13、 withdrawn (dow) 2012-07-01 This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 2004/108/EC. See Annex ZZ. IEC TC 38 decided to restructure the whole set of stan
14、d-alone standards in the IEC 60044 series and transform it into a new set of standards composed of general requirements documents and specific requirements documents. This standard is the first issue of this new series and can be regarded as a Product Family standard. It contains the general require

18、y found in the stand-alone standards of the EN 60044 series. Additionally, it introduces some technical innovations: requirements for gas-insulated instrument transformers, additional special tests, requirements for internal arc fault protection, requirements for degrees of protection by enclosure,
19、requirements for resistance to corrosion, requirements for safety and environmental concerns. Annexes ZA and ZZ have been added by CENELEC. _ BS EN 61869-1:2009EN 61869-1:2009 (E)3Endorsement notice The text of the International Standard IEC 61869-1:2007 was approved by CENELEC as a European Standar
