Members of the committees serve voluntarily and without compensation. They a
6、re not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in participating in the development of the standard. Use of an
7、 IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is
8、 approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and h
9、as not been reaffirmed, 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. Comments for revision of IEEE Standards are welc
10、ome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions o
11、f standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any i
12、nterpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously receive
13、d formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O.

18、tted without license from IHS -,-,- iii Introduction (This introduction is not part of IEEE Std 1460-1996, IEEE Guide for the Measurement of Quasi-Static Magnetic and Electric Fields.) As an aid for groups and individuals interested in developing magnetic and/or electric field measurement protocols,
19、 this guide describes different magnetic and electric field measurement methods that can accomplish specific measurement goals. A single measurement approach is not given because the measurement strategies and instrumentation requirements will differ depending on the measurement environment of inter
20、est and the goals of a measurement program. For example, the measurement protocols and instrumentation for characterizing electric and magnetic fields from power lines will differ significantly from those for characterizing fields from video display terminals. Frequent reference is made to a compani

36、without license from IHS -,-,- This page is intentionally blank. Copyright 1997 IEEE All Rights Reserved1 IEEE Guide for the Measurement of Quasi-Static Magnetic and Electric Fields 1. Overview This guide is divided into six clauses. Clause 1 provides the overview, Clause 2 lists other standards tha
37、t are useful in applying this guide, and Clause 3 describes the characteristics of quasi-static magnetic and electric fields that are candidates for measurements. The text for Clause 3 is taken from IEEE Std 1308-1994.1 Clause 4 briefly describes the types of available quasi-static magnetic and elec
38、tric field measuring instrumentation. Clauses 5 and 6 describe specific measurement goals related to characterizing quasi-static magnetic and electric fields, respectively, and possible measurement methods for their accomplishment. Throughout this guide, the terms “magnetic field“ and “magnetic flux
39、 density“ will be considered synonymous. Annex A provides a listing of bibliographical references cited. This guide provides a listing of possible measurement goals related to characterizing quasi-static magnetic and electric fields and possible methods for their accomplishment. The fields of intere
40、st are typically produced by devices that operate at power frequency and that produce power frequency and power frequency harmonic fields, as well as devices that produce fields that are independent of the power frequency. The listings of possible goals and methods should not he considered as comple
41、te because there are many possible goals and methods for their accomplishment. The approach taken in this guide parallels a method described in B3.2 Descriptions of instrumentation, their principles of operation, definitions of terminology, calibration procedures, and a listing of sources of measure
42、ment error are given in IEEE Std 1308-1994 and should be used with this guide. Protocols for measuring magnetic and electric fields near power lines and video display terminals are given in IEEE Std 644-1994 and IEEE Std 1140-1994. 1Information on references can be found in clause 2. 2The numbers in

General characteristics of quasi-static magnetic and electric field
47、s Magnetic and electric fields produced by power lines, appliances, and other electrical equipment may be characterized according to magnitude, frequency, waveform (harmonic content), degree of polarization, spatial variation, and temporal variation.4 These characteristics are described briefly beca
48、use one or more of them may be selected for measurement, and because of their importance in specifying requirements for instrumentation used to measure the fields. Several of the field parameters may be introduced by considering magnetic fields produced by currents in three-phase power lines. Some of the same parameters are also used to characterize electric fields. In general, the magnetic field at a point in space may be represented as a rotating vector that traces an ellipse for every cycle of the currents in the conductors, as shown schematically in Figure 1 (a) B10.
