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. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropria

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

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.

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
