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) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 62271-1:2017 has been prepared by IEC technical committee 17:
High-voltage switchgear and controlgear.
The text of this Amendment is based on the following documents:
FDIS Report on voting
17/1106/FDIS 17/1112/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this Amendment is English.

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/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,
• replaced by a revised edition, or
• amended.

6.4.1 General
Replace the existing text of this subclause with the following:
Switchgear and controlgear include all auxiliary and control equipment and circuits, including
but not limited to, electronic controls, supervision, monitoring and communication.
Auxiliary and control equipment and circuits shall operate normally when the voltage measured
during operation at the supply terminals of the auxiliary and control equipment and circuits:
• is within 85 % to 110 % of rated supply voltage (U );
a
• in the case of DC, a ripple voltage is not greater than 5 % of U ;
a
• is free of the voltage dips and interruptions which exceed the limits declared by the
manufacturer according to IEC 61000-4-29 (DC supply voltage) and IEC 61000-4-11
(AC supply voltage).
In case of supply interruptions (also during operations) that exceed the duration limits declared
by the manufacturer for normal operation:
• there shall be no false operation, false alarms or false remote signalling resulting from the
interruption or re-instatement of the supply;
• the manufacturer shall state the behaviour of the device when the supply voltage gets
interrupted (for example impact on internal energy storage);
• the manufacturer shall state the behaviour of the device when the supply voltage returns;
• subsequent actions shall only be completed in response to a new valid operational command
(where applicable).
The fulfilment of the above conditions can be demonstrated at any convenient dip duration that
exceeds the declared limit.
NOTE 1 Possible actions can be:
a) completing the pending action without manual intervention such that the equipment achieves a defined, safe
operating state for example open, closed, charged, discharged;
b) manual intervention such that the equipment achieves a defined, safe operating state for example open, closed,
charged, discharged;
c) completing the action after giving another command for the same switching operation that was interrupted.

– 4 – IEC 62271-1:2017/AMD1:2021
© IEC 2021
This choice can also be dependent on the duration of the interruption.
Specific conditions are given in 6.9 for shunt closing releases, shunt opening releases and
under-voltage releases.
For supply voltages lower than the minimum stated above, precautions shall be taken to prevent
any damage to electronic equipment and/or unsafe operation.
Requirements for the interface with digital communication that ensure compliance with
IEC 61850 (all parts) [23] are detailed in IEC 62271-3 [24].
NOTE 2 The logical nodes in IEC 62271-3:2015 (XCBR, XSWI) and their additional data objects described in
Annex B of IEC 62271-3:2015 cover only some properties required by the electronic nameplates of some switchgear
and controlgear of the IEC 62271 series of standards. The other properties required for the physical nameplate,
tendering, quotation and ordering phases are not covered.
