This European Standard was approved by CENELEC on 2009-07-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Foreword
The text of document 38/360/FDIS, future edition 1 of IEC 61869-1, prepared by IEC TC 38, Instrument
transformers, was submitted to the IEC-CENELEC parallel vote and, together with a number of editorial
modifications drafted by the Technical Committee CENELEC TC 38X, Instrument transformers, to answer
the EMC Consultant’s remarks, it was approved by CENELEC as EN 61869-1 on 2009-07-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2010-04-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-07-01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 stand-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 requirements for instrument transformers and shall be read in conjunction with the
relevant specific requirements standard for the instrument transformer concerned.
An overview of the planned set of standards is given below:

This standard covers all general requirements formerly 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,
– requirements for resistance to corrosion,
– requirements for safety and environmental concerns.
Annexes ZA and ZZ have been added by CENELEC.
