This European Standard was approved by CENELEC on 2009-03-01. 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 17A/815/FDIS, future edition 2 of IEC 62271-100, prepared by SC 17A,
High-voltage switchgear and controlgear, of IEC TC 17, Switchgear and controlgear, was submitted to the
IEC-CENELEC parallel vote and was approved by CENELEC as EN 62271-100 on 2009-03-01.
This European Standard supersedes EN 62271-100:2001 + A1:2002 + A2:2006 + A2:2006/corrigendum
November 2006.
The main changes with respect to EN 62271-100:2001 are listed below:
– introduction of harmonised (IEC and IEEE) TRV waveshapes for rated voltages of 100 kV and above
(amendment 1 to EN 62271-100:2001);
– introduction of cable and line systems with their associated TRVs for rated voltages below 100 kV
(amendment 2 to EN 62271-100:2001);
– inclusion of IEC 61633 and IEC 62271-308.
This standard shall be read in conjunction with EN 62271-1:2008, to which it refers and which is
applicable unless otherwise specified in this standard. In order to simplify the indication of corresponding
requirements, the same numbering of clauses and subclauses is used as in EN 62271-1. Amendments to
these clauses and subclauses are given under the same references whilst additional subclauses are
numbered from 101.
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) 2009-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-03-01
Annex ZA has been added by CENELEC.
