The existenc

5、e 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 at the time a standard is approved and issued is subject to changebrought a

6、bout 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 ve years for revision or reafrmation. When a document is morethan ve years old, and has not been reafrmed, it is reasonable to conclude that it

7、s contents, although still of somevalue, do not wholly reect 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 IEEE Standards are welcome from any interested party, regardless of membership afliation

8、with 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 meaning of portions of standards as they relate tospecic applications. When the need for in

9、terpretations 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 ensure that any interpretation has also received the concurrence of a balance of interests.

10、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 consideration.Comments on standards and requests for interpretations should be addressed to:Secr

14、tituting Gapped Silicon-Carbide for Valve-Type, todistinguish it from a guide for the application of metal-oxide surge arresters.2) A new section 3.12, Protection of Gas-Insulated Substations, has been added.3) Sections 2.1.1, 3.10, 4.7, and 4.10 have been rewritten.4) Appendix A has been updated, a

15、s well as Tables 1 and 6, which has been renumbered as Table 7 and modiedto include the Heavy Duty Distribution Surge Arrester.5) Denitions D4.4 and D4.5 have been revised and renumbered D5.3 and D5.4 respectively (the original D4.3was deleted).6) New references were added, consistent with new and r

16、evised sections.7) A new Appendix E, Coefcient of grounding (COG) Calculations, has been added.8) A new Appendix F, Arrester Stroke CurrentsArresters Connected to Distribution Lines, has been added.This document was processed by Working Group 3.4.14 of the Application of Surge Protective DevicesSubc

Scope and References1.1 ScopeThis standard covers the applicati

31、on of gapped silicon-carbide surge arresters (see ANSI/IEEE Std C62.1-1984 1)1to safeguard electric power equipment against the hazards of abnormally high voltage surges of various origins. Suchovervoltages may cause ash-overs and serious damage to equipment, thereby jeopardizing the supply of power

32、 tousers. It is essential to prevent this by the proper coordination of surge protective devices with the insulation strengthof the protected equipment.The subject is a broad one with many ramications, and it would require a volume of considerable bulk to explain allpossible cases in detail. Section

33、 3 of this standard covers the basic cases for stations used to supply and switch electricpower transmission, subtransmission, or distribution feeders. Information is included in Section 4 on application ofarresters for protection of overhead distribution systems, both open-wire and spacer cable; un

34、derground system cables;all distribution transformers; and other electric distribution equipment.Step-by-step directions toward proper solutions for various applications are provided. For many cases the prescribedsteps are adequate. Complex situations or special situations requiring study by experie

35、nced engineers are described,but specic solutions may not be given. These procedures are based on theoretical studies, test results, and experience.1.2 ReferencesWhen American National Standards referred to in this document are superseded by a revision approved by theAmerican National Standards Inst
