CENELEC standard voltages

IEC 60038:2009 specifies standard voltage values which are intended to serve as preferential values for the nominal voltage of electrical supply systems, and as reference values for equipment and system design. This seventh edition supersedes the sixth edition (1993), its Amendment 1 (1994) and its Amendment 2 (1997). It constitutes a technical revision. The significant technical changes are:
- the addition of the values of 230 V (50 Hz) and 230/400 V (60 Hz) to Table 1;
- the replacement of the utilization voltage range at LV by a reference to the relevant standard and an informative annex;
- the addition of the value of 30 kV to Table 3;
- the replacement of the value of 1 050 kV by 1 100 kV in Table 5.
It has the status of a horizontal standard in accordance with IEC Guide 108.

Tensions normales du CENELEC

La CEI 60038:2009 spécifie des valeurs de tension normale destinées à servir de valeurs préférentielles pour la tension nominale des réseaux d'alimentation électrique, et de valeurs de référence pour la conception des matériels et des réseaux. Cette septième édition remplace la sixième édition (1993), son amendement 1 (1994) et son amendement 2 (1997). Elle constitue une révision technique. Les modifications techniques majeures sont:
- une clarification du domaine d'application;
- l'addition des valeurs de 230 V (50 Hz) et de 230/400 V (60 Hz) au Tableau 1;
- la mise à jour du Tableau 1 pour prendre en compte la fin de la période de transition pour les valeurs de 230/400 V et de 400/690 V;
- le remplacement de la plage de la tension d'utilisation en BT par une référence à la norme appropriée et par une annexe informative;
- l'addition de la valeur de 30 kV au Tableau 3;
- le remplacement de la valeur de 1 050 kV par celle de 1 100 kV dans le Tableau 5.
Elle a le statut de norme horizontale conformément au Guide 108.

Standardne napetosti CENELEC (IEC 60038:2009, spremenjen)

IEC 60038:2009 določa standardne vrednosti napetosti, ki se uporabljajo kot prednostne vrednosti za nazivne napetosti sistemov električnega napajanja in kot referenčne vrednosti za načrtovanje opreme in sistemov. Ta sedma izdaja nadomešča šesto izdajo (1993), njeno prvo spremembo (1994) in njeno drugo spremembo (1997). Predstavlja tehnično revizijo. Večje tehnične spremembe so:
- dodatek vrednosti 230 V (50 Hz) in 230/400 V (60 Hz) v preglednico 1,
- zamenjava uporabnega razpona napetosti pri LV s sklicem na ustrezen standard in informativni dodatek,
- dodatek vrednosti 30 kV v preglednico 3,
- zamenjava vrednosti 1 050 kV s 1100 kV v razpredelnici 5.
Ima status horizontalnega standarda v skladu z Vodilom IEC 108.

Foreword

This document (EN 60038:2011) consists of the text of IEC 60038:2009 prepared by IEC/TC 8,

"Systems aspects for electrical energy supply ", together with the common modifications prepared

by CLC Technical Body 8X, "System aspects of electrical energy supply".
The following dates are fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-09-05
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-09-05

This European Standard supersedes HD 472 S1:1989 + corrigendum February 2002 + A1:1995.

In this standard, the common modifications to the International Standard are indicated by a vertical

line in the left margin of the text.
The main common modifications to IEC 60038:2009 are the following.

• All references to 60 Hz are removed in the European Standard (reason: 60 Hz is not used in

Europe for a.c. electric systems).
• The "in some countries" notes related to non-CENELEC countries are removed.

• The value of 100 kV as highest voltage for equipment corresponding to the value of 90 kV as

nominal system voltage is added to Table 4 (reason: this value already exists in EN 62271-1 and

is widely used in French transmission systems).
• Sentences containing recommendations are generally put in notes.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights.

CENELEC STANDARD VOLTAGES
1 Scope
This publication applies to

– a.c. transmission, distribution and utilization systems and equipment for use in such systems with

a standard frequency of 50 Hz having a nominal voltage above 100 V;
– a.c. and d.c. traction systems;

– a.c. and d.c. equipment having nominal voltages below 120 V a.c. or below 750 V d.c., the a.c.

voltages being intended (but not exclusively) for 50 Hz applications; such equipment covers

batteries (from primary or secondary cells), other power supply devices (a.c. or d.c.), electrical

equipment (including industrial and communication), and appliances.

NOTE Z1 Only standard frequency 50 Hz is used in Europe for public a.c. transmission and distribution systems. For

systems and equipment at 60 Hz, see IEC 60038.

This publication does not apply to voltages representing or transmitting signals or measured values.

This publication does not apply to standard voltages of components and parts used within electrical

devices or items of equipment.
This publication specifies standard voltage values which are intended to serve

− as preferential values for the nominal voltage of electrical supply systems, and

− as reference values for equipment and system design.
NOTE 1 Two main reasons have led to the values specified in this standard:

The values of nominal voltage (or highest voltage for equipment) specified in this standard are mainly based on the

historical development of electrical supply systems throughout the world, since these values turned out to be the most

common ones, and have achieved worldwide recognition;

The voltage ranges mentioned in this standard have been recognized to be the most appropriate ones as a basis for

design and testing of electrical equipment and systems.

NOTE 2 It is nevertheless the task of system and product standards to define appropriate testing values, testing

conditions and acceptance criteria.
2 Normative references

The following referenced documents are indispensable for the application 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.
