18、tional electrotechnical 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, Techni
19、cal Specifications, Technical 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.
20、 International, governmental 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)
21、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 technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommenda
22、tions 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 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end
23、 user. 4) In order to promote 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 publicat
24、ion shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7)
25、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 damage or other damage of any nature whatsoever, whether direct or indirect, or for cost
26、s (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 publication. Use of the referenced publications is indispensable for the correct applica
27、tion 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 such patent rights. International Standard IEC 60060-3 has been prepared by IEC techn
28、ical committee 42: High- voltage testing techniques. The text of this standard is based on the following documents: FDIS Report on voting 42/203/FDIS 42/204/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 pu
29、blication has been drafted in accordance with the ISO/IEC Directives, Part 2. Terms used throughout this standard which have been defined in Clause 3 are written in bold type. 60060-3 IEC:2006(E) 5 IEC 60060 consists of the following parts, under the general title High-voltage test techniques: Part
30、1: General definitions and test requirements Part 2: Measuring systems Part 3: Definitions and requirements for on-site testing The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.
31、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. A bilingual version of this publication may be issued at a later date. 6 60060-3 IEC:2006(E) INTRODUCTION The requirements specified in IE
32、C 60060-1 and IEC 60060-2 cannot always be achieved during on-site tests, due to a variety of external factors not present in factory and laboratory tests such as external electric and magnetic fields, weather conditions, etc. On-site high-voltage tests are required: as withstand tests as part of a
33、commissioning procedure on equipment to demonstrate that transport from manufacturer to site, and the erection on-site complies with manufacturers specification; as withstand tests after on-site repair, to demonstrate that the equipment has been successfully repaired, and is in a suitable condition
34、to return to service; for diagnostic purposes, e.g. PD measurement, to demonstrate if the insulation is still free from dangerous defects, and as an indication of life expectation. 60060-3 IEC:2006(E) 7 HIGH-VOLTAGE TEST TECHNIQUES Part 3: Definitions and requirements for on-site testing 1 Scope Thi
35、s part of IEC 60060 is applicable to the following on-site test voltages and in service stresses, which are in relation to IEC 60060-1: direct voltage; alternating voltage; lightning impulse voltage of aperiodic or oscillating shape; switching impulse voltage of aperiodic or oscillating shape. For s
36、pecial tests the following voltages are used: very low frequency voltage; damped alternating voltage. This standard is applicable to equipment with a highest voltage U mgreater than 1 kV. The selection of on-site test voltages, test procedures and test voltage levels for apparatus, equipment or inst
37、allations is under the responsibility of the relevant technical committee. For special applications, on-site test voltages different from those described in this standard may be specified by the relevant technical committee. NOTE 1 The different voltage waveforms listed above do not necessarily prov
38、ide equal stress on the test object. NOTE 2 The selection of the test voltage levels should take the larger tolerances and measuring uncertainties into account. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, onl
