23、al 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 electrical and electronic
24、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 technical committees; any
25、 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 Organization for Standardi
26、zation (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 technical committee has repres
27、entation 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 Publications is accurate, IEC
28、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 national and regional publica
29、tions. Any divergence between any IEC Publication and the corresponding national or regional publication 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 I
30、EC Publication. 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, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal inju
31、ry, 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, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references c
32、ited in this publication. 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 identif
33、ying any or all such patent rights. International Standard IEC 60038 has been prepared by IEC technical committee 8: System aspects for electrical energy supply. This seventh edition supersedes the sixth edition (1993), its Amendment 1 (1994) and its Amendment 2 (1997). It constitutes a technical re
34、vision. The significant technical changes are: a clarification of the scope; the addition of the values of 230 V (50 Hz) and 230/400 V (60 Hz) to Table1; the update of Table 1 to take into account the end of the transition period for the values of 230/400 V and 400/690 V; the replacement of the util
35、ization voltage range at LV by a reference to the relevant standard and an informative annex; the addition of the value of 30 kV to Table 3; the replacement of the value of 1 050 kV by 1 100 kV in Table 5. 4 60038 IEC:2009 The text of this standard is based on the following documents: FDIS Report on
36、 voting 8/1260/FDIS 8/1264/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. It has the status of a horizontal standard in accordance with IEC Guide 108. This publication has been drafted in accordance with the ISO
37、/IEC Directives, Part 2. 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.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfir
38、med, withdrawn, replaced by a revised edition, or amended. 60038 IEC:2009 5 IEC STANDARD VOLTAGES 1 Scope This publication applies to a.c. transmission, distribution and utilization systems and equipment for use in such systems with standard frequencies 50 Hz and 60 Hz having a nominal voltage above
39、 100 V; a.c. and d.c. traction systems; a.c. and d.c. equipment having nominal voltages below 120 V a.c. or below 750 V d.c., the a.c. voltages being intended (but not exclusively) for 50 Hz and 60 Hz applications; such equipment covers batteries (from primary or secondary cells), other power supply
40、 devices (a.c. or d.c.), electrical equipment (including industrial and communication), and appliances. This publication does not apply to voltages representing or transmitting signals or measured values. This publication does not apply to standard voltages of components and parts used within electr
41、ical devices or items of equipment. This publication specifies standard voltage values which are intended to serve as preferential values for the nominal voltage of electrical supply systems, and as reference values for equipment and system design. NOTE 1 Two main reasons have led to the values spec
42、ified in this standard: The values of nominal voltage (or highest voltage for equipment) specified in this standard are mainly based on the historical development of electrical supply systems throughout the world, since these values turned out to be the most common ones, and have achieved worldwide
43、recognition; The voltage ranges mentioned in this standard have been recognized to be the most appropriate ones as a basis for design and testing of electrical equipment and systems. NOTE 2 It is nevertheless the task of system and product standards to define appropriate testing values, testing cond
44、itions and acceptance criteria. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) app
