However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents shou

Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE
16、 and the members of its societies and Standards Coordinating Committees 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 wou

By publication of this standard, no position is taken by the IEEE with resp
29、ect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement 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
30、. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination to applicants desiring to obtain such l

The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or determining wheth

Overview 1.1 Background High-voltage air switches are i
48、ntended to operate under usual service conditions unless otherwise specified. It is not uncommon for these switches to be exposed to winds that exceed those defined as usual service conditions. Users may find it necessary to define their particular service conditions to coincide with the winds in th
49、e geographic area where the switches are to be applied. Worker safety and electric system reliability are often reliant upon the position of a switch regardless of wind and weather conditions. This guide can be used to assist with specifying switches that are expected to operate in areas where wind speeds will exceed the usual service conditions. This guide will provide users and manufacturers with a common means of specifying and testing wind loads on high-voltage switches. Although the tests described in this guide can be applied on any switch, larger switches ar
