This European Standard was approved by CENELEC on 2008-06-01. 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,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 14/538/CDV, future edition 1 of IEC 60076-6, prepared by IEC TC 14, Power
transformers, was submitted to the IEC-CENELEC Parallel Unique Acceptance Procedure and was
approved by CENELEC as EN 60076-6 on 2008-06-01.
This European Standard supersedes EN 60289:1994 + A11:2002.
– wide extension of the “Definitions”, “Rating” and “Tests” clauses,
– more consequent distinction between definition and rating,
– “Tests” subclauses take into account the latest revisions of relevant EN 60076 standards,
– dielectric testing of reactors is now in line with dielectric testing of transformer according to
EN 60076-3:2001,
– consequent distinction between oil-immersed and dry-type reactor,
– document offers an easier handling and is a more stand-alone document than EN 60289,
– introduction of the discharge reactor as part of Clause 9,
– introduction of the turn-to-turn overvoltage test for dry-type reactors (Annex E),
– important background information given by newly introduced informative annexes,
– Annex A (informative) – Information on shunt reactor switching and on special applications
– Annex B (informative) – Magnetic characteristic of reactors
– Annex C (informative) – Mutual reactance, coupling factor and equivalent reactances of three-
phase reactors
– Annex D (informative) – Temperature correction of losses for liquid-immersed gapped-core and
magnetically shielded air-core reactors
– Annex F (informative) – Short-circuit testing
– Annex G (informative) – Resistors – Characteristics, specification and tests.
The following dates were fixed:

– latest date by which the EN has to be implemented

at national level by publication of an identical
(dop) 2009-03-01
national standard or by endorsement

– latest date by which the national standards conflicting
(dow) 2011-06-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.
