Artificial pollution tests on high-voltage ceramic and glass insulators to be used on a.c. systems

IEC 60507:2013 is applicable for the determination of the power frequency withstand characteristics of ceramic and glass insulators to be used outdoors and exposed to polluted atmospheres, on a.c. systems with the highest voltage of the system greater than 1 000 V. These tests are not directly applicable to polymeric insulators, to greased insulators or to special types of insulators (insulators with semiconducting glaze or covered with any organic insulating material). The object of this International Standard is to prescribe procedures for artificial pollution tests applicable to insulators for overhead lines, substations and traction lines and to bushings. It may also be applied to hollow insulators with suitable precautions to avoid internal flashover. In applying these procedures to apparatus incorporating hollow insulators, the relevant technical committees should consider their effect on any internal equipment and the special precautions which may be necessary. This edition includes the following significant technical changes with respect to the previous edition: a) Corrections and the addition of explanatory material; b) The addition of Clause 4.3.2 on atmospheric correction; c) The change of the upper limit of conductivity of water to 0.1 S/m; and d) The extension to UHV voltages.

Essais sous pollution artificielle des isolateurs haute tension en céramique et en verre destinés aux réseaux à courant alternatif

L'IEC 60507:2013 est applicable à la détermination des caractéristiques de tenue à fréquence industrielle des isolateurs en céramique ou en verre qui sont à utiliser à l'extérieur et exposés à des atmosphères polluées, sur des réseaux à courant alternatif dont la tension la plus élevée du réseau est supérieure à 1 000 V. Ces essais ne sont pas directement applicables aux isolateurs polymériques, aux isolateurs graissés ou à des types particuliers d'isolateurs (revêtus d'un émail semi-conducteur ou couverts d'un matériau organique isolant). La présente Norme internationale a pour but de spécifier les exigences des procédures d'essais sous pollution artificielle applicables aux isolateurs pour lignes aériennes, pour postes et pour lignes de traction électrique, ainsi qu'aux traversées. Elle peut également s'appliquer aux isolateurs creux, avec des précautions appropriées afin d'éviter l'amorçage intérieur. Lors de l'application de ces procédures aux appareils dotés d'isolateurs creux, il convient que les comités d'études concernés tiennent compte de leur effet sur tout matériel interne et prennent les précautions particulières qui peuvent être nécessaires. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) Corrections et ajout d'éléments explicatifs; b) Ajout du paragraphe 4.3.2 relatif à la correction atmosphérique; c) La modification de la limite supérieure de la conductivité de l'eau à 0,1 S/m; d) Extension des tensions à la gamme ultra haute tension (UHV).

Preskusi z umetnim onesnaženjem visokonapetostnih keramičnih in steklenih izolatorjev, namenjenih za sisteme z izmenično napetostjo

Standard EN IEC 60507 se uporablja za ugotavljanje značilnosti obratovalnih frekvenc keramičnih in plinskih izolatorjev, ki se uporabljajo na prostem in so izpostavljeni onesnaženi atmosferi, namenjenih za sisteme z izmenično napetostjo, pri čemer je najvišja napetost sistema višja od 1000 V. Ti preskusi se ne uporabljajo neposredno za polimerne izolatorje, namaščene izolatorje ali posebne vrste izolatorjev (izolatorje, obdane s polprevodnim premazom ali poljubnim organskim izolacijskim materialom). Namen tega mednarodnega standarda je določiti postopke za preskuse umetnega onesnaževanja, ki se uporabljajo za izolatorje za nadzemne vode, razdelilne postaje in vlečne vode ter za skoznjike. Uporablja se lahko tudi za votle izolatorje, pri čemer so potrebni ustrezni previdnostni ukrepi, da se prepreči notranji preboj. Pri uporabi teh postopkov za aparate, ki zajemajo votle izolatorje, naj bi ustrezni tehnični odbori upoštevali njihov učinek na kakršno koli notranjo opremo in posebne previdnostne ukrepe, ki so morda potrebni.
