5、EE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Board. Members of the committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent
6、 a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that
7、there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state
8、of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of
9、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. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions
10、 for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is
11、brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason
12、, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration.

18、d C37.30-1997, IEEE Standard Requirements for High-Voltage Switches.) This standard is a revised and updated version of IEEE Std C37.30-1992 that incorporates improvements reflecting the state of the art in high-voltage switch technology. a)By deleting the adjective “air” from “air switch,” the docu
19、ments scope now covers switches that are insulated with media other than air. This will provide a consistent base for applying and comparing the various insulating technologies available in switches today. However, this document focuses on air switches and will require considerably more development
20、before it is the desired “generic” switch standard. b)Dielectric withstand voltages have been “unbundled” from rated maximum voltage, thus acknowledging the practice of using many different dielectric withstand capabilities for the same operating voltage, depending upon specific insulation coordinat
21、ion needs. c)Momentary current ratings are now defined in terms of a peak value, instead of the former “rms symmetrical total current.” d)The short-time ratings have been separated into a rated current magnitude and a rated duration of that current. e)Some higher temperatures are allowed in Table 2.
22、 f)Altitude correction factors are being developed by the C37.100.1 Working Group on Common Clauses. Because of the concurrent development of PC37.39, Proposed Standard for Interrupter Switches for Alternating Current Rated Above 1000 V, the clauses dealing with interrupter switches were largely lef
23、t unchanged. It is the intention of the working group to remove these clauses from this standard after PC37.39 is published. This revision is the consummation of the efforts of the C37.30 Revisions Working Group of the High-Voltage Switch Subcommittee of the Switchgear Committee of the IEEE Power En
24、gineering Society. The working group had the following membership: Roy W. Alexander, Chair Lee Bennett R. A. Brown James Domo Mike Dunagan Charles Hand Carlos Isaac E. L. Leuhring Alec C. Monroe Raymond P. OLeary Mark Pucinelli H. C. Ross Upon recommendation of the IEEE Switchgear Committee, this st
