Annotation of standard text IEC/TR 60664-2-1-ed.2.0 :
IEC/TR 60664-2-1:2011, which is a technical report, serves as an application guide for technical committees and manufacturers specifying dimensioning requirements for products in accordance with the IEC 60664 series. The significant items for consideration are as follows: a) nominal system voltage(s) or rated insulation voltage(s); b) overvoltage category of the products (OV cat.); c) any type of overvoltages; d) frequency of the voltage; e) characteristics of the solid insulating material; f) pollution degree and humidity levels. The main changes with respect to the previous edition are listed below: - the previous edition was only an application guide for IEC 60664-1. This second edition takes into account not only IEC 60664-1 but also the other parts IEC 60664-3, IEC 60664-4, and IEC 60664-5 and their interrelation; - principles of the IEC 60664 series for insulation dimensioning of LV equipment are explained and examples of practical application are provided together with some background information; - Annex A provides an overview of clauses of IEC 60664-1 requiring decisions by technical committees, or specification of options, or requiring activities of the manufacturer; - Annex B provides an overview of such clauses of IEC 60664-4; - Annex C provides an overview of such clauses of IEC 60664-5; - Annex D amends the tables of Annex F of IEC 60664-1:2007 with rated impulse voltages for voltages line to neutral derived from nominal d.c. voltages up to and including 1 500 V. The contents of the corrigendum of October 2011 have been included in this copy. La CEI/TR 60664-2-1:2011 qui est un rapport technique, sert comme guide dapplication aux comites detudes et aux fabricants en specifiant les exigences en matiere de dimensionnement des produits conformes a la serie CEI 60664. Les elements significatifs a prendre en compte sont les suivants: a) la/les tension(s) nominale(s) du reseau ou la/les tension(s) assignee(s) disolement; b) la categorie de surtension des produits (cat. OV); c) tous les types de surtension; d) la frequence de la tension; e) les caracteristiques du materiau isolant solide; f) le degre de pollution et les niveaux dhumidite. Les modifications principles par rapport a ledition precedente sont les suivantes: - ledition precedente netait quun guide dapplication pour la CEI 60664-1. Cette deuxieme edition prend en compte non seulement la CEI 60664-1 mais egalement les autres parties qui sont les CEI 60664-3, CEI 60664-4, et CEI 60664-5 et leurs relations mutuelles; - les principes de la serie 60664 concernant le dimensionnement de lisolement des appareils basse tension sont expliques et des exemples dapplication pratiques sont fournis avec des informations de base; - lAnnexe A fournit une vue densemble des articles de la CEI 60664-1 necessitant des decisions des comites techniques, ou des specifications des options, ou necessitant les activites du fabricant; - lAnnexe B fournit une vue densemble de tels articles de la CEI 60664-4; - lAnnexe C fournit une vue densemble de tels articles de la CEI 60664-5; - lAnnexe D amende les tableaux de lAnnexe F de la CEI 60664-1:2007 avec des tensions dimpulsion assignees concernant les tensions phase-neutre derivees des tensions nominales en courant continu allant jusqua 1 500 V inclus. Le contenu du corrigendum doctobre 2011 a ete pris en consideration dans cet exemplaire.
