Annotation of standard text IEC 60034-18-21-ed.2.0 :
IEC 60034-18-21:2012 gives test procedures for the thermal evaluation and classification of insulation systems used or proposed for use in wire-wound alternating current (a.c.) or direct current (d.c.) rotating electrical machines. The test performance of a candidate insulation system is compared to the test performance of a reference insulation system with proven service experience. The main technical changes with regard to the previous edition can be seen in the introduction of some basic statistical methods in the evaluation of comparative data. Moreover, the standard states a simpler use of different test procedures. La CEI 60034-18-21:2012 donne des procedures dessai pour levaluation thermique et la classification des systemes disolation utilises ou que lon se propose dutiliser dans les machines electriques tournantes a enroulements a fils a courant alternatif ou a courant continu. La performance dessai dun systeme disolation candidat est comparee a la performance dessai dun systeme disolation de reference dont lexperience en service a ete demontree. La principale modification technique par rapport a ledition precedente est lintroduction de certaines methodes statistiques elementaires utilisees pour levaluation des donnees comparatives. La norme presente en outre une utilisation plus simple des differentes procedures dessai.
