Annotation of standard text IEC 61643-22-ed.2.0 :
IEC 61643-22:2015 describes the principles for the selection, operation, location and coordination of SPDs connected to telecommunication and signalling networks with nominal system voltages up to 1 000 V r.m.s. a.c. and 1 500 V d.c. This standard also addresses SPDs that incorporate protection for signalling lines and power lines in the same enclosure (so called multiservice SPDs). This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Update the use of multiservice SPDs (Article 8); - Comparison between SPD classification of IEC 61643-11 and IEC 61643-21 (7.3.3); - Consideration of new transmission systems as PoE (Annex F); - EMC requirements of SPDs (Annex G); - Maintenance cycles of SPDs (Annex I). Keywords: SPD, surge protective devices LIEC 61643-22:2015 decrit les principes a utiliser pour le choix, le fonctionnement, la localisation et la coordination des parafoudres connectes aux reseaux de telecommunications et de transmission de signaux sous une tension nominale de reseau jusqua 1 000 V en valeur efficace en courant alternatif et 1 500 V en courant continu. La presente norme couvre aussi les parafoudres qui incorporent la protection pour les lignes de transmission de signaux et les lignes de puissance dans la meme enveloppe (parafoudres dits parafoudres multifonctions. Cette deuxieme edition annule et remplace la premiere edition parue en 2004. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - Mise a jour de lutilisation des parafoudres multifonction (Article 8); - Comparaison entre les classifications de parafoudres de lIEC 61643-11 et de lIEC 61643-21 (7.3.3); - Prise en compte des nouveaux systemes de transmission PoE (Annexe F); - Exigences de CEM des parafoudres (Annexe G); - Cycles de maintenance des parafoudres (Annexe I).
