27、ORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the elec
28、trical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to tec
29、hnical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Orga
30、nization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technica
31、l committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publicat
32、ions is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their nationa
33、l and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment servic
34、es and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servan
35、ts or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication
36、, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility t
37、hat some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61083-2 has been prepared by IEC technical committee 42: High-voltage and high-current testing techniques.
38、 This second edition cancels and replaces the first edition, published in 1996, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: a) the test data generator software has been updated: b) the number of reference impulse waveforms included in
39、 the test data generator has been significantly increased; c) all reference values have been recalculated according to new definitions in IEC 60060-1and IEC 62475; 4 61083-2 IEC:2013 d) methods for estimating the uncertainty of parameter evaluation has been introduced and are in line with the proced
40、ure introduced in IEC 60060-2. The text of this standard is based on the following documents: FDIS Report on voting 42/318/FDIS 42/321/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been dra
41、fted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 61083 series, published under the general title Instruments and software used for measurement in high-voltage and high-current tests, can be found on the IEC website. The committee has decided that the content
42、s of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61083-2 IEC:2013
43、5 INTRODUCTION IEC 61083-1 specifies the test requirements for digital recorders. Digital recorders, like analogue oscilloscopes, are susceptible to changes in their characteristics. However, the more stringent testing (than is practical for analogue oscilloscopes) specified for digital recorders fo
44、r standard impulse voltage and current measurement has led to the accuracy of digital recorders being more clearly demonstrated. This part of IEC 61083 applies to software used to process digital records to provide the values of the relevant impulse parameters. The raw data are retained for comparis
45、on with the processed data. However, since the parameters of the test impulse (including the test value) are to be read from the processed data, it is important to establish tests to ensure that the reading of parameters is adequately performed. The problem is how to ensure this, while permitting us
46、ers to develop a wide range of techniques. This problem is further complicated by the different needs of various users, ranging from single-purpose test laboratories, for example those of a cable manufacturer who may only test a few objects which are capacitive, to large high-voltage test/research l
47、aboratories, which may perform tests on a very wide range of objects, which have a correspondingly wide range of impedances. The approach taken in this part of IEC 61083 is to provide, from a test data generator software, waveforms (and ranges of their parameters) which a user can employ to verify t
48、hat a procedure gives values within the specified ranges. To reduce the amount of testing required, the waveforms are divided into groups, and the user needs only to check those groups that are appropriate for the high-voltage and/or high-current tests to be performed in his/her laboratory. New defi
49、nitions for lightning impulse parameters and switching impulse time-to-peak evaluation are introduced in IEC 60060-1. The changes in these definitions have lead to significant changes in some of the reference values in this standard. The number of impulse records in the test data generator has been increased to cover a wider range of impulse shapes seen in on-site testing. 6 61083-2 IEC:2013 INSTRUMENTS AND SOFTWARE USED
