7、embers of the committees serve voluntarily and without compensation. They are 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
8、 an inter- est in participating in the development of the standard. Use of an 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
9、IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is 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 sub- jected to review at least every fi ve years
10、for revision or reaffi rmation. When a document is more than fi ve years old and has not been reaffi rmed, it is reasonable to conclude that its contents, although still of some value, do not wholly refl ect the present state of the art.

Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments.
12、Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specifi c 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
13、rep- resent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests.

20、e Impulse Tests.) The fi rst edition of this standard was published in 1987. The International Electrotechnical Commission (IEC) published an equivalent standard in 1991, IEC 1083-1, Digital recorders for measurements in high- voltage impulse testsPart 1: Requirements for digital recorders. From the
21、 outset there has been close liaison between the two working groups and it was agreed that each working group would try to provide its parent organization with documents that were substantially and technically the same. Liaison has been maintained with Technical Committee 10 (TC 10) of the IEEE Inst
22、rumentation and Measurement Society, Waveform Measurement and Analysis. This edition of the standard incorporates comments and the responses to questions that have been received by the working group since 1987. This standard states the performance requirements for an impulse digitizer and the tests
23、necessary to verify that these performance requirements have been met. When an impulse digitizer is used and maintained in accordance with this standard it will meet the accuracy requirements specifi ed in IEEE Std 4-1995. This standard was developed by the P1122 Working Group of the Digital Techniq
24、ues in Electrical Measure- ments Subcommittee of the Power Systems Instrumentation and Measurement Committee of the IEEE Power Engineering Society. The P1122 Working Group had the following members: T. R. McComb, Chair This standard was sponsored by the Power Systems Instrumentation and Measurement
25、Committee, which also served as the balloting committee that approved this document for submission to the IEEE Standards Board. The following persons were voting members of the balloting committee: J. Kuffel, Chair S. M. Benda-Berlijn J. Csomay K. Feser G. J. Fitzpatrick E. Gockenbach S. Grzybowski

36、Standard for Digital Recorders for Measurements in High-Voltage Impulse Tests 1. Scope This standard is applicable to digital recorders and digital oscilloscopes used for measurements during tests with high-impulse voltages and high-impulse currents. It covers the measuring characteristics and calib
37、ra- tions required to meet the measuring accuracy specifi ed in IEEE Std 4-1995 and IEEE Std C57.98-1993 B10. 1 The characteristics of general-purpose digital recorders are covered in IEEE Std 1057-1994 B9. General methods of pulse measurement are covered in IEC 60469-1 (1987-12) B4 and IEC 60469-2
38、(1987-12) B5. This standard a) Defi nes the terms specifi cally related to the digital recorders used for monitoring high-voltage and high-current impulse tests; b) Specifi es the necessary performance characteristics for such digital recorders to ensure their compli- ance with the requirements for
39、high-voltage and high-current impulse tests; c)Describes the tests and procedures that are necessary to show that these performance characteristics are within the specifi ed limits. 2.

43、t could be achieved when measuring an impulse whose peak-value is equal to the full-scale range and when there is no reduction in the effective resolution caused by non-ideal behavior of the digital recorder. Reductions in resolution caused by using less than full-scale defl ection can be quantifi e
44、d (e.g., an 8-bit recorder has a rated resolution of 1 in 256). The resolution used to record an impulse is approximately 1 in (maximum value minus minimum value). For a (maximum minus minimum) value of 198 the number of bits is reduced to 7.63 (0.37 lost bits) while for a value of 98 the number of
45、bits is equivalent to 6.61 (1.39 lost bits). The resolution is also reduced by noise and the total reduction in resolution gives an actual resolution which is the logarithm to base 2 of the (maximum value minus minimum value)/(the standard deviation of the noise times ); see equation 97 of IEEE Std
