2、reword This British Standard is the official English language version of EN 61243-5:2001. It was derived by CENELEC from IEC 61243-51997. The CENELEC common modifications have been implemented at the appropriate places in the text and are indicated by common modification tags Da The UK participation
3、 in its preparation was entrusted to Technical Committee PEU78, Tools for live working, which has the responsibility to: - - aid enquirers to understand the text; present to the responsible internationalEuropean committee any enquiries on the interpretation, or proposals for change, and keep the UK
4、interests informed; monitor related international and European developments and promulgate them in the UK. - 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
5、 instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the nther, pi?h!icatinm muy contain identifiers from both systems.

30、 hermetically enclosed gas insulated switchgear in the medium voltage range. At the beginning this technique was used only for information about the voltage. With this part of IEC 61243, it is the intention to have the same level of safety for detection of the absence or presence of voltage as with
31、conventional voltage detectors. O BSI 07-2001 Page 6 EN 61243-5:2001 LIVE WORKING - VOLTAGE DETECTORS - Part 5 : Voltage detecting systems (VDS) 1 Scope This part of IEC 61243 is applicable to voltage detecting systems that are single-pole and are capacitively-coupled to live parts. They are used to
32、 detect the presence or absence of operating voltage on a.c. electrical systems for voltages from 1 kV to 52 kV, and for frequencies from 162/3 Hz to 60 Hz. This standard is also applicable to phase comparators designed for voltage detecting systems. EMC tests are not included as, at the present tim
33、e, not enough information about minimum requirements is available. NOTES 1 Except where specified otherwise, 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 voltages ere gre
34、c! !o 2 Voltage detecting systems based on fundamentally different principles (for example optical systems, resistive coupling elements) are not covered in this standard but should meet the requirements of this standard where applicable. 3 For frequencies differing from 50 Hz, the values C, and U, a
35、ccording to table 1 are valid. The threshold values for I, have to be changed accordingly. 4 If in an electrical installation it is verified that the installation is dead by other means than using a voltage detecting system, a different device which can be termed voltage indicating system may be use
36、d for service information about the voltage state with reduced requirements concerning tests for clear and reliable indication. If so, this should be clearly stated and made explicit by the manufacturer (see annex F for further details). 2 Normative references The following normative documents conta
