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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

0 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 a layered substation 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 substation. The most important parts of this series define:
1. Information models for the substation 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 substation automation system (like protection relays).
2. The communication between intelligent electronic devices (IEDs) of the substation
automation system.
3. A configuration language used to describe the configuration aspects of the substation
automation system.
4. Conformance testing of the communication interfaces of the IEDs of the substation
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 needs to support 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 substations at all voltage levels.

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –

Part 3: Digital interfaces based on IEC 61850



1 Scope
This International Standard is applicable to high-voltage switchgear and controlgear (scope of
IEC SC 17A) and assemblies thereof (scope of IEC SC 17C) and specifies equipment for
digital communication with other parts of the substation 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 an 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 shall be supported
by such switchgear and controlgear, and assemblies thereof.
b) Conformance classes for the set of communication services that shall be 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.
d) An extension of the IEC 61850 series’ object model for switchgear monitoring.
NOTE 1 It is intended to integrate the extension of the IEC 61850 series’ object model for switchgear monitoring
into a further revision of the IEC 61850 series. Once this integration is completed, the relevant parts will be
removed from this standard.
The document is based on the IEC 61850 series, the horizontal standard series for
communication, and 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 2 There is a limited activity today concerning switchgear with digital interface for rated voltage levels less
than, or equal to, 52 kV. Such switchgear usually does not have integrated digital communication interfaces. If
such products are to be developed, this should be done in accordance with the present standard.
NOTE 3 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 4 For an introduction to substation 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.
