Insulation co-ordination - Part 2: Application guidelines
NEW!IEC 60071-2:2018 is available as IEC 60071-2:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60071-2:2018 constitutes application guidelines and deals with the selection of insulation levels of equipment or installations for three-phase electrical systems. It gives guidance for the determination of the rated withstand voltages for ranges I and II of IEC 60071-1 and to justify the association of these rated values with the standardized highest voltages for equipment. It covers three-phase systems with nominal voltages above 1 kV. It has the status of a horizontal standard in accordance with IEC Guide 108. This edition includes the following significant technical changes with respect to the previous edition: a) the annex on clearance in air to assure a specified impulse withstand voltage installation is deleted because the annex in IEC 60071-1 is overlapped; b) 4.2 and 4.3 on surge arresters are updated; c) 4.3.5 on very-fast-front overvoltages is revised. Annex J on insulation co-ordination for very-fast-front overvoltages in UHV substations is added; d) Annex H on atmospheric correction – altitude correction is added. e) Annex I on evaluation method of non-standard lightning overvoltage shape is added.

Coordination de l'isolement - Partie 2: Lignes directrices en matière d'application
NEW!IEC 60071-2:2018 est disponible sous forme de IEC 60071-2:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60071-2:2018 constitue des lignes directrices en matière d'application et concerne le choix des niveaux d'isolement des matériels ou des installations pour les réseaux triphasés. Elle a pour objet de donner des recommandations pour la détermination des tensions de tenue assignées pour les plages I et II de l'IEC 60071-1 et de justifier l'association de ces valeurs assignées avec les valeurs normalisées des tensions les plus élevées pour le matériel. Il traite des réseaux triphasés de tension nominale supérieure à 1 kV. Il a le statut d'une norme horizontale conformément au Guide 108 de l'IEC. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) l'annexe relative à la distance d'isolement dans l'air pour installation garantissant une tension de tenue aux chocs spécifiée est supprimée car cette annexe est déjà présente dans l'IEC 60071-1; b) 4.2et 4.3relatifs aux parafoudres ont été mis à jour; c) 4.3.5relatif aux surtensions à front très rapide a été révisé. L'Annexe J relative à la coordination de l'isolement pour les surtensions à front très rapide dans les postes UHT a été ajoutée; d) l'Annexe H relative à la correction atmosphérique – correction de l'altitude a été ajoutée; e) l'Annexe I relative à la méthode d'évaluation de la forme de la surtension de foudre non normalisée a été ajoutée.
Koordinacija izolacije - 2. del: Smernice za uporabo (IEC 60071-2:2018)
Ta del standarda IEC 60071 predstavlja smernice za uporabo in obravnava izbiro izolacijske stopnje opreme ali naprav za trifazne električne sisteme. Njegov namen je podati smernice za ugotavljanje naznačenih najvišjih vrednosti za razpona I in II standarda IEC 60071-1 ter utemeljiti povezavo med temi nazivnimi vrednostmi in standardizirano najvišjo napetostjo opreme.
Ta povezava je namenjena samo koordinaciji izolacije. Zahteve za varnost ljudi niso obravnavane v tem dokumentu.
Ta dokument zajema trifazne sisteme z nazivnimi napetostmi nad 1 kV. Vrednosti, izpeljane ali predlagane v tem dokumentu, se na splošno uporabljajo samo za tovrstne sisteme. Kljub temu pa predstavljeni koncepti veljajo tudi za dvofazne in enofazne sisteme.
Ta dokument zajema dozemno, medfazno in longitudinalno izolacijo.
Ta dokument ni namenjen obravnavi rutinskih preskusov. Te morajo določiti ustrezni tehnični odbori.
Vsebina tega dokumenta strogo sledi diagramu poteka za postopek koordinacije izolacije, ki je predstavljen na sliki 1 v standardu IEC 60071-1:2006. Točke 4 do 7 se ujemajo s kvadratki na tem diagramu in podajajo podrobne informacije o konceptih, ki veljajo za postopek koordinacije izolacije, s katerim se dosežejo zahtevane stopnje vzdržljivosti.
Ta dokument poudarja, da je že na samem začetku treba upoštevati vse izvore, vse razrede in vse vrste napetostnih obremenitev med delovanjem, ne glede na razpon najvišje napetosti opreme. Šele na koncu postopka, ko je treba izbrati standardne najvišje napetosti, se uporabi načelo, pri katerem se določi standardna najvišja napetost za posamezno napetostno obremenitev med delovanjem. Prav tako se pri tem zadnjem koraku dokument nanaša na korelacijo, navedeno v standardu IEC 60071-1, med standardnimi stopnjami izolacije in najvišjo napetostjo opreme.
Ta dodatek vsebuje primere in podrobne informacije, ki pojasnjujejo ali utemeljujejo koncepte, opisane v glavnem besedilu, ter navaja osnovne uporabljene analitske tehnike.
