Rotating electrical machines - Part 3: Specific requirements for synchronous generators driven by steam turbines or combustion gas turbines

Applies to three-phase synchronous generators, having rated outputs of 10 MVA and above driven by steam turbines or combustion gas turbines. Provides common requirements as well as specific requirements for air, hydrogen or liquid cooled synchronous generators and supplements the basic requirements given in IEC 60034-1. Gives also the precautions to be taken when using hydrogen cooled generators. The scope of this new edition has been limited with respect to the previous edition.

Drehende elektrische Maschinen - Teil 3: Besondere Anforderungen an Synchrongeneratoren angetrieben durch Dampfturbinen oder Gasturbinen

Machines électriques tournantes - Partie 3: Règles spécifiques pour les alternateurs synchrones entraînés par turbines à vapeur ou par turbines à gaz à combustion

S'applique aux alternateurs triphasés synchrones de puissance assignée supérieure ou égale à 10 MVA entraînés par turbine à vapeur ou par turbine à gaz à combustion. Fournit les règles communes aux alternateurs synchrones ainsi que les règles spécifiques pour alternateurs refroidis par air, par hydrogène ou par un liquide, et constitue un complément aux règles fondamentales données dans la CEI 60034-1. Donne également les précautions à prendre lors de l'usage des alternateurs refroidis par hydrogène. Le domaine d'application de cette nouvelle édition a été limité par rapport à l'édition précédente.

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 2/1461/FDIS, future edition 6 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 2008-06-01. This European Standard supersedes EN 60034-3:2005. The significant technical changes with respect to EN 60034-3:2005 are as follows: –
the contents is now restricted to synchronous generators driven by steam turbines or combustion gas turbines, but covers as well cylindrical rotor and salient-pole generators; –
synchronous motors have been taken out of the scope of Part 3. 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)
2009-03-01 – latest date by which the national standards conflicting
with the EN have to be withdrawn
(dow)
2011-06-01 Annex ZA has been added by CENELEC. __________ Endorsement notice The text of the International Standard IEC 60034-3:2007 was approved by CENELEC as a European Standard without any modification. In the official version, for Bibliography, the following note has to be added for the standard indicated: IEC 60034-8 NOTE

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
