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.

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 acommunication 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.---------------------- Page: 9 ----------------------

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 3: Digital interfaces based on IEC 61850
1 Scope
This part of IEC 62271 is applicable to high-voltage switchgear and controlgear for all rated
voltage levels above 1 kV and assemblies thereof and specifies equipment for digital
communication with other parts of the power utility automation and its impact on testing. This
equipment for digital communication, replacing metal parallel wiring, can be integrated into
the high-voltage switchgear, controlgear, and assemblies thereof, or can be external
equipment in order to provide compliance for existing switchgear and controlgear and
assemblies thereof with the standards of the IEC 61850 series.This International Standard is a product standard based on the IEC 61850 series. It deals with
all relevant aspects of switchgear and controlgear, and assemblies thereof with a serial
communication interface according to the IEC 61850 series. In particular it defines:
a) a selection of the information models from the IEC 61850 series that are supported by
such switchgear and controlgear, and assemblies thereof;b) conformance classes for the set of communication services that are supported by the
switchgear and controlgear, and assemblies thereof;c) modifications and extensions to type and routine tests of switchgear and controlgear, and
assemblies thereof that are required due to the serial communication interface.The standard specifies the requirements for digital communication equipment used within
high-voltage switchgear, controlgear, and assemblies thereof, as well as the relevant testing
requirements.The relevant switchgear standards of the IEC 62271 series are applicable in general, with the
additional specifications described in this standard.NOTE 1 This standard intends to promote interoperability of communication interfaces. Interchangeability is
outside the scope of this standard, as there is no requirement for it. Interchangeability is also outside the scope of
the IEC 61850 series.NOTE 2 For an introduction to power utility automation communication and the related terms, definitions and
models, refer to IEC 61850-1 which provides an overview of the objectives and requirements of the IEC 61850
series in general. IEC 61850-7-1 provides an overview of modelling techniques.2 Normative references
