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 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.
International Standard IEC 62053-52 has been prepared by IEC technical committee 13:
Equipment for electrical energy measurement and load control.
This standard cancels and replaces the second edition of IEC 60387, published in 1992.
The main changes with respect to IEC 60387 are as follows:
• the document has been brought in line with standards established recently by TC 13;
• a few new symbols have been added.

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 62053 consists of the following parts, under the general title Electricity metering
equipment − Particular requirements:
Part 11: Electromechanical meters for active energy (classes 0,5, 1 and 2)
Part 21: Static meters for active energy (classes 1 and 2)
Part 22: Static meters for active energy (classes 0,2 S and 0,5 S)
Part 23: Static meters for reactive energy (classes 2 and 3)
Part 31: Pulse output devices for electromechanical and electronic meters (two wires only)
Part 52: Symbols
Part 61: Power consumption and voltage requirements
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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.

INTRODUCTION
The symbols in this part of IEC 62053 may be substituted for the markings given in the
different national languages. They have the advantage of explaining the necessary technical
characteristics irrespective of the country for which the meter is intended.

3.4
primary register
register of an instrument transformer-operated meter which takes into account the ratios of all
the transformers (voltage and current transformers) to which the meter is connected
NOTE The value of the energy on the primary side of the transformers is obtainable from the direct reading of the
register.
3.5
half-primary register
register of an instrument transformer-operated meter which takes into account either the
ratio(s) of the current transformer(s) or the ratio(s) of the voltage transformer(s), but not both
NOTE The value of the energy on the primary side of the transformer(s) is obtainable from the reading of the
register multiplied by an appropriate factor.
3.6
secondary register
register of an instrument transformer-operated meter which takes no account of the
transformer ratio(s)
NOTE The value of the energy on the primary side of the transformer(s) is obtainable from the reading of the
register multiplied by an appropriate factor.
