1、BRITISH STANDARD BS EN 60437:1998 IEC 60437: 1997 Radio interference test on high-voltage insulators The European Standard EN60437:1997 has the status of a British Standard ICS 29.080.10BSEN 60437:1998 This British Standard, having been prepared under the directionof the Electrotechnical Sector Boar
2、d, was published underthe authority of the Standards Board and comes intoeffect on 15January1998 BSI 04-1999 ISBN 0 580 29443 9 National foreword This British Standard is the English language version of EN60437:1997. It is identical with IEC60437:1997. The UK participation in its preparation was ent
3、rusted to Technical Committee PEL/36, Insulators for power systems, 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 for change, and keep the UK interests informed; mon
4、itor 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 1January1997, all IEC publications have the number60000added to the old number. For instance, IEC27-1 has been r
5、enumbered as IEC60027-1. For a period of time during the change over from one 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 referenc

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 “

This second edition incorporates that experience. It presents, in the form of an International Standard, the recommended procedures for a radio i
23、nterference test on high-voltage insulators. 1 Scope This International Standard specifies the procedure for a radio interference (RI) test carried out in a laboratory on clean and dry insulators at a frequency of0,5MHz or1MHz or, alternatively, at other frequencies between0,5MHz and2MHz. In service
24、 the RI characteristics of an insulator may be modified by the ambient conditions, particularly rainfall and other moisture, and by pollution. It is not considered feasible to specify reproducible test conditions to simulate a range of ambient conditions. Hence only tests on clean and dry insulators
