(Main)Voltage characteristics of electricity supplied by public electricity networks
Voltage characteristics of electricity supplied by public electricity networks
This European Standard defines, describes and specifies the main characteristics of the voltage at a network user's supply terminals in public low voltage, medium and high voltage AC electricity networks under normal operating conditions. This standard describes the limits or values within which the voltage characteristics can be expected to remain at any supply terminal in public European electricity networks and does not describe the average situation usually experienced by an individual network user. NOTE 1 For the definitions of low, medium and high voltage see 3 (Definitions). This European Standard does not apply under abnormal operating conditions, including the following: a) a temporary supply arrangement to keep network users supplied during conditions arising as a result of a fault, maintenance and construction work, or to minimize the extent and duration of a loss of supply; b) in the case of non-compliance of a network user's installation or equipment with the relevant standards or with the technical requirements for connection, established either by the public authorities or the network operator, including the limits for the emission of conducted disturbances; NOTE 2 A network user’s installation may include load and generation. c) in exceptional situations, in particular, 1) exceptional weather conditions and other natural disasters; 2) third party interference; 3) acts by public authorities; 4) industrial actions (subject to legal requirements); 5) force majeure; 6) power shortages resulting from external events. The voltage characteristics given in this standard are not intended to be used as electromagnetic compatibility (EMC) levels or user emission limits for conducted disturbances in public electricity networks. The voltage characteristics given in this standard are not intended to be used to specify requirements in equipment product standards and in installation standards. NOTE 3 The performance of equipment might be impaired if it is subjected to supply conditions which are not specified in the equipment product standard. This standard may be superseded in total or in part by the terms of a contract between the individual network user and the network operator. NOTE 4 The sharing of complaint management and problem mitigation costs between the involved parties is outside the scope of EN 50160. Measurement methods to be applied in this standard are described in EN 61000-4-30.

Caractéristiques de la tension fournie par les réseaux publics de distribution
Cette Norme Européenne définit, décrit et spécifie, au point de livraison de l’utilisateur du réseau, les caractéristiques principales de tension fournie par un réseau public basse tension, moyenne tension et haute tension AC dans des conditions normales d'exploitation. Cette norme décrit les limites ou les valeurs des caractéristiques de la tension qui peuvent être attendues en chaque point de livraison du réseau public et ne décrit pas la situation moyenne habituellement rencontrée par un utilisateur du réseau. NOTE 1 Voir les définitions de la basse tension, moyenne tension et haute tension de 3 (Définitions). Cette Norme Européenne ne s'applique pas dans les situations d'exploitation anormales, y compris dans les cas suivants: a) conditions d'alimentation provisoires pour maintenir les utilisateurs du réseau alimentés suite à une avarie, pendant les travaux d'entretien ou de construction sur le réseau ou pour limiter l'étendue et la durée d'une interruption d'alimentation; b) non conformité de l'installation ou des équipements de l’utilisateur du réseau aux normes applicables ou aux exigences techniques de raccordement de charges établies soit par l'administration, soit par le gestionnaire de réseau incluant les limites d'émission de perturbations conduites; NOTE 2 L'installation d’un utilisateur du réseau peut inclure des charges et de la production. c) dans les situations exceptionnelles, en particulier, 1) conditions climatiques exceptionnelles et autres catastrophes naturelles, 2) faits provenant de tiers, 3) décisions officielles, 4) faits de grève (soumises à des exigences légales), 5) force majeure, 6) interruptions dues à des causes externes. Les caractéristiques de la tension données dans cette norme ne sont pas destinées à être utilisées comme des niveaux de compatibilité électromagnétique (CEM) ou comme des limitations d’émission de l'utilisateur pour les perturbations conduites dans les réseaux publics de distribution. Elles ne sont pas non plus destinées à être utilisées pour définir les exigences dans les normes de produit des équipements et les normes d’installation. NOTE 3 Les performances d’un équipement peuvent être dégradées si les conditions d’alimentation ne sont pas celles spécifiées dans la norme produit correspondante. Cette norme peut être en tout ou en partie remplacée par les termes d'un contrat conclu entre un utilisateur du réseau et le gestionnaire de réseau. NOTE 4 Le partage entre les parties de la gestion des réclamations et des coûts liés à l’atténuation des problèmes est hors du domaine d’application de l’EN 50160. Les méthodes de mesure appliquées dans la présente norme sont décrites dans l’EN 61000-4-30.

This European Standard was approved by CENELEC on 2010-03-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
This European Standard was prepared by Working Group 1, Physical characteristics of electrical energy, of the Technical Committee CENELEC TC 8X, System aspects of electrical energy supply. It was submitted to the formal vote and was approved by CENELEC as EN 50160 on 2010-03-01. This document is the result of an intensive cooperation between CENELEC and CEER, with involvement of CEER experts in TC 8X WG1 as well as in related Task Forces. This document supersedes EN 50160:2007. 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. The following dates were 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)
2011-03-01 – latest date by which the national standards conflicting with the EN have to be withdrawn
(dow)
2015-03-01 The main differences from EN 50160:2007 are: – new organization of the document by grouping clauses related to events and continuous phenomena; – modification of some definitions and completion by some new definitions; – new Clause 6 relevant to voltage characteristics in high voltage networks. This work has been deemed so important, that before submission for vote, a CENELEC enquiry has been made, where NCs had the opportunity to respond to the most essential questions resulting from the WG discussions. This enquiry resulted in an extensive number of valuable comments, which have been carefully examined for possible consideration either for the voting draft in particular or for further work within WG1 on some main issues. Following that, the draft has been revised in depth, considering in particular the comments received on: – the subclauses relevant to supply voltage changes, where a new formulation (capable of encompassing the needs expressed by the vast majority of the NCs) has been introduced, – the new Clause 6, relevant to voltage characteristics in high voltage networks, where limits for harmonics and unbalance have been changed into indicative values, as new measurement surveys are taking place in several European countries, and it has been recognized as appropriate to wait for the relevant results before considering the setting of limits.

1.1 Scope This European Standard defines, describes and specifies the main characteristics of the voltage at a network user's supply terminals in public low voltage, medium and high voltage AC electricity networks under normal operating conditions. This standard describes the limits or values within which the voltage characteristics can be expected to remain at any supply terminal in public European electricity networks and does not describe the average situation usually experienced by an individual network user. NOTE 1
For the definitions of low, medium and high voltage see 3 (Definitions). This European Standard does not apply under abnormal operating conditions, including the following: a) a temporary supply arrangement to keep network users supplied during conditions arising as a result of a fault, maintenance and construction work, or to minimize the extent and duration of a loss of supply; b) in the case of non-compliance of a network user's installation or equipment with the relevant standards or with the technical requirements for connection, established either by the public authorities or the network operator, including the limits for the emission of conducted disturbances; NOTE 2
A network user’s installation may include load and generation. c) in exceptional situations, in particular, 1) exceptional weather conditions and other natural disasters;
2) third party interference; 3) acts by public authorities;
4) industrial actions (subject to legal requirements);
5) force majeure;
6) power shortages resulting from external events. The voltage characteristics given in this standard are not intended to be used as electromagnetic compatibility (EMC) levels or user emission limits for conducted disturbances in public electricity networks. The voltage characteristics given in this standard are not intended to be used to specify requirements in equipment product standards and in installation standards. NOTE 3
The performance of equipment might be impaired if it is subjected to supply conditions which are not specified in the equipment product standard. This standard may be superseded in total or in part by the terms of a contract between the individual network user and the network operator. NOTE 4
The sharing of complaint management and problem mitigation costs between the involved parties is outside the scope of EN 50160. Measurement methods to be applied in this standard are described in EN 61000-4-30. 1.2 Object
The object of this European Standard is to define, describe and specify the characteristics of the supply voltage concerning: a) frequency; b) magnitude; c) waveform; d) symmetry of the line voltages. SIST EN 50160:2011
– 5 – EN 50160:2010
These characteristics are subject to variations during the normal operation of a supply system due to changes of load, disturbances generated by certain equipment and the occurrence of faults which are mainly caused by external events.
The characteristics vary in a manner which is random in time, with reference to any specific supply terminal, and random in location, with reference to any given instant of time. Because of these variations, the values given in this standard for the characteristics can be expected to be exceeded on a small number of occasions.
Some of the phenomena affecting the voltage are particularly unpredictable, which make it very difficult to give useful definite values for the corresponding characteristics. The values given in this standard for the voltage characteristics associated with such phenomena, e.g. voltage dips and voltage interruptions, shall be interpreted accordingly.
