Electricity metering equipment - Particular requirements - Part 23: Static meters for reactive energy (classes 2 and 3)

IEC 62053-23:2020 applies only to static var-hour meters of accuracy classes 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only.
For practical reasons, this document is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.
This document applies to electricity metering equipment designed to:
• measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC;
• have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays;
• operate with integrated or detached indicating displays, or without an indicating display;
• be installed in a specified matching socket or rack;
• optionally, provide additional functions other than those for measurement of electrical energy.
Meters designed for operation with low power instrument transformers (LPITs as defined in the IEC 61869 series) may be considered as compliant with this document only if such meters and their LPITs are tested together and meet the requirements for directly connected meters.
This document does not apply to:
• meters for which the voltage line-to-neutral derived from nominal voltages exceeds 1 000 V AC;
• meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series) when tested without such transformers;
• metering systems comprising multiple devices (except LPITs) physically remote from one another;
• portable meters;
• meters used in rolling stock, vehicles, ships and airplanes;
• laboratory and meter test equipment;
• reference standard meters;
• data interfaces to the register of the meter;
• matching sockets or racks used for installation of electricity metering equipment;
• any additional functions provided in electrical energy meters.
This document does not cover measures for the detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering).
This second edition cancels and replaces the first edition published in 2003 and its amendment 1:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Removed all meter safety requirements; the meter safety requirements are covered in IEC 62052-31:2015.
b) Replaced Ib with In; Ib is no longer used when referencing directly connected meters.
c) Moved the descriptions of all general requirements and test methods from IEC 62053-21: 2003, IEC 62053-22: 2003, IEC 62053-23: 2003, IEC 62053-24: 2003 to IEC 62052-11:2020; IEC 62053-21:2020, IEC 62053-22:2020, IEC 62053-23:2020, IEC 62053-24:2020 contain only accuracy class specific requirements.
d) Added new requirements and tests concerning:
1) measurement uncertainty and repeatability (7.3, 7.8);
2) influence of fast load current variations (9.4.12);
3) immunity to conducted differential current disturbances in the 2 kHz to 150 kHz frequency range (9.3.8).
e) Meters designed for operation with low power instrument transformers (LPITs) may be tested for compliance with this document as directly connected meters.
The reactive energy accuracy classes 2 and 3 defined in IEC 62053-23 have also been added to IEC 62053-24. The TC13

Équipement de comptage de l'électricité - Exigences particulières - Partie 23: Compteurs statiques d'énergie réactive (classes 2 et 3)

IEC 62053-23:2020 est applicable uniquement aux compteurs statiques d'énergie réactive des classes de précision 2 et 3, destinés à la mesure de l'énergie électrique réactive en courant alternatif sur les réseaux électriques en 50 Hz et 60 Hz, et à leurs essais de type. Pour des raisons pratiques, le présent document repose sur une définition conventionnelle de l'énergie réactive pour intensités et tensions sinusoïdales contenant seulement la fréquence fondamentale. Le présent document s'applique aux équipements de comptage de l'électricité conçus pour: • mesurer et piloter l'énergie électrique sur les réseaux électriques (secteur) avec une tension allant jusqu'à 1 000 V en courant alternatif; • avoir tous les éléments fonctionnels, y compris les modules complémentaires, incorporés dans ou formant un boîtier de compteur unique, à l'exception des afficheurs; • fonctionner avec des afficheurs intégrés ou séparés, ou sans afficheur; • être installés dans une embase ou un bâti correspondant spécifié; • assurer, en option, des fonctions autres que celles relatives au comptage de l'énergie électrique. Les compteurs conçus pour être utilisés avec des transformateurs de mesure de faible puissance (LPIT, Low Power Instrument Transformers, définis dans la série IEC 61869) ne peuvent être soumis à des essais de conformité au présent document que si ces compteurs et leurs LPIT sont soumis à l'essai ensemble et satisfont aux exigences relatives aux compteurs à branchement direct. Le présent document ne s'applique pas: • aux compteurs dont la tension phase-neutre déduite des tensions nominales dépasse 1 000 V en courant alternatif; • aux compteurs destinés à être connectés à des transformateurs de mesure de faible puissance (LPIT, définis dans la série IEC 61869) lorsqu'ils sont soumis à l'essai sans ces transformateurs; • aux systèmes de comptage comprenant plusieurs dispositifs (à l'exception des LPIT) physiquement éloignés les uns des autres; • aux compteurs portatifs; • aux compteurs utilisés dans le matériel roulant, les véhicules, les navires et les avions; • aux équipements de laboratoire et d'essai des compteurs; • aux compteurs étalons de référence; • aux interfaces de données avec l'élément indicateur du compteur; • aux embases ou bâtis correspondants utilisés pour l'installation des équipements de comptage de l'électricité; • à toute fonction complémentaire assurée par les compteurs d'énergie électrique. Le présent document ne couvre pas les mesures de détection et de prévention des tentatives frauduleuses de compromettre les performances du compteur (falsification). Cette deuxième édition annule et remplace la première édition parue en 2003 et son amendement 1:2016. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: voir Annexe B.

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 62053-23 has been prepared by IEC technical committee 13:

Electrical energy measurement and control.

This second edition cancels and replaces the first edition published in 2003 and its

amendment 1:2016. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition: see Annex B.
The text of this International Standard is based on the following documents:

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts in the IEC 62053 series, published under the general title Electricity metering

equipment – Particular requirements, can be found on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing

organizations may need a transitional period following publication of a new, amended or revised IEC publication in

which to make products in accordance with the new requirements and to equip themselves for conducting new or

revised tests.

It is the recommendation of the committee that the content of this publication be adopted for implementation nationally

not earlier than 2 years from the date of publication.
