AMENDMENT 1
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. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 62271-100:2021 has been prepared by subcommittee 17A: Switching
devices, of IEC technical committee 17: High-voltage switchgear and controlgear.
The text of this Amendment is based on the following documents:
Draft Report on voting
17A/1406/FDIS 17A/1410/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.

described in greater detail at www.iec.ch/publications/.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or

___________
INTRODUCTION to Amendment 1
This amendment includes the following significant changes:
In IEC 62271-100:2021 there is a slight difference for the calculation of u for T10 in Table 20
c
and Table 21. The u value for T10 shall be the same for k 1,3 and k 1,5 because both
c pp pp
conditions also cover transformer limited faults. For voltage ratings higher than 170 kV u also
c
covers cases of three-phase line faults with effectively earthed neutral systems. See also the
from 1,76 to 1,765 the u values are
notes in Table 20 and Table 21. By increasing the k
af c
practically the same again for k 1,3 and k 1,5.
pp pp
Furthermore:
– The definition of terminal fault has been updated.
– The description of the time parameters for the rated operated sequence has been updated
(the parameters remained the same).
– Rated voltages 15,5; 27 and 40,5 kV added to Table 1.
– Additional criteria for dielectric test added.
– It has been made explicit that partial discharge test only is applicable to GIS and dead-tank
circuit-breakers.
– Voltage test as condition check as per 7.2.12.103 added to 7.2.12.101.
– The t for T60 are corrected to the t values of T100.
2 2
– TRV values in Table 16, Table 17, Table 18, Table 19, Table 20, Table 22, Table 23, Table
24, Table 25, Table 30 and Table F.1 have been recalculated and updated.
– Requirement on having inrush making current in the same phase as minimum arcing times
during three-phase back-to-back capacitor bank current tests.
– Requirement to perform mechanical operating tests on all releases added.
– Existing tolerance for single-phase and double-earth fault added to Table B.1.
– Tolerance for breaking current L updated in Table B.1.

3.5.130
alternative operating mechanism
Replace the existing definition (but not the note to entry) with the following new definition:
change in the power kinematic chain of the original operating mechanism or use of a different
operating mechanism which retains the same mechanical characteristics
3.7.112
terminal fault
Replace the existing definition (but not the note to entry) with the following new definition :
short-circuit on at least one of the terminals of the circuit-breaker

5.104 rated operating sequence
Replace the existing text with the following new text:
The rated operating sequence is O – t – CO – t' – CO, where
O represents an opening operation;
CO represents a close-open operating cycle with the shortest possible close-open time
such that the circuit-breaker reaches the fully closed and latched position prior to
opening.
The time parameters are as follows:
– circuit-breaker for auto-reclosing: t = 3 min and t'= 3 min (alternative values for t and t' may
be used, for example 15 s or 1 min);
– circuit-breaker for rapid auto-reclosing: t = 0,3 s and t' = 3 min (alternative values for t' may
be used, for example 15 s or 1 min);

– circuit-breaker not for auto-reclosing: t > 3 min and t' > 3 min (values for t and t' to be
specified by the manufacturer).
