T/CEEIA 468-2020 The test method for the action characteristics of a fault arc detection module used in a DC system

Scope

Scope: This document specifies the general requirements for conducting operational characteristics verification tests on fault arc detection modules (hereinafter referred to as "DC-AFDU") intended for use in DC systems with a rated voltage not exceeding 1,000 V DC and a rated current not exceeding 63 A. The DC-AFDU specified in this document refers to: - a single device with disconnection capability that can detect a fault arc under specified conditions and promptly disconnect the protected circuit; or - a single device that cooperates with a circuit breaker to protect the circuit. This document also applies to the operational characteristics verification tests of other detection modules or devices with multiple functions (including at least the fault arc detection function) related to DC fault arc operation.
