IEEE Standardsdocuments are developed within the Technical Committees of the IEEE Societies and the StandardsCoordinating Committees of the IEEE Standards Board. Members of the committees serve voluntarily and withoutcompensation
7、. 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 development of the standard.Use
8、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 at the time a standard
9、 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 ve years for revision or reafrmation. When a document is morethan ve years old and has not
10、 been reafrmed, it is reasonable to conclude that its 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
11、interested party, regardless of membership afliationwith 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 the

Since IEEE Standards represent a consensus of all concerned interests, it isimportant to ensure that any interpretation has also

30、 Restrictions apply. IEEE Guide for the Implementation of Inductive Coordination Mitigation Techniques and Application1. ScopeThis Guide offers users assistance in controlling or modifying the inductive environment and the susceptibility ofaffected wire-line telecommunications facilities in order to
31、 operate within the acceptable levels of steady-state orsurge-induced voltages of the environmental interface (probe wire) dened by IEEE Std 776-1987 41. Themethodology, application, and evaluation of results for mitigative techniques or devices in general are addressed for allSpecic Type A and Spec
32、ic Type B coordination methods also dened by IEEE Std 776-1987 4.2. IntroductionIn IEEE Std 776-1987 4, the recommended procedures for determining the source and type of inductive interferenceare explained. Detailed methods are provided to determine the cause and effect relationship by calculation o
33、r directmeasurement on the probe wire interface. Tables are given to set the environmental thresholds for the initiation ofinductive coordination.This guide examines the implementation of general and specic mitigation techniques. Note that long acceptedpractice suggests that both power and communica
34、tions companies design, construct, operate and maintain theirrespective systems utilizing general coordination methods, as dened in IEEE Std 776-1987 4. Some of themitigation devices and procedures that are dened as specic mitigation measures have been used by companies aseconomic trade offs against
35、 more expensive general coordination methods. This guide neither recommends norcondemns this practice. IEEE Std 776-1987 4 suggests that specic mitigation methods should not be employed asthe best engineering solution until each company is employing general coordination methods. However, users of th
36、isguide should note that implementation of any method or device should include the consideration of timeliness andeconomics irrespective of the system to which it is to be applied in order to meet each utility companys obligations totheir mutual customers and regulatory bodies, as applicable.1The nu
