Designation of phase differences by hour numbers in three-phase AC systems (IEC 60152:2021)

This document specifies methods and rules for the designation of phase difference between two items in a three-phase AC system. The designations are intended to be applied in the technical documentation of industrial installations, equipment and products, and also on markings of equipment and products.

Désignation des déphasages par indices horaires des réseaux en courant alternatif triphasés (IEC 60152:2021)

L'IEC 61052:2021 spécifie les méthodes et les règles en vue de la désignation du déphasage entre deux entités dans un réseau en courant alternatif triphasé. Les désignations sont destinées à figurer dans la documentation technique des installations, matériels et produits industriels, ainsi que sur les marquages des matériels et produits.
L'IEC 61052:2021 annule et remplace la 1re édition parue en 1963. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le titre a été mis à jour en vue de refléter le contenu du nouveau document;
b) le concept d'identification des conducteurs par indices horaires a été supprimé, car il est considéré comme dépassé et qu’il existe d'autres moyens d'identification des conducteurs;
c) la définition de l’indice horaire (indice d’horloge) et celle du déphasage ont été ajoutées.

DESIGNATION OF PHASE DIFFERENCES BY
HOUR NUMBERS IN THREE-PHASE AC SYSTEMS

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

25 FOREWORD
26 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
27 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
28 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
29 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
30 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
31 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
32 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
33 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
34 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
35 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
36 consensus of opinion on the relevant subjects since each technical committee has representation from all
37 interested IEC National Committees.
38 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
39 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
40 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
41 misinterpretation by any end user.
42 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
43 transparently to the maximum extent possible in their national and regional publications. Any divergence between
44 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
45 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
46 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
47 services carried out by independent certification bodies.
48 6) All users should ensure that they have the latest edition of this publication.
49 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
50 members of its technical committees and IEC National Committees for any personal injury, property damage or
51 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
52 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
53 Publications.
54 8) Attention is drawn to the Normative references cited in this publication. Use of the referen
