Insulation coordination for equipment within low-voltage systems - Part 4: Consideration of high-frequency voltage stress

Deals with basic, supplementary and reinforced insulation subjected to high-frequency voltage stress within low-voltage equipment. The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to Part 1. It is applicable for the dimensioning of clearances, creepage distances and solid insulation stressed by any type of periodic voltages with a fundamental frequency above 30 kHz and up to 10 MHz. This part of EN 60664 can only be used together with EN 60664-1 or with EN 60664-5 (in this standard called Part 1 or Part 5). By using Part 1 or Part 5 together with this part the frequency limit of Part 1 or Part 5 is extended to frequencies higher than 30 kHz. This part also applies to Part 3 for frequencies greater than 30 kHz and protection of type 1. For type 2 protection this question is under consideration. Applies to equipment for use up to 2 000 m above sea level having a rated voltage up to a.c. 1 000 V. Specifies the requirements for clearances, creepage distances and solid insulation for equipment based upon their performance criteria. lt includes methods of electric testing with respect to insulation coordination. The minimum clearances specified in this part do not apply where ionized gases occur. Special requirements for such situations may be specified at the discretion of the relevant technical committee. This part does not deal with distances - through liquid insulation, - through gases other than air, - through compressed air. The object of this standard is to guide technical committees responsible for different equipment in order to rationalise their requirements so that insulation coordination is achieved when specifying clearances in air, creepage distances and solid insulation for equipment. The major changes made during the revision of EN 60664-4 were the following: - inclusion of more recent information about the withstand characteristics of insulation at high-frequency voltage stress

Isolationskoordination für elektrische Betriebsmittel in Niederspannungsanlagen - Teil 4: Berücksichtigung von hochfrequenten Spannungsbeanspruchungen

Coordination de l'isolement des matériels dans les systèmes (réseaux) à basse tension - Partie 4: Considérations sur les contraintes de tension à haute fréquence

Traite de l'isolation principale, de l'isolation supplémentaire et de l'isolation renforcée soumises à des contraintes de tension à haute fréquence dans les matériels à basse tension. Les valeurs de dimensionnement s'appliquent directement à l'isolation principale; pour l'isolation renforcée, des exigences supplémentaires s'appliquent, conformément à la Partie 1. Elle est applicable pour le dimensionnement des distances d'isolement, des lignes de fuite et de l'isolation solide subissant des contraintes par tout type de tensions périodiques avec une fréquence fondamentale supérieure à 30 kHz et pouvant atteindre 10 MHz. La présente partie de la EN 60664 ne peut être utilisée que conjointement à la EN 60664-1 ou à la EN 60664-5 (intitulées Partie 1 ou Partie 5 dans la présente norme). En utilisant la Partie 1 ou la Partie 5 conjointement à la présente partie, la limite de fréquence de la Partie 1 ou de la Partie 5 est étendue à des fréquences supérieures à 30 kHz. La présente partie s'applique également à la Partie 3 pour les fréquences supérieures à 30 kHz et la protection de type 1. Pour la protection de type 2, cette question est à l'étude. S'applique aux matériels utilisés 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. Définit les exigences pour des distances d'isolement, des lignes de fuite et de l'isolation solide des matériels, basées sur leurs critères de performance. Elle comprend les méthodes d'essais diélectriques en tenant compte de la coordination de l'isolement. Les distances d'isolement minimales spécifiées dans la présente partie ne s'appliquent pas en présence de gaz ionisés. Les exigences particulières dans de telles conditions peuvent être spécifiées par les comités d'études appropriés, comme ils l'entendent. La présente partie ne traite pas des distances - à travers l'isolation liquide, - à travers les gaz autres que l'air, - à travers l'air comprimé. L'objet de la présente
