Insulation coordination for equipment within low-voltage supply systems - Part 1: Principles, requirements and tests

IEC 60664-1:2020 deals with insulation coordination for equipment having a rated voltage up to AC 1 000 V or DC 1 500 V connected to low-voltage supply systems. This document applies to frequencies up to 30 kHz. It applies to equipment for use up to 2 000 m above sea level and provides guidance for use at higher altitudes. It provides requirements for technical committees to determine clearances, creepage distances and criteria for solid insulation. It includes methods of electrical testing with respect to insulation coordination. The minimum clearances specified in this document do not apply where ionized gases are present. Special requirements for such situations can be specified at the discretion of the relevant technical committee. This document does not deal with distances: – through liquid insulation; – through gases other than air; – through compressed air. This edition includes the following significant technical changes with respect to the previous edition:
update of the Scope, Clauses 2 and 3,
addition of 1 500 V DC into tables,
new structure for Clauses 4 and 5,
addition of Annex G with a flowchart for clearances,
addition of Annex H with a flowchart for creepage distances,
update of distances altitude correction in a new Table F.10.  It has the status of a basic safety publication in accordance with IEC Guide 104.

Isolationskoordination für Betriebsmittel in Niederspannungs-Stromversorgungssystemen - Teil 1: Grundsätze, Anforderungen und Prüfungen

Coordination de l'isolement des matériels dans les réseaux d'énergie électrique à basse tension - Partie 1: Principes, exigences et essais

L’IEC 60664-1:2020 traite de la coordination de l'isolement des matériels ayant une tension assignée allant jusqu’à 1 000 V en courant alternatif ou jusqu’à 1 500 V en courant continu connectés aux réseaux d’énergie électrique à basse tension. Le présent document s’applique aux fréquences jusqu’à 30 kHz inclus. NOTE 1 Les exigences de coordination de l’isolement des matériels dans les réseaux d’énergie électrique à basse tension dont les fréquences assignées sont supérieures à 30 kHz sont données dans l’IEC 60664-4. NOTE 2 Des tensions plus élevées peuvent exister dans les circuits internes des matériels. Il s'applique au matériel utilisé jusqu'à 2 000 m au-dessus du niveau de la mer, et fournit des recommandations pour l’utilisation à des altitudes plus élevées (Voir  REF _Ref452123764 \r \h \* MERGEFORMAT 5.2.3.4 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E0000005F005200650066003400350032003100320033003700360034000000 ). Il définit les exigences permettant aux comités d’études de déterminer les distances d'isolement, les lignes de fuite et les critères pour l’isolation solide. Il comprend les méthodes d'essais diélectriques concernant la coordination de l'isolement. Les distances d'isolement minimales spécifiées dans le présent document ne s'appliquent pas en présence de gaz ionisés. Les exigences particulières dans de telles conditions peuvent être spécifiées, comme ils l'entendent, par les comités d'études compétents. Le présent document ne traite pas des distances: – à travers l'isolation liquide; – à travers les gaz autres que l'air; – à travers l'air comprimé. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
mise à jour du Domaine d’application et des Articles 2 et 3,
nouvelle structure pour les Articles 4 et 5,
ajout de 1 500 V en courant continu dans les tableaux dans Annexe B et F,
mise à jour de la correction de l’altitude des distances dans un nouveau Tableau F.10,
ajout d’une Annexe G avec un organigramme relatif aux distances d’isolement,
ajout d’une Annexe H avec un organigramme relatif aux lignes de fuite.  Elle a le statut d’une publication fondamentale de sécurité conformément au Guide 104 de l’IEC.
