Scope

Scope: This document specifies the terms, definitions, classification, characteristics, marking, standard working conditions, structure, operation requirements, and testing of arc fault detectors (PV-AFD) for low-voltage photovoltaic (PV) systems. The PV-AFD specified in this document is applicable to the detection of DC arc faults in PV systems with a maximum open-circuit voltage not exceeding 1500 V DC. Note 1: According to GB/T 16895.32, the PV-AFD specified in this document is used for monitoring series arc faults caused by insulation failures in PV systems, and issues a signal output when a sustained arc in the PV system is sufficient to ignite other flammable materials. Note 2: The PV-AFD specified in this document can be installed as a standalone device in PV junction boxes or as an electrical accessory in PV inverters and other equipment for arc fault monitoring in PV systems.
