This European Standard was approved by CENELEC on 2005-05-01. 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, Cyprus, Czech

Foreword
The text of document 2/1315/FDIS, future edition 5 of IEC 60034-3, prepared by IEC TC 2, Rotating
machinery, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 60034-3 on 2005-05-01.
This European Standard supersedes EN 60034-3:1995.
The significant technical changes with respect to EN 60034-3:1995 are as follows:
– the document has been consolidated and completely restructured. It was rewritten to a
considerable extent;
– the section on air cooled generators has been combined with that on hydrogen-cooled and liquid
cooled generators. Different requirements so far valid for air cooled generators alone were
modified in such a way that the requirements are now strictly bound to the generator ratings but
not longer to the machine type. As an example for the harmonisation which took place the short
circuit ratio of the air cooled generators were adjusted to those for the other generators. The
separate cooler sections for air cooled generators were eliminated;
– the standard was generally adjusted to the progress in generator control. The state of the art
control systems do not require the previous large power factors. They were reduced to one
minimum value instead of several value classes providing the prospects of reduced generator
costs. It was considered that standards should not work as an unnecessary cost driving factor;
– a normative Annex A has been added dealing with precautions to be taken when using hydrogen
as a coolant on turbine–type synchronous generators. Formerly only a guide was provided. It was
considered that aspects dealing with the safe operation of hydrogen cooled generators must be
taken seriously and must become normative.
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) 2006-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-05-01
Annex ZA has been added by CENELEC.
