22、lectrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote interna- tional co-operation on all questions concerning standardization in the electrical and electronic fi
23、elds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Techni- cal Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any
24、 IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organiza- tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or- ganization for Stand
25、ardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has re
26、presentation from all inter- ested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate
27、, IEC cannot be held responsible for the way in which they are used or for any misinter- pretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional
28、 publications. Any divergence be- tween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in s
29、ome areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents

40、nsulation systems of rotating electrial machines. IEC 60034-18-1 provides general guidelines for such procedures and qualification principles, whereas the subsequent parts IEC 60034-18-21, IEC 60034-18-22, IEC 60034-18-31, IEC 60034-18-32, IEC 60034-18-33, IEC 60034-18-34, IEC 60034-18-41 and IEC 60
41、034-18- 42 give detailed procedures for the various types of windings. Beyond that, part IEC 60034- 18-41 and IEC 60034-18-42 contain special test procedures for electrical evaluation of windings electrically stressed by converter-supply. The following standards provide the basis and background for
42、the development of the previous standards: IEC 60505 establishes the basis for estimating the ageing of electrical insulation systems under conditions of either electrical, thermal, mechanical, environmental stresses or combinations of these (multifactor stresses). It specifies the general principle
43、s and procedures that should be followed defining functional test and evaluation procedures. The IEC 60216 series deals with the determination of thermal endurance properties of single insulating materials. On the assumption, that the Arrhenius equations describe the rate of thermal ageing, test pro
44、cedures and analyzing instructions for getting characteristic parameters like the “Temperature index” (TI), the “Halving interval” (HIC) and the “Relative thermal endurance index” (RTE) are given. For all these parameters selected properties and accepted end-point-criteria are specified. Consequentl
45、y, a material may be assigned with more than one temperature index, derived from the measurement of different properties and the use of different end-point criteria. IEC 60085 deals with thermal evaluation of insulation systems used in electrical equipment. In particular, thermal classes of insulati
46、on systems are defined and designations are given, such as 130 (B), 155 (F) and 180 (H) for use in rotating machines belonging to IEC 60034-1. In the past, materials for insulation systems were often selected solely on the basis of thermal endurance of individual materials performed according to the
47、 IEC 60216 series. However, IEC 60085 recognizes that such selection may be used only for screening materials prior to further functional evaluation of a new insulation system which is not service-proven. Evalua- tion is performed on the basis of a comparison with a service-proven reference insulati
48、on sys- tem. Service experience is the preferred basis for assessing the thermal endurance of an in- sulation system. IEC 62539 defines statistical methods to analyse times to breakdown and breakdown voltage data obtained from electrical testing of solid insulation materials, for the purposes of cha
49、racterization of the system and comparison with other insulation systems. The methods of analysis are described for the Weibull-distribution but other distributions are also presented. 6 60034-18-1 IEC:2010 ROTATING ELECTRICAL MACHINES Part 18-1: Functional evaluation of insulation systems General guidelines 1 Scope This part of IEC 60034 deals with the general guidelines for functional evaluation of elec
