2、17-2015(Revision of IEEE Std 117-1974)IEEE Standard Test Procedure for Thermal Evaluation of Systems of Insulating Materials for Random-Wound AC Electric MachinerySponsor Rotating Machinery Committee of the IEEE Power and Energy SocietyApproved 5 December 2015IEEE-SA Standards BoardAbstract: The sta
3、ndard test procedure for the thermal evaluation and qualification of electrical insulation systems (EISs) for random-wound ac electric machinery, where thermal degradation is the dominating aging factor, is described. The relative thermal performance of a candidate EIS is compared to that of a refer
4、ence EIS. Insulation systems for such machinery with input voltage of up to 600 V at 50/60 Hz are described in this standard. A statistical method for establishing a relative life-temperature relationship for an insulation system is also described. To have any significance, the reference insulation
5、system must be supported with adequate field service data. Evaluation of insulation systems for use in air-cooled, random-wound ac electric machinery with “usual service conditions” is this procedures intent. This procedure, on its own, does not cover insulation systems such as exposure to conductin
6、g contaminates, radiation, inverter applications, or operation in oils, refrigerants, or other media that potentially degrades insulating materials.Keywords: ac electric machinery, IEEE, insulation system, random-wound, thermal evaluationThe Institute of Electrical and Electronics Engineers, Inc.3 P

17、welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertain-ing to IEEE Standards documents.

Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions also receive the concur-rence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordi-nating Committe
19、es are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is welcome to

26、r.Updating of IEEE Standards documentsUsers of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corri-genda, or errata. An official IEEE document at any
27、point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect.Every IEEE standard is subjected to review at least every 10 years. When a document is more than 10 years old and has not undergone a revision process, it is reasonable to
28、 conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE standard.In order to determine whether a given document is the current edition and whether it has bee

31、plementation of this standard may require use of subject matter covered by patent rights. By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a state
32、ment of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compens

35、ements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the valid-ity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility.

All rights reserved.IntroductionThis introduction is not part of IEEE Std 117-2015, IEEE Standard Test Procedure for Thermal Evaluation of Systems of Insulating Materials for Random-Wound AC Electric Machinery.This standard is provides a
43、n evaluation of the thermal capability of an unsealed random-wound insulation sys-tem. Other aging factorselectrical, mechanical, and environmentalare also known to be important. Test procedures for evaluating those factors, both individually and in combination with each other, will be pursued by ot
44、her working groups.This standard was updated in 2015, with specific limitations noted here: Consideration of uprating for usage to 1000 V was discussed, but not implemented in the 2015 version. This was due to concerns about uprating without adequate test data. Publications and data collection of te
45、sting up to 1000 V should be completed prior to placing it into an IEEE standard. The use of a condensation chamber is listed herein. There is a round-robin study pending that will in-vestigate the alternate use of a humidity chamber for testing. At present this standard remains with the wording of
46、condensation chamber.Comments on, and suggestions for the improvement of, this standard are welcome, and should be sent to the IEEE Standards Board (see Participants).AcknowledgementsThe committee would like to gratefully acknowledge ELTEK International Laboratories, Shermco Industries, and Von Roll
