High-voltage switchgear and controlgear - Part 101: Synthetic testing
IEC 62271-101:2012 mainly applies to a.c. circuit-breakers within the scope of IEC 62271-100. It provides the general rules for testing a.c. circuit-breakers, for making and breaking capacities over the range of test duties described in 6.102 to 6.111 of IEC 62271-100:2008, by synthetic methods. This second edition cancels and replaces the first edition published in 2007 and its Amendment 1 published in 2011. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the first edition: - addition of the new rated voltages of 1 100 kV and 1 200 kV; - revision of Annex F regarding circuit-breakers with opening resistors; - alignment with the second edition of IEC 62271-100:2008 and its Amendment 1 (2012). This publication is to be read in conjunction with IEC 62271-100:2008.

Appareillage à haute tension - Partie 101: Essais synthétiques
La CEI 62271-101:2012 s'applique principalement aux disjoncteurs à courant alternatif définis dans le domaine d'application de la CEI 62271-100. Elle donne les règles générales d'essais de ces disjoncteurs, pour les pouvoirs de fermeture et de coupure dans la gamme des séquences d'essais décrites de 6.102 à 6.111 de la CEI 62271-100:2008, à l'aide de méthodes d'essais synthétiques. Cette deuxième édition annule et remplace la première édition parue en 2007 et l'Amendement 1 paru en 2011. Elle constitue une révision technique. Les principales modifications par rapport à la précédente édition sont les suivantes: - ajout des nouvelles tensions assignées 1 100 kV et 1 200 kV; - révision de l'Annexe F qui traite des disjoncteurs équipés de résistances d'ouverture; - alignement avec la deuxième édition de la CEI 62271-100:2008 et Amendement 1 (2012). Cette publication doit être lue conjointement avec la CEI 62271-100:2008.
Visokonapetostne stikalne in krmilne naprave - 101. del: Sintetično preskušanje (IEC 62271-101:2012)
Ta del standarda IEC 62271 se uporablja predvsem za izmenične odklopnike v okviru standarda IEC 62271-100. Zagotavlja splošna pravila za preskušanje izmeničnih odklopnikov, ustvarjanje in prekinjanje kapacitet v okviru preskusnih obremenitev, opisanih v točkah od 6.102 do 6.111 standarda IEC 62271-100:2008, s sintetičnimi metodami. Sintetično preskušanje je dokazano stroškovno učinkovit in tehnično ustrezen način za preskušanje visokonapetostnih izmeničnih odklopnikov v skladu z zahtevami standarda IEC 62271-100 ter je enakovredno neposrednemu preskušanju. Opisane metode in tehnike se splošno uporabljajo. Namen tega standarda je določiti merila za sintetično preskušanje in ustrezno vrednotenje rezultatov. Taka merila bodo zagotovila veljavnost preskusne metode brez omejevanja inovacij v zvezi s preskusnimi tokokrogi.
