Anotation

IEC 60947-9-2:2021 covers internal arc-fault control devices, hereinafter referred to as IACD, which are intended to: – detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by processing (at a minimum) the optical effect of an internal arc-fault, and – operate mitigation device (either external or combined) in order to minimize the effects of the internal arc-fault. LIEC 60947-9-2:2021 s’applique aux dispositifs de controle de defaut d’arc interne, ci-apres designes IACD, qui sont destines a: – detecter les defauts d’arc interne dans les ensembles d’appareillage a basse tension, en traitant (a minima) le phenomene optique d’un defaut d’arc interne, et – faire fonctionner un dispositif de limitation (externe ou combine) afin de reduire le plus possible les effets de defaut d’arc interne
