EN 60664-1:2007

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

Deals with insulation coordination for equipment within low-voltage systems. It applies to equipment for use up to 2 000 m above sea level having a rated voltage up to a.c. 1 000 V with rated frequencies up to 30 kHz, or a rated voltage up to d.c. 1 500 V. It specifies the requirements for clearances, creepage distances and solid insulation for equipment based upon their performance criteria. It includes methods of electric testing with respect to insulation coordination. The minimum clearances specified in this standard do not apply where ionized gases occur. Special requirements for such situations may be specified at the discretion of the relevant technical committee. This standard does not deal with distances - through liquid insulation, - through gases other than air, - through compressed air. Main changes have been made with respect to the previous edition: - Amendment of Japanese mains conditions with regard to the rated impulse voltages, the rationalized voltages and the nominal voltages of supply systems for different modes of overvoltage control - Amendment of dimensioning of clearances smaller than 0,01 mm - Alignment of the table and the corresponding formula regarding test voltages for verifying clearances at different altitudes - Amendment of interpolation of the creepage distance values for functional insulation - Amendment of creepage distance dimensioning taking into account ribs - Revision of the former Clause 4 'Tests and measurements' (now Clause 6) to achieve a more detailed description of the tests and their purpose, the test equipment and possible alternatives - Change of Annex C 'Partial discharge test methods' from a former technical report, Type 2 (now called TS), to a normative Annex C. Has the status of a basic safety publication in accordance with IEC Guide 104.

Isolationskoordination für elektrische Betriebsmittel in Niederspannungsanlagen - Teil 1: Grundsätze, Anforderungen und Prüfungen

Coordination de l'isolement des matériels dans les systèmes (réseaux) à basse tension - Partie 1: Principes, exigences et essais

Traite de la coordination de l'isolement des matériels dans les systèmes (réseaux) à basse tension. Elle s'applique au matériel utilisé jusqu'à 2 000 m au-dessus du niveau de la mer, ayant une tension assignée ne dépassant pas 1 000 V en courant alternatif, de fréquences assignées ne dépassant pas 30 kHz, ou une tension assignée ne dépassant pas 1 500 V en courant continu. Définit les exigences pour des distances d'isolement dans l'air, des lignes de fuite et l'isolation solide des matériels, à partir de leurs critères de performance. Elle comprend les méthodes d'essais diélectriques concernant la coordination de l'isolement. Les distances minimales d'isolement dans l'air spécifiées dans la présente norme 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. Ne traite pas des distances - à travers l'isolation liquide, - à travers les gaz autres que l'air, - à travers l'air comprimé. Les principales modifications suivantes ont été apportées à l'édition antérieure: - Modification des conditions du réseau électrique au Japon en ce qui concerne les tensions assignées de choc, les tensions rationalisées et les tensions nominales des réseaux d'alimentation pour différents modes de contrôle des surtensions - Modification du dimensionnement des distances d'isolement dans l'air inférieures à 0,01 mm - Alignement du tableau et des formules correspondantes concernant les tensions d'essai pour la vérification des distances d'isolement dans l'air à différentes altitudes - Modification de l'interpolation des valeurs de ligne de fuite pour l'isolation fonctionnelle - Modification du dimensionnement des lignes de fuite tenant compte des nervures - Révision de l'ancien Article 4 'Essais et mesures' (désormais Article 6) pour obtenir une description plus détaillée des essais et de leur objet, du matériel d'essai et des alternatives existantes - Transformation de l'Annexe C 'Méthodes d'essai de décharge partielle' d'un ancien rapport technique de type 2 (désigné désormais TS) en une Annexe C normative. A le statut de publication fondamentale de sécurité, conformément au Guide CEI 104.

− amendment of interpolation of the creepage distance values for functional insulation;
− amendment of creepage distance dimensioning taking into account ribs;
− revision of the former Clause 4 "Tests and measurements" (now Clause 6) to achieve a more detailed
description of the tests and their purpose, the test equipment and possible alternatives;
− change of Annex C "Partial discharge test methods" from a former technical report, Type 2 (now called
TS), to a normative Annex C.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-04-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-07-01
