    23、ECHNICAL COMMISSION _ MINERAL OIL-FILLED ELECTRICAL EQUIPMENT APPLICATION OF DISSOLVED GAS ANALYSIS (DGA) TO FACTORY TESTS ON ELECTRICAL EQUIPMENT FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical

    24、committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Tech

    25、nical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governme

    26、ntal and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or a

    27、greements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international u

    28、se and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications 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 pro

    29、mote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indi

    30、cated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6

    31、) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property dama

    32、ge or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publ

    33、ication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that 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 s

    34、uch patent rights. This consolidated version of IEC 61181 consists of the second edition (2007) documents 10/675/FDIS and 10/688/RVD and its amendment 1 (2012) documents 10/881/FDIS and 10/886/RVD. It bears the edition number 2.1. The technical content is therefore identical to the base edition and

    35、its amendment and has been prepared for user convenience. A vertical line in the margin shows where the base publication has been modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. 4 61181 IEC:2007+A1:2012 International Standard IEC 61181 has

    36、been prepared by IEC technical committee 10: Fluids for electrotechnical applications. This edition includes the following significant technical changes with respect to the previous edition: a) the specific procedures used during factory tests (sampling location, sampling frequency, gas extraction a

    37、nd chromatographic analysis in the laboratory) are described in more detail; b) information is provided in Annex A concerning the residual gas contents recommended before thermal tests on power transformers, typical gas values observed during the tests and cases where gas formation during the tests

    38、was followed by problems in the transformers; c) typical values observed during chopped lightning-impulse tests on instrument transformers are indicated in Annex B. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of the

    39、 base publication and its amendments 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. IM

    40、PORTANT The “colour inside” logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this publication using a colour printer. 61181 IEC:2007+A1:2012 5 INTRODUCTION IEC t

    41、echnical committee 10, responsible for IEC 61181, has prepared guidelines for performing DGA measurements during factory testing on equipment filled with mineral insulating oil in order to ensure consistency in the industry and improve the confidence with which the results will be used. DGA is used

    42、routinely as a standard quality control procedure during and after factory tests on electrical equipment, for example during temperature-rise and chopped lightning-impulse tests, to indicate that a design meets specified requirements. Due to the small quantities of gases generated during factory tes

    43、ts, specific requirements are necessary for the sampling and analysis of oil samples and the interpretation of results. Acceptance criteria are beyond the scope of TC 10. Attention is drawn, however, to the fact that the guidelines issued by CIGRE in 1993-1995 11do not apply any more to transformers

    44、 manufactured today, the design of which having been improved. Examples of values actually observed today are indicated in Annexes A and B. 1Figures in square brackets refer to the bibliography. 6 61181 IEC:2007+A1:2012 MINERAL OIL-FILLED ELECTRICAL EQUIPMENT APPLICATION OF DISSOLVED GAS ANALYSIS (D

    45、GA) TO FACTORY TESTS ON ELECTRICAL EQUIPMENT 1 Scope This International Standard specifies oil-sampling procedures, analysis requirements and procedures, and recommends sensitivity, repeatability and accuracy criteria for the application of dissolved gas analysis (DGA) to factory testing of new powe

    46、r transformers, reactors and instrument transformers filled with mineral insulating oil when DGA testing has been specified. The most effective and useful application of DGA techniques to factory testing is during the performance of long-term tests, typically temperature-rise (heat run) and overload

    47、ing tests on power transformers and reactors, also impulse tests on instrument transformers. DGA may also be valuable for over-excitation tests run over an extended period of time. Experience with DGA results, before and after short-time dielectric tests, indicates that DGA is normally less sensitiv

    48、e than electrical and acoustic methods for detecting partial discharges. However, DGA will indicate when these partial discharges become harmful to the insulation and may be detected by inspection 2. 2 Normative references The following referenced document is indispensable for the application of thi

    49、s document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
