce the risk of igniting an electrical fire.

Systèmes photovoltaïques - Détection et interruption d’arc en courant continu
IEC 63027:2023 s’applique aux équipements utilisés pour la détection et éventuellement pour l’interruption des arcs électriques en courant continu des circuits des systèmes photovoltaïques (PV). Il couvre les procédures d’essai de détection des arcs en série dans les circuits PV, et les temps de réponse de l'équipement utilisé pour interrompre les arcs. Le document définit les scénarios de référence selon lesquels les essais sont réalisés. Le présent document couvre les équipements reliés à des systèmes qui ne dépassent pas une tension maximale de circuit de source PV de 1 500 V en courant continu. Le présent document fournit des exigences et des procédures d’essai pour les dispositifs de protection contre les défauts d’arc utilisés dans les systèmes PV afin de réduire le risque d’incendie d’origine électrique.
Fotonapetostni sistemi - Zaznavanje enosmernega loka in prekinitve (IEC 63027:2023)
Standard IEC 63027:2023 se uporablja za opremo, ki se uporablja za zaznavanje in po izbiri prekinitev električnega enosmernega loka v tokokrogih fotonapetostnih sistemov (PV). Dokument obravnava preskusne postopke za zaznavanje niza lokov v tokokrogih fotonapetostnih sistemov in odzivne čase opreme, ki se uporablja za prekinitev lokov.
Dokument opredeljuje referenčne scenarije, po katerih se izvaja preskušanje. Ta dokument zajema opremo, priključeno na sisteme, ki ne presegajo največje napetosti izvornega tokokroga fotonapetostnih sistemov 1500 V enosmernega toka. Ta dokument podaja zahteve in preskusne postopke za zaščitne naprave za okvarni oblok, ki se uporabljajo v fotonapetostnih sistemih za zmanjšanje nevarnosti vžiga in električnega požara.
