Members of the committees serve voluntarily
5、and withoutcompensation. They are not necessarily members of the Institute. The standards developed within IEEE represent aconsensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that haveexpressed an interest in participating in the developme
6、nt of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no otherways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEEStandard. Furthermore, the viewpoint expressed
7、 at the time a standard is approved and issued is subject to changebrought about through developments in the state of the art and comments received from users of the standard. EveryIEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is moreth
8、an five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of somevalue, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have thelatest edition of any IEEE Standard.Comments for revision of IEE
9、E Standards are welcome from any interested party, regardless of membership affiliationwith IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together withappropriate supporting comments.Interpretations: Occasionally questions may arise regarding the mean
10、ing of portions of standards as they relate tospecific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiateaction to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it isimportant to ens
11、ure that any interpretation has also received the concurrence of a balance of interests. For this reasonIEEE and the members of its technical committees are not able to provide an instant response to interpretation requestsexcept in those cases where the matter has previously received formal conside

For these and otherconditions, the switch manufacturer should be consulted.4.4 Selection of insulation levelThe
44、 selection of the insulation level for air switches on systems of various nominal voltages is a function of the degreeof surge protection, the insulation level of associated equipment such as circuit breakers and transformers, and thedegree of airborne contamination anticipated. Since insulators may

Thepreferred rated maximum voltages (given in kilovolts, rms) for switches and bus supports, and their correspondingpower frequency withstand ratings and lightning impulse withstand ratings,
49、are given in tables 1 and 6 of ANSIC37.32-1990. ANSI C37.32-1990 requires that the open-gap withstand be at least 110% of rated withstand to ground, and that thephase-to-ground withstand be at least 100% of the rated withstand to ground. There is no upper limit placed onwithstand voltages, which means it is possible that the phase-to-ground withstand could be higher than the open-gapwithstand.If a switch is overinsulated, that is, if the withstand capability of the switch insulation to ground is higher than thewithstand capability of the switch open gap, rod gaps or surge pro
