3、itish Standard is the English language version of EN 61243-2:1997 including amendment A1:2000 and A2:2002. It was derived by CENELEC from IEC 61243-2:1995 including corrigenda June 1996, July 1999, March 2002, amendment 1:1999 and amendment 2:2002. The CENELEC common modifications have been implemen
4、ted at the appropriate places in the text. The start and finish of each common modification is indicated in the text by tags . The start and finish of text introduced or altered by amendment is indicated in the text by tags . Tags indicating changes to IEC text carry the number of the IEC amendment.
5、 For example, text altered by IEC amendment 1 is indicated by . IEC corrigendum June 1996 was incorporated within BS EN 61243-2 on publication. IEC corrigendum July 1999 replaces the previously used cleaning fluids in 6.6.3 with isopropanol, and added a note about employer responsibility. IEC corrig
6、endum March 2000 replaces reference to IEC 410:1973 in Clause 2 and C.1 with ISO 2859-1:1999. The reference to IEC 61318:1994 in C.2 was also added. The UK participation in its preparation was entrusted to Technical Committee PEL/78, Tools for live working, which has the responsibility to: aid enqui
7、rers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for 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
8、 standards being developed by this technical committee. For the latest information please read the BSI Catalogue at “http:/”. 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 th
9、e 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 numbering system to the other, publications may contain identifiers from both systems.

37、ncies from 15 Hz to 60 Hz. This part applies only to resistive voltage detectors used in contact with the part to be tested, as a single unit or as a separate device completed by an adaptable insulating pole covered in IEC 60855 or IEC 61235. Other types of voltage detectors are not covered by this
38、part of standard. Capacitive voltage detectors are covered in IEC 61243-1. The upper voltage limit is in accordance with the tests described in this part of IEC 61243. Some restrictions on their use are applicable in the case of factory-assembled switchgear and on overhead systems of electrified rai
39、lways (see Annex B). NOTE 1 Except when otherwise specified, all the voltages defined in this standard refer to phase-to-phase voltages of three-phase systems. Resistive detectors may be used in other than three-phase systems, but the applicable phase-to-phase or phase-to-earth (ground) voltage shal
40、l be used to determine the operating voltage. NOTE 2 Although this standard does not cover d.c. voltage detectors, some detectors may respond to d.c. voltage. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of t
