HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –

Part 3: Digital interfaces based on IEC 61850

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 IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62271-3 has been prepared by subcommittee 17C: High-voltage
switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and
controlgear.
This second edition cancels and replaces the first edition published in 2006. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) an update to the latest edition(s) of IEC 61850 series;
(e.g. Annex B “LNs for sensors and monitoring” of edition 1 has been deleted since these
LNs are now covered by standard IEC 61850-7-4:2010)
b) an update of normative references;

---------------------- Page: 11 ----------------------

SIST EN 62271-3:2015
– 6 – IEC 62271-3:2015 © IEC 2015
c) the minimum voltage range this standard refers to, was changed from 72,5 kV to above
1 kV;
d) the description of performance tests and conformance tests became more specific;
e) the new – informative – Annex C gives an example for performance type testing;
f) 6.2.3 “transmission systems” as well as appropriate subclauses have been superseded by
standard IEC TR 61850-90-4:2013;
g) fibre optical connector type LC becomes only recommended type of fibre optic connector
in accordance with IEC TR 61850-90-4:2013;
h) electronic nameplates have been redefined as extension of LN XCBR and LN XSWI with
data objects, reflecting required additional name plate information.
NOTE A new common data class Visible String Description (VSD) will be added to the IEC 61850-7-3 to support
these new data objects.
This standard has the status of a product family standard and may be used as a normative
reference in a dedicated product standard for highvoltage switchgear and controlgear.
The text of this standard is based on the following documents:
FDIS Report on voting
17C/617/FDIS 17C/623/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 62271 series, published under the general title High voltage
switchgear and controlgear, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a

INTRODUCTION
0.1 General
This standard is a product family standard for high-voltage switchgear and controlgear and
assemblies thereof. It provides an application of the horizontal standard series IEC 61850
which details layered power utility communication architecture, in the world of high-voltage
switchgear and controlgear.
By providing tutorial material such as examples and explanations, it also gives an access for
switchgear experts to concepts and methods applied in the IEC 61850 series.
Compared to switchgear equipment, digital communication technology is subject to ongoing
changes which are expected to continue in the future. Profound experience with electronics
integrated directly into switchgear has yet to be gathered on a broader basis, as this type of
equipment is not widely spread in the industry and a change of metabolism has not yet
occurred.
This situation is taken into account in this standard by setting an appropriate validity date and
by specifying several options to most of the communication-related requirements, such as
connectors or fibres.
0.2 Position of this standard in relation to the IEC 61850 series
The IEC 61850 series is a horizontal standard intended to be used for communication and
systems in the power utility. The most important parts of this series define:
1) information models for the power utility automation system.
These information models include both the models of the switchgear (like circuit-breakers
and disconnectors) and other process equipment (like instrument transformers), and the
models of the power utility automation system (like protection relays);
2) the communication between intelligent electronic devices (IEDs) of the power utility
automation system;
3) a configuration language used to describe the configuration aspects of the power utility
automation system;
4) conformance testing of the communication interfaces of the IEDs of the power utility
automation system including their data models.
Typically, IEDs like bay level controllers interface to switchgear. In that case, the data models
of the switchgear are implemented in these devices. However, this is not the only realization.
In the case where electronics are integrated direct into switchgear, the above-mentioned data
models should be implemented within the switchgear and the switchgear supports a
communication interface.
IEC 61850, being a horizontal standard series, leaves many options open in order to support
present and future requirements of all sizes of power utility automation system at all voltage
levels.
