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

16、change of text, together with appropriate supporting comments. 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 societi

17、es and Standards Coordi-nating 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 revi

25、ssuance of amendments, corri-genda, 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 10 years. When a document is more

26、 than 10 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

27、determine whether a given document is the current edition and whether it has been amended through the issuance of amendments, corrigenda, or errata, visit the IEEE Xplore at http:/ ieeexplore .ieee .org/ or contact IEEE at the address listed previously.

By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connec

30、tion 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. Letters of Assurance may indicate whether the Submitt

31、er 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 discrim-ination to applicants desiring to obtain such licenses.Essential Patent Claims may exist for which a

The IEEE is not re-sponsible 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 whether any licensing terms or conditions provided in conne

Users of this standard are expressly advised that determination of the valid-ity of any patent rights, and the risk of infringement of such rights, is entirely their own respo

All rights reserved.IntroductionThis introduction is not part of IEEE Std C62.92.12016, IEEE Guide for the Application of Neutral Ground-ing in Electrical Utility SystemsPart I: Introduction.This

35、document is the rst part of a ve-part series of guides on the subject of electric utility system neutral grounding practices and serves as an introduction. When the series was rst approved and published, it re-placed IEEE Std 143-1954, IEEE Guide for Ground-Fault Neutralizers, Grounding of Synchrono

36、us Gener-ator Systems, and Neutral Grounding of Transmission Systems.Each of the remaining four parts addresses a speci c part of the utility system to serve as a guide for neutral grounding. The ve parts are as follows:a) IEEE Std C62.92.1, IEEE Guide for the Application of Neutral Grounding in Ele

39、ssion SystemsThis series of guides is intended for application to three-phase electrical utility systems. They provide de nitions and considerations that are general to all types of neutral grounding for electrical utility systems, as well as basic considerations of the selection of neutral groundin

40、g parameters that will provide for the con-trol of overvoltage and ground-fault current on all parts of three-phase electrical utility systems. They are not intended to be used with the grounding, for example, of industrial systems, which are covered in other guides and standards. These guides and s

41、tandards should be referenced, when appropriate, to gain a full picture of other grounding practices.This document has been revised to address comments received as part of the most recent re-a rmation bal-lot. The most signi cant changes were to correct an error in one of the equations in the captio

42、n beneath Fig-ure 1 in 6.3 and to correct an omission in the drawing itself. Equation A.2 and Equation A.3 were changed to correct arithmetic errors. Most of the other comments received during that re-a rmation ballot were editorial in nature and have been addressed. Other changes include the update

43、 of reference material publish dates that may have changed or been updated.It is impossible to give recognition to all those who have contributed to the technology and practices of grounding of power systems, because work involving the preparation of this guide has been in progress for more than 30

44、years. However, the assistance of members, past and present, of the Neutral Grounding Devices Subcommittee of the Surge Protective Devices Committee, and other similar groups with comparable purposes, should be acknowledged.1Information on references can be found in Clause 2. 7Copyright 2017 IEEE.
