This European Standard was approved by CENELEC on 2011-05-26. 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, Croatia, 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 22F/217/CDV, future edition 2 of IEC 61954, prepared by SC 22F, Power
electronics for electrical transmission and distribution systems, of IEC TC 22, Power electronic systems
and equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 61954 on 2011-05-26.
This European Standard supersedes EN 61954:1999 + A1:2003.
EN 61954 :2011 includes the following significant technical changes with respect to
EN 61954:1999 + A1:2003:
a) Definitions of terms “thyristor level”, “valve section”, “valve base electronics” and ”redundant thyristor
levels” have been changed for clarification.
b) Conditions of testing thyristor valve sections instead of a complete thyristor valve have been defined.
c) The requirement has been added that if, following a type test, one thyristor level has become short-
circuited, then the failed level shall be restored and this type test repeated.
d) The time period of increasing the initial test voltage from 50 % to 100 % during type a.c. dielectric tests
on TSC, TCR or TSR valves has been set equal to approximately 10 s.
e) The duration of test voltage Uts2 during type a.c.-d.c. dielectric tests between TSC valve terminals and
earth as well as the duration of test voltage Utvv2 during dielectric tests between TSC valves (for MVU
only) has been changed from 30 min to 3 h.
f) The reference on the number of pulses per minute of the periodic partial discharge recorded during
a.c.-d.c. dielectric tests on TSC valves and exceeding the permissible level has been deleted.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
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) 2012-02-26
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-05-26
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 61954:2011 was approved by CENELEC as a European
Standard without any modification.
