This European Standard was approved by CENELEC on 2011-08-17. 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 CEN-CENELEC Management Centre 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 CEN-CENELEC Management Centre has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Foreword
The text of document 38/411/FDIS, future edition 1 of IEC 61869-5, prepared by IEC/TC 38, "Instrument
transformers", was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
The following dates are 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) 2012-05-17
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-08-17
This European Standard supersedes EN 60044-5:2004 regarding capacitor voltage transformers.
transformers - General Requirements.
This Part 5 follows the structure of EN 61869-1 and supplements or modifies its corresponding clauses.
When a particular clause/subclause of Part 1 is not mentioned in this Part 5, that clause/subclause
applies as far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the
relevant text in Part 1 shall be adapted accordingly.
For additional clauses, subclauses, figures, tables, annexes or notes, the following numbering system is
used:
– clauses, subclauses, tables, figures and notes that are numbered starting from 501 are additional to
those in Part 1;
– additional annexes are lettered 5A, 5B, etc.
Annex ZZ of EN 61869-1 is not applicable for this part of the series.
An overview of the planned set of standards at the date of publication of this document is given
below. The updated list of standards prepared by IEC TC38 is available at the website:
www.iec.ch.
