IEC 63027:2023 pdf download,Photovoltaic power systems – DC arc detection and interruption.
EC 63027:2023 applies to equipment used for the detection and optionally the interruption of electric DC arcs in photovoltaic (PV) system circuits.
EC 63027:2023 covers test procedures for the detection of series arcs within PV circuits, and the response times of equipment employed to interrupt the arcs.
EC 63027:2023 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.
