Annotation of standard text IEC 60137-ed.7.0 :
IEC 60137:2017 is now available as IEC 60137:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60137:2017 specifies the characteristics and tests for insulated bushings. This standard is applicable to bushings, as defined in Clause 3, intended for use in electrical apparatus, machinery, transformers, switchgear and installations for three-phase alternating current systems, having highest voltage for equipment above 1 000 V and power frequencies of 15 Hz up to and including 60 Hz. Subject to special agreement between purchaser and supplier, this standard may be applied, in part or as a whole, to the following: - bushings used in other than three-phase systems; - bushings for high-voltage direct current systems; - bushings for testing transformers; - bushings for capacitors. Special requirements and tests for transformer bushings in this standard apply also to reactor bushings. This standard is applicable to bushings made and sold separately. Bushings which are a part of an apparatus and which cannot be tested according to this standard should be tested with the apparatus of which they form part. This edition includes the following significant technical changes with respect to the previous edition: - Resin-impregnated synthetic (RIS) bushings has been introduced. - Bushings with Um 72,5 kV. - The altitude correction procedure has been revised ( > 1 000 m). - An explanation about Very Fast Transient (VFT) phenomenon and its impact on bushings has been included. The contents of the corrigendum of May 2018 have been included in this copy. IEC 60137:2017 est disponible sous forme de IEC 60137:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente. LIEC 60137:2017 specifie les caracteristiques et les essais applicables aux traversees isolees. La presente norme sapplique aux traversees, telles quelles sont definies a l’Article 3, destinees a etre utilisees dans les dispositifs electriques, les machines, les transformateurs, les appareillages de connexion et les installations pour des systemes a courant alternatif triphase possedant une tension plus elevee pour le materiel depassant 1 000 V et des frequences industrielles comprises entre 15 Hz et 60 Hz (inclus). Sous reserve d’un accord specifique entre l’acheteur et le fournisseur, cette norme peut etre appliquee, en partie ou en totalite, aux elements suivants: - traversees utilisees dans d’autres systemes que ceux a courant alternatif triphase; - traversees pour les systemes a courant continu haute tension; - traversees pour les transformateurs d’essai; - traversees pour les condensateurs. Les exigences speciales et les essais concernant les traversees de transformateurs specifiees dans la presente norme s’appliquent egalement aux traversees pour bobines dinductance. La presente norme sapplique aux traversees fabriquees et commercialisees separement. Il convient que les traversees qui font partie integrante dun appareillage, et qui ne peuvent etre soumises a lessai selon la presente norme, soient soumises a lessai avec lappareillage dont elles font partie. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: - Ajout de traversees en matiere synthetique impregnee de resine (RIS – resin-impregnated synthetics). - Ajout de traversees dont Um 72,5 kV. - La procedure de correction d’altitude a ete revisee ( > 1 000 m). - Ajout d’une explication sur le phenomene des transitoires tres rapides (VFT – Very Fast transient) et sur leur impact sur les traversees. Le contenu du corrigendum de mai 2018 a ete pris en consideration dans cet exemplaire.
