Anotation

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. The contents of the corrigendum of August 2018 have been included in this copy. LIEC 60507:2013 est applicable a la determination des caracteristiques de tenue a frequence industrielle des isolateurs en ceramique ou en verre qui sont a utiliser a lexterieur et exposes a des atmospheres polluees, sur des reseaux a courant alternatif dont la tension la plus elevee du reseau est superieure a 1 000 V. Ces essais ne sont pas directement applicables aux isolateurs polymeriques, aux isolateurs graisses ou a des types particuliers disolateurs (revetus dun email semi-conducteur ou couverts dun materiau organique isolant). La presente Norme internationale a pour but de specifier les exigences des procedures dessais sous pollution artificielle applicables aux isolateurs pour lignes aeriennes, pour postes et pour lignes de traction electrique, ainsi quaux traversees. Elle peut egalement sappliquer aux isolateurs creux, avec des precautions appropriees afin deviter lamorcage interieur. Lors de lapplication de ces procedures aux appareils dotes disolateurs creux, il convient que les comites detudes concernes tiennent compte de leur effet sur tout materiel interne et prennent les precautions particulieres qui peuvent etre necessaires. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) Corrections et ajout delements explicatifs; b) Ajout du paragraphe 4.3.2 relatif a la correction atmospherique; c) La modification de la limite superieure de la conductivite de leau a 0,1 S/m; d) Extension des tensions a la gamme ultra haute tension (UHV). Le contenu du corrigendum daout 2018 a ete pris en consideration dans cet exemplaire.
