3、 British Standard is the English language version of EN 61243-1:1997. It was derived by CENELEC from IEC 61243-1:1993. It supersedes BS 7739-1:1994 which is withdrawn. The CENELEC common modifications have been implemented at the appropriate places in the text and are indicated by a side line in the
4、 margin. The UK participation in its preparation was entrusted to Technical Committee PEL/78, Tools for live working, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals f
5、or change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. This is one of a family of standards being developed by this technical committee. For the latest information please read the BSI Catalogue at “http:/www.bsi.org.uk”.
6、A list of organizations represented on this committee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one
7、numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publication
8、s. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue.

32、apacitive voltage detectors used in contact with the part to be tested, as a single unit including its insulating pole as covered in IEC 61235 or IEC 60855, or as a separate device completed by an adaptable insulating pole covered by IEC 61235 or IEC 60855. Other types of voltage detectors are not c
33、overed by this part of the standard. Some restrictions 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). Other types of voltage detectors are not covered by this part of standard. NOTEExcept wh
34、ere otherwise specified, all the voltages defined in this standard refer to values of phase-to-phase voltages of three-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 foll
