Annotation of standard text IEC 63027-ed.1.0 :
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. IEC 63027:2023 s’applique aux equipements utilises pour la detection et eventuellement pour l’interruption des arcs electriques en courant continu des circuits des systemes photovoltaiques (PV). Il couvre les procedures d’essai de detection des arcs en serie dans les circuits PV, et les temps de reponse de lequipement utilise pour interrompre les arcs. Le document definit les scenarios de reference selon lesquels les essais sont realises. Le present document couvre les equipements relies a des systemes qui ne depassent pas une tension maximale de circuit de source PV de 1 500 V en courant continu. Le present document fournit des exigences et des procedures d’essai pour les dispositifs de protection contre les defauts d’arc utilises dans les systemes PV afin de reduire le risque d’incendie d’origine electrique.
