T/CEEIA 350-2019 Distributed Photovoltaic Generation System (DPVS) Direct Current Arc Fault Protection Technical Specification
Basic Information
Scope
Scope: This document specifies the technical requirements for the protection of series arc faults on the DC side of distributed photovoltaic power generation systems, including devices, methods, and testing. This document applies to series arc fault protection devices on the DC side of distributed photovoltaic power generation systems integrated with buildings (hereinafter referred to as "protection devices"). Other PV input systems may refer to this document for implementation. This document applies to higher-risk series arc faults. Since the photovoltaic power generation system protects against ground faults, ground faults occur first, thus reducing the risk of parallel arc faults.
