Designation of phase differences by hour numbers in three-phase AC systems
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.
Kennzeichnung der Phasenverschiebung in einem elektrischen Dreiphasensystem durch Stundenziffern
Désignation des déphasages par indices horaires des réseaux en courant alternatif triphasés
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
