Rotating electrical machines - Part 18-42: Partial discharge resistant electrical insulation systems (Type II) used in rotating electrical machines fed from voltage converters - Qualification tests

IEC/TS 60034-18-42:2008 defines criteria for assessing the insulation system of stator/rotor windings of single or polyphase AC machines which are subjected to repetitive impulse voltages, such as pulse width modulation converters, and expected to withstand partial discharge activity during service. It specifies electrical qualification and acceptance tests on representative samples which verify fitness for operation with voltage-source converters.

Machines électriques tournantes - Partie 18-42: Systèmes d'isolation électrique résistants aux décharges partielles (Type II) utilisés dans des machines électriques tournantes alimentées par convertisseurs de tension - Essais de qualification

La CEI/TS 60034-18-42:2008 définit les critères d'évaluation du système d'isolation des enroulements statorique et rotorique des machines à courant alternatif monophasées ou polyphasées qui sont soumises à des tensions de choc répétitives, comme par exemple les convertisseurs à modulation de largeur d'impulsion, et susceptibles d'endurer des décharges partielles pendant leur fonctionnement. Elle spécifie des essais de qualification électrique et d'acceptation réalisés sur des échantillons représentatifs, en vue de vérifier leur adéquation à un fonctionnement avec des convertisseurs de source de tension.

Električni rotacijski stroji - 18-42. del: Električni izolacijski sistemi, odporni proti delni razelektritvi (tip II), ki se uporabljajo v električnih rotacijskih strojih, napajanih prek napetostnih pretvornikov - Preskusi zahtevanih pogojev (IEC 60034-18-42:2017)

Standard IEC/TS 60034-18-42:2008 določa merila za ocenjevanje izolacijskega sistema navitja statorja/rotorja enofaznih ali večfaznih strojev na izmenični tok, ki so izpostavljeni ponavljajočim se impulznim napetostim, kot so pretvorniki s pulzno-širinsko modulacijo, in ki med obratovanjem predvidoma prenesejo delno izpraznitev. Določa električno kvalifikacijo in preskuse sprejemljivosti pri reprezentativnih vzorcih, s čimer se preveri primernost stroja za delovanje z napetostnimi pretvorniki.
