In the event that an IEEE standard is translated, only the English version published by IEEE should be considered the approved IEEE standard. Official statements A state

Comments on standards Comments for revision of IEEE Sta
16、ndards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, tog

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 and the members of its societies and Standards Coo
18、rdinating 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 would like to participate in revisions to an IEEE stan

Updating of IEEE Standards documents Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance
26、 of amendments, corrigenda, or errata. An official IEEE document at any 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 ten years. When a document is more than
27、ten years old and has not undergone a revision process, it is reasonable to 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 dete

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. Letters of Assurance may indicate whether the Submitter is willing or unwi

Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further info

Introduction This introduction is not part of IEEE Std C62.92.2-2017, IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part IISynchronous Generator Systems. This document is one part of a five-part series of guides on the subj
45、ect of electric utility system neutral grounding practices. When the series was first approved and published, it replaced IEEE Std 143-1954, IEEE Guide for Ground-Fault Neutralizers, Grounding of Synchronous Generator Systems, and Neutral Grounding of Transmission Systems. In this series of document
46、s, individual considerations and practices have been given to the grounding of synchronous generator systems, generator station auxiliary systems, distribution systems, and transmission systems. The first part serves as an introduction to the topic of electric utility system neutral grounding and ea
47、ch of the remaining four parts addresses a specific part of the utility system to serve as a guide for neutral grounding. The five parts are as follows: a) IEEE Std C62.92.1, IEEE Guide for the Application of Neutral Grounding in Electrical Utility SystemsPart 1Introduction. b) IEEE Std C62.92.2, IE

This series of guides is intended for application to three-phase electric utility systems. They provide definitions and considerations that are general to all types of neutral grounding for electrical utility systems as well as the basic considerations of the selection of neutral grounding parameters t
