IEC 60034-18-32:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60034-18-32:2022 edition 2.0 and the previous IEC 60034-18-32:2010 edition 1.0. Futhermore, comments from IEC TC 2 experts are provided to explain the reasons of the most relevant changes. IEC 60034-18-32:2022 describes qualification procedures for the evaluation of electrical endurance of insulation systems for use in rotating electrical machines using form-wound windings energized with sinusoidal power frequency voltage. The test procedures for the main wall insulation are comparative in nature, such that the performance of a candidate insulation system is compared to that of a reference insulation system with proven service experience. If no reference system is available, the diagram in Annex A is available for use. The qualification procedures of inverter duty insulation system for form-wound windings can be found in IEC 60034-18-42 or IEC 60034-18-41. A new and informative test procedure for the stress control system is introduced and defined in Annex B. This second edition cancels and replaces the first edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition: a. Title modified. b. Simplification of clauses. c. Reduction in the number of test procedures. d. Inclusion of full bars and coils as test objects. e. A new clause dealing with failures and failure criteria. IEC 60034-18-32:2022 decrit les procedures de qualification pour levaluation de lendurance electrique des systemes disolation utilises dans les machines electriques tournantes a enroulements preformes sous tension sinusoidale a la frequence dalimentation. Les procedures dessai pour lisolation principale sont comparatives, puisque les performances dun systeme disolation candidat sont comparees a celles dun systeme disolation de reference dont lexperience en service a ete demontree. Si aucun systeme de reference nest disponible, lAnnexe A decrit un diagramme utilisable. Les procedures de qualification dun systeme disolation donduleur pour enroulements preformes peuvent etre consultees dans lIEC 60034-18-42 ou lIEC 60034-18-41. Une nouvelle procedure dessai informative pour systemes de controle de contrainte est introduite et definie a lAnnexe B. Cette deuxieme edition annule et remplace la premiere edition parue en 2010. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a. modification du titre; b. simplification des articles; c. diminution du nombre de procedures dessai; d. inclusion de barres et bobines completes comme eprouvettes; e. ajout dun article qui traite des defaillances et des criteres de defaillance.
