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.

INTRODUCTION
It is mainly large customers and regulations which confirm the need for data availability over
the life cycle of the high-voltage switchgear and controlgear. For that digital standardized high-
voltage switchgear and controlgear product descriptions and product properties are increasingly
required to minimize data transfer, migration and re-formatting. This applies to all domains such
as generation, transmission, distribution, consumption, and all life cycle phases such as design,
planning, procurement, operation, maintenance, dismantling, etc.
Multiple associations or groups of actors have launched different initiatives, external to
standardization bodies, to try to respond to this demand but, due to the lack of standardisation
of device classes and properties, the situation is not satisfactory neither for customers, nor for
manufacturers nor for recyclers and waste managers.
The works and associated documents aim to solve interoperability issues met during data
migration as expected by IEC TC 17 standards and along a whole life cycle of a high-voltage
switchgear and controlgear. They even influence the future lives of their used materials, by
different stakeholders.
IEC TC 17, which deals with high-voltage switchgear and controlgear, decided to extend initial
work to take into account consideration of required properties during enquiries, tenders and
orders as shown in Figure 1.
Initial work by TC 17 highlighted inconsistencies between high-voltage switchgear and
controlgear standards such as different names for the same property, different definitions for
the same property, different units for the same property, and even several properties within
summarized in one.
In subsequent work, the mapping was extended to the properties from all IEC TC 17 standards
and any other useful standards dealing with high-voltage components implemented inside
switching devices and assemblies. This mapping is no longer limited to the properties defined
by the nameplates and considers properties for information exchanges during enquiries,
tenders, and orders.
To harmonize product description, IEC TC 17 proposes a new consistent solution within this
document.
The purpose of this document is to describe the process of the catalogue data from the mapping
of IEC TC 17 standards to the data intended to be implemented in IEC Common Data Dictionary
(IEC CDD) using ParcelMaker™ tool, as follows:
– Create a spreadsheet database.
• Review of properties of TC 17 standards and when possible associated standards.
– Define source database (IEV, glossary, ISO OBP, etc).
– Define device classes and properties for each high-voltage switchgear and
controlgear standard.
– Follow relevant attributes of properties for users as defined by IEC 61360.
– Create potential other digital representation supporting database verification and bringing
awareness of available digital material awaiting the final stage IEC CDD for its maintenance.

be used if they can be shown to lead to the same results.
– Feed ParcelMaker™ spreadsheet tool with the support of the IEC SC 3D to provide a basis
for introduction of the high-voltage switchgear and controlgear classes and properties into
the IEC 61360 database maintained by IEC/SC 3D (see http://std.iec.ch/iec61360).
– Raise awareness on value created by such catalogue data assuming to feed many digital
twins along the whole life cycle of high-voltage switchgear and controlgear (see Annex C).
This document is not intended to establish a hierarchy of classes called classification.
The intended benefits of this document are to:
– solve interoperability issues;
– reuse digital properties defined by IEC TC 17 standards;
– reduce the costs, time and efforts of mapping data for each customer request;
– optimize the workflow of industrial stakeholders’ exchanges;
– minimize duplication of articles in customer inventories and in databases;
– minimize losses and misinterpretation of data during exchanges;
– facilitate the selection of a product, especially regarding reliability and safety;
– give access to product data everywhere regardless of country, language and culture;
– provide product data related to environmental aspects such as material declaration;
– contribute to the fast growth of the e-business by simplifying the development of
e-Catalogue allowing the differentiation of products performances, certificates, etc.;
– e-Commerce: use of electronic networks to exchange information, products, services and
payments for commercial and communication purposes between individuals (consumers)
and businesses, between businesses themselves.

1 Scope
This part of IEC 62271 relates to high-voltage switchgear and controlgear for all rated voltage
levels above 1 kV AC and 1,5 kV DC and assemblies thereof and provides materials for the
reference dictionary for all products covered by the IEC 62271 series.
This dictionary is a preliminary work which can be used to facilitate exchanges in digital format
of data related to high-voltage switchgear and controlgear components, devices, equipment,
and assemblies of the power systems.
Such a dictionary improves the interoperability of the power systems required for these data
exchanges along the power system lifetime and over its life cycle.
Each property has an unambiguously defined meaning and name, and where relevant, a defined
value list, a defined format, and a defined unit.
This document defines, digitalizes and then summarizes the properties related to high-voltage
switchgear and controlgear nameplates and information usually exchanged during the
enquiries, tenders, and orders life phases defined by IEC TC 17 standards of physical elements.
The intention is not to cover manufacturer specific features.
The intention is not to cover IEC TC 17 standards dealing only with assessment methodology
(calculation, tests, rules, etc.).
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies.
For undated references, the latest edition of the referenced document (including any
amendments) applies.
IEC 61360-1:2017, Standard data element types with associated classification scheme - Part 1:
Definitions - Principles and methods
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following
addresses:
– IEC Electropedia: available at https://www.electropedia.org/
– ISO Online browsing platform: available at https://www.iso.org/obp
3.1
attribute
data element for description of a property, a relation or a device class
EXAMPLE The name of a property, the code of a class, the measure unit of a property.
3.2
block (of properties)
collection of properties describing one common aspect of the device class
Note 1 to entry: A block is a feature class in the sense of IEC 61360-1 and ISO 13584-42 [67].
EXAMPLE Diagnostic functions, control circuit.
[SOURCE: IEC 62683:2017, 3.2]
3.3
cardinality
pattern defining the number of times a concept reoccurs within a description
Note 1 to entry: Cardinality allows a block of properties contained in a list of properties to be used more than once
for a particular transaction in order to describe, for example, a device with several different outputs or more than one
process cases.
Note 2 to entry: Cardinality is defined by IEC 61987-10 [32].
3.4
classification
systematic division of a set of items into subsets according to their difference in some
predetermined characteristics
3.5
class
abstraction of a set of similar products
Note 1 to entry: A product that complies with the abstraction defined by a class is called a class member.
Note 2 to entry: A class is an intentional concept that can take different extensional meanings in different contexts.
EXAMPLE The set of products used by a particular enterprise and the set of all ISO-standardized products are two
examples of contexts. In these two contexts (the particular enterprise and ISO), the set of products that are
considered as members of the single ball bearing class can be different, in particular because employees of each
enterprise ignore a number of existing single ball bearing products.
Note 3 to entry: Classes are structured by class inclusion relationships.
Note 4 to entry: A class of products is a general concept as defined in ISO 1087-1. Thus, it is advisable that the
rules defined in ISO 704 be used for defining the designation and definition attributes of classes of products.
Note 5 to entry: In the context of the ISO 13584 series, a class is either a characterization class, associated with
properties and usable for characterizing products, or a categorization class, not associated with properties and not
usable for characterizing products.
[SOURCE: IEC 61360-2:2012, 3.6]
3.6
device
material element or assembly of such elements intended to perform a required function
Note 1 to entry: In this document, a device corresponds to a high-voltage switchgear and controlgear.
[SOURCE: IEC 60050-151:2001 [3], 151-11-20, modified – Note replaced with a new note.]
3.7
device class
set of properties which gives a description of a device
Note 1 to entry: For this document device classes are represented by the devices covered by the TC 17 standards
such as switching devices, assemblies, if any operating devices. A property can characterize functional aspect or
physical aspect.
3.8
polymorphism
pattern that allows substitution of a single concept in the same context by a different more
specific (specialized) concept
Note 1 to entry: A specialized polymorphic block of properties can replace a more generic one in the same context.
A polymorphic operator (control property) can act in selecting between of various specializations.
Note 2 to entry: Polymorphism is defined by IEC 61987-10 [32].
3.9
property
defined parameter suitable for the description and differentiation of a specific characteristic
describing an aspect of class
4 Normal and special service conditions
IEC 62271-1 [34] and its related product standards have been used to identify the properties of
respective service conditions.
5 Ratings
IEC 62271-1 [34] and its related product standard have been used to identify the properties of
ratings. The property name of a rating starts by “rated….”.
6 Design and construction
6.1 General
The attributes are in accordance with IEC 61360-1.
Based on the IEC 61360-1 data model, the structured data called cardinality and polymorphism
can be used.
The IEC Common Data Dictionary (IEC CDD) comprises seven dictionaries (status as at
05/2025) over all IEC technical committees. Usually, those databases include the properties
related to the design and the nameplate but not the full life cycle stage of the covered electrical
equipment. Figure 1 mentions the clause numbers from the IEC 62271 series of standards [34]
to [57], [63] and [64] for each life cycle stage.
Figure 1 – Scope covered by this document
This Clause 6 deals with the actions carried out to identify and structure data for this document
before, in a second step, looking at how the non-covered life phases would be addressed
(Annex A).
The identified and structured properties from IEC TC 17, SC 32A, SC 36A, and TC 38 standards
have been summarized in accordance with a structure shown in Figure 2 for better readability.
Each condition when applicable has been considered.
Figure 2 – List of IEC TC17, SC32A, SC36A, and TC38 standards used for this document
Figure 2 identifies several device classes such as:
– a device class of properties from the system;
– a device class for high-voltage equipment nameplate;
– a device class for information exchanges during procurement phases (Enquiries (E),
Tenders (T), Orders (O));
– a device class if required differentiating the switching and operating devices.
The equipment of electrical power systems requires a lot of information for which the information
from the switching device must be recalled for the assemblies. All IEC TC17 standards do not
address this topic identically. Some of them clearly mentioned a list of properties from other
standard(s) while others are mentioned if applicable.
The list of properties cannot refer to a specific list varying according to application and
according to the bill of materials of the high-voltage equipment.
The delivered database aims to consider what is mentioned inside the IEC TC 17 standards of
the switchgear and controlgear, and a few associated components used within switching
devices and assemblies such as high-voltage fuses, measurements transformers and bushings.
A spreadsheet maps all TC17 properties with associated attributes as follows:
– Property name
– Identifier (ISO/IEC 6523-1 [71] IRDI starts with 0112/2///62271# and allocated codes by
IEC SC 3D are from KKA000 to KKZ000)
– Acronym (IEC 61360-1)
– Digital interface (name identified within IEC 61850 [27], [28] and CIM series of standards)
– Preferedname (IEC 61360-1)
– Synonymous (IEC 61360-1)
– DefinitionEN (IEC 61360-1)
– DefinitionFR (IEC 61360-1)
– DefinitionDE (IEC 61360-1)
– DefinitionCN (IEC 61360-1)
– Source document (of the definition) (IEC 61360-1)
– Data_type (IEC 61360-1)
– Value_format (IEC 61360-1)
– Multiplier_of_unit
– Unit_of_measure (IEC 61360-1)
– Value_list (IEC 61360-1)
6.2 Process
Figure 3 details the general process mapping and structuring digital properties of the TC 17

standards, needing several digital formats up to “ParcelMaker™”, a Microsoft Excel plug-in
for IEC Common Data Dictionary (CDD).
ParcelMaker™ feeding the IEC Common Data Dictionary (IEC CDD) is covered by IEC SC 3D. ®
ParcelMaker™ is a plug-in software for Microsoft Excel , structuring properties in a rigorous
manner to upload the database automatically into the IEC CDD. At the time of writing of this
document all properties from IEC TC 17 standards are within ParcelMaker™ (properties and
respective definitions in four languages (EN, FR, DE, CN)), with, when identified and existing,
their value list, acronym, unit, IEC 61850 [27] [28] logical node, ecl@ss IRDI. It is encouraged
that terms and definitions in DE and CN be verified by native speakers. The data can be
accessed through the following link: IEC CDD Test database.

products may be used if they can be shown to lead to the same results.
Figure 3 – General process from data mapping and drafting IEC CDD
6.3 Criteria for naming properties
To maintain consistency and clarity in the naming of properties, terms from product standards
have been studied. When evidence of a similar meaning has been identified, the naming of
properties has been harmonized otherwise both have been kept.
Very often Clause 10 of the IEC 62271 series specifies a property without an existing definition.
This required the checking in other standards or databases as listed in the bibliography.
Synonymous names can be associated with the property name when well established terms are
used on the market.
7 Block of properties
A property within a block describes one common aspect covered by the definition of this block.
The list of blocks of properties will be defined automatically when ParcelMaker™ is filled,
considering specific block of properties defined for TC 17 as shown Table 1 and Table 2.

8 Device classes
8.1 Device class attributes
The attributes of the device classes are in accordance with IEC 61360-1.
All device classes in this document have the following attributes:
– identifier,
– preferred name,
– definition,
– synonymous name,
– source document.
The list of device classes for all properties will be defined automatically when ParcelMaker™ is
filled.
NOTE The synonymous names are limited to those necessary to avoid confusion when selecting a device class.
8.2 Classification of high-voltage switchgear and controlgear
Figure 1 gives the classification of the high-voltage switchgear and controlgear domain based
on the corresponding product standards. Table 3 shows detailed classification considered for
all standards, while the block for the classification KAA102 is applicable for IEC 62271-102 [36].
The downstream classification for each standard deals with the nameplate of the switchgear, if
any to the nameplate of the operating device and with the information to be given during
enquiries, tenders, and orders. All properties can be subjected to conditions which have been
considered for the mapping of properties but not in IEC CDD test database.

IEC TC 17 standards cover switching devices and assemblies, which require information for
components that do not yet have their own catalogue data. Some standards also specify the
properties required when integrating sub-assemblies, but others do not. Where this is not
specified and the properties of other sub-assemblies are required, Table B.1 shows possible
relationships between the parts, the switching devices and the assemblies.
9 Device properties
The properties from the IEC TC 17 standards defined in 6.1 are listed in Annex A. These
properties are the standardized properties of physical elements and do not correspond to
properties related to functional requirements or description of user expectations as explained
in Annex B.
