FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organiza
22、tion 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 fields. To this end and in addition to other activities, IEC
23、 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 IEC National Committee interested in the subject dealt with
24、 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 Standardization (ISO) in accordance with conditions determined by agr
25、eement 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 representation from all interested IEC National Committees. 3) IEC
26、 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 cannot be held responsible for the way in which they are use
27、d 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 publications. Any divergence between any IEC Publication and the co
28、rresponding 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 IEC Publication. 6) All users should ensure that they have th
29、e 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 damage or other damage of any nature whatsoever
30、, 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 publication. Use of the referenced publications
31、 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 such patent rights. International Standard I
32、EC 61243-1 has been prepared by IEC technical committee 78: Live working. This edition includes the following major technical changes from the previous edition: a) the Scope has been extended to cover the use on electrical systems for voltages up to 765 kV a.c.; b) the notion of family of voltage de
33、tectors which are identical in terms of design and dimensions and only differ by their nominal voltages (or nominal voltage ranges) has been included; c) the classification in terms of the setting of the threshold voltage to give a clear indication has been eliminated; d) a new test set-up with bars
34、 has been introduced. Depending on the nominal voltage of the voltage detector, it is required or becomes an alternative test set-up for checking the influence of interference fields, the influence of interference voltages, the protection against bridging and the spark resistance; SANS 61243-1:2010T
35、his s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .61243-1 IEC:2003+A1:2009 5 e) the revision of specific dielectric tests has been included; f) some test procedures (clear perceptibility of audible indication, drop resistance, climatic dependenc
36、e) have been improved and completed. This consolidated version of IEC 61243-1 consists of the second edition (2003) documents 78/527/FDIS and 78/537/RVD, its amendment 1 (2009) documents 78/751/CDV and 78/794/RVC and its corrigendum of October 2005. The technical content is therefore identical to th
37、e base edition and its amendment and has been prepared for user convenience. It bears the edition number 2.1. A vertical line in the margin shows where the base publication has been modified by amendment 1. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 6124
38、3 consists of the following parts, under the general title Live working Voltage detectors: Part 1: Capacitive type to be used for voltages exceeding 1 kV a.c. Part 2: Resistive type to be used for voltages of 1 kV to 36 kV a.c. Part 3: Two-pole low-voltage type Part 5: Voltage detecting systems (VDS
39、) The committee has decided that the contents of the base publication and its amendments 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
40、med, withdrawn, replaced by a revised edition, or amended.

42、 IEC 61243 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 765 kV a.c., and frequencies of 50 Hz and/or 60 Hz. This part applies only to voltage detectors of capacitive type used in contact with the part to
43、 be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard (see 4.4.1 for general design). Other types of voltage detectors are not covered by this part of the standard. Some r
44、estrictions on their use are applicable in the case of factory-assembled switchgear and on overhead systems of electrified railways (see Annex B, instructions for use). NOTE Except where otherwise specified, all the voltages defined in this standard refer to values of phase-to-phase voltages of thre
45、e-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages should be used to determine the operating voltage. 2 Normative references The following referenced documents are indispensable for the application of this document.
