Title Rotating electrical machines - Part 18-1: Functional evaluation of insulation systems - General guidelines
Project Number 22143
Abstract/Scope IEC 60034-18-1:2010 deals with the general guidelines for functional evaluation of electrical insulation systems, used or proposed to be used in rotating electrical machines within the scope of IEC 60034-1, in order to qualify them. The main changes of this new edition with respect to the previous one are as follows: - provides general guidelines for functional evaluation of different types of windings as before but beyond that for electrical evaluation of windings which are electrically stressed by converter-supply; - is now focused on general guidelines with all technical details of procedures and qualification principles moved to the subsequent parts; - details additional general aspects of functional evaluation, particularly the statistical procedure for comparison between reference and candidate insulation systems and the evaluation of minor component or manufacturing changes; - contains a new acceptance test for verifying the expected production quality level of the insulation systems; - restricts the classification of insulation systems as a result of the functional evaluation to thermal classification.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
