This European Standard was approved by CENELEC on 2007-02-01. 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,

Foreword
The text of the Harmonization Document HD 428.4 S1:1994, prepared by the Technical Committee
CENELEC TC 14, Power transformers, was submitted to the formal vote for conversion into a
European Standard and was approved by CENELEC as EN 50464-3 on 2007-02-01.
The following date was 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) 2008-02-01
The EN 50464 series consists of the following parts, under the general title “Three-phase oil-immersed
distribution transformers 50 Hz, from 50 kVA to 2 500 kVA with highest voltage for equipment not
exceeding 36 kV” :
Part 1 General requirements
Part 2-1 Distribution transformers with cable boxes on the high-voltage and/or low-voltage
side – General requirements
Part 2-2 Distribution transformers with cable boxes on the high-voltage and/or
