Voltage characteristics of electricity supplied by public distribution 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 and medium voltage electricity distribution networks under normal operating conditions. This standard describes the limits or values within which the voltage characteristics can be expected to remain over the whole of the public distribution network and does not describe the average situation usually experienced by an individual network user. NOTE 1 For the definitions of low and medium voltage see 3.7 and 3.8. The European Standard does not apply under abnormal operating conditions including the following: – a temporary supply arrangement to keep the network users supplied during condition arising as a result of a fault, maintenance and construction work or to minimize the extent and duration of a loss of supply; – in 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 distribution network operator (DNO) including the limits for the emission of conducted disturbances; NOTE 2 A network user’s installation may include load as well as generation. – in exceptional situations, in particular, – exceptional weather conditions and other natural disasters, – third party interference, – acts by public authorities, – industrial actions (subject to legal requirements), – force majeure, – 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 distribution 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 This standard may be superseded in total or in part by the terms of a contract between the individual network user and the DNO.

Merkmale der Spannung in öffentlichen Elektrizitätsversorgungsnetzen

Diese Europäische Norm definiert, beschreibt und spezifiziert die wesentlichen Merkmale der Versorgungsspannung an der Übergabestelle zum Netznutzer in öffentlichen Nieder- und Mittelspannungs-Elektrizitätsversorgungsnetzen unter normalen Betriebsbedingungen. Diese Norm beschreibt die Grenzen oder Werte, innerhalb derer die Merkmale der Spannung über das gesamte öffentliche Elektrizitätsversorgungsnetz zu erwarten sind; sie beschreibt aber nicht die durchschnittliche Situation in einem öffentlichen Energieversorgungsnetz, wie sie ein einzelner Nutzer des Netzes gewöhnlich erfährt. ANMERKUNG 1 Zur Definition von Nieder- und Mittelspannung siehe 3.7 und 3.8. Diese Europäische Norm gilt nicht für von den normalen Betriebsbedingungen abweichende Betriebsbedingungen, welche die folgenden einschließen: – vorübergehende Versorgungsmaßnahmen, die angewandt werden, um Nutzer des Netzes während Bedingungen, die als Ergebnis einer Störung bzw. eines Fehlers, von Wartungs- und/oder Baumaßnahmen auftreten, weiter zu versorgen oder die angewandt werden, um das Ausmaß und die Dauer von Versorgungsausfällen zu minimieren; – Fälle, bei denen eine Anlage oder ein Gerät des Netznutzers nicht den einschlägigen Normen oder den technischen Anschlussbedingungen – aufgestellt entweder von den Behörden oder dem Netzbetreiber – entsprechen oder die Grenzwerte für die Aussendung leitungsgeführter Störgrößen überschreiten. ANMERKUNG 2 Eine Anlage des Netznutzers kann sowohl Lasten als auch Generatoren enthalten. – Ausnahmesituationen, insbesondere bei – außergewöhnlichen Wetterbedingungen und anderen Naturkatastrophen, – Störungen durch Dritte, – Maßnahmen der Behörden, – Arbeitskampfmaßnahmen (nach gesetzlichen Bestimmungen), – höherer Gewalt, – Versorgungsengpässen als Ergebnis äußerer Einflüsse. Die in dieser Norm beschriebenen Merkmale der Versorgungsspannung sind nicht dafür vorgesehen, als Werte für die Elektromagnetische Verträglichkeit (EMV) oder als Grenzwerte für die Aussendung von leitungsgeführten Störgrößen durch Anlagen oder Geräte des Netznutzers in öffentlichen Energieversorgungs-netzen verwendet zu werden. Die in dieser Norm beschriebenen Merkmale der Versorgungsspannung sind nicht dafür vorgesehen, zur Festlegung von Anforderungen in Produktnormen der angeschlossenen Geräte oder in Installationsnormen verwendet zu werden. ANMERKUNG 3 Das Betriebsverhalten eines angeschlossenen Gerätes kann beeinträchtigt werden, wenn dieses Versorgungsbedingungen ausgesetzt ist, die nicht in der Produktnorm des Gerätes berücksichtigt sind. Diese Norm kann ganz oder teilweise durch vertragliche Vereinbarungen zwischen dem einzelnen Netznutzer und dem Netzbetreiber außer Kraft gesetzt werden.

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 de distribution basse tension et moyenne tension dans des conditions normales d'exploitation. Cette norme décrit les limites ou les valeurs des caractéristiques de la tension qui peuvent être attendues sur l’ensemble du réseau public de distribution et ne décrit pas la situation moyenne habituellement rencontrée par un utilisateur du réseau. NOTE 1 Voir les définitions de la basse tension et de la moyenne tension en 3.7 et 3.8. Cette Norme Européenne ne s'applique pas dans les situations d'exploitation anormales, y compris dans les cas suivants: – conditions d'alimentation provisoires pour maintenir les utilisateurs du réseau alimentés dans une situation faisant 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 coupure d'alimentation; – non conformité de l'installation ou des équipements de l’utilisateur du réseau aux normes applicables ou aux prescriptions techniques de raccordement de charges établies soit par l'administration, soit par le Gestionnaire de Réseau de Distribution (GRD) incluant les limites d'émission de perturbations conduites; NOTE 2 L'installation d’un utilisateur du réseau peut inclure des charges aussi bien que des productions. – dans les situations exceptionnelles, en particulier, – conditions climatiques exceptionnelles et autres catastrophes naturelles, – faits provenant de tiers, – décisions officielles, – faits de grève (soumises à des obligations légales), – force majeure, – coupures 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 GRD.

1 Scope and object
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 and medium voltage electricity
distribution networks under normal operating conditions. This standard describes the limits or
values within which the voltage characteristics can be expected to remain over the whole of the
public distribution network and does not describe the average situation usually experienced by
an individual network user.
NOTE 1  For the definitions of low and medium voltage see 3.7 and 3.8.

The European Standard does not apply under abnormal operating conditions including the
following:
– a temporary supply arrangement to keep the network users supplied during condition arising
as a result of a fault, maintenance and construction work or to minimize the extent and
duration of a loss of supply;
– in 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 distribution network operator (DNO) including the limits for the emission of
conducted disturbances;
NOTE 2  A network user’s installation may include load as well as generation.

– in exceptional situations, in particular,
– exceptional weather conditions and other natural disasters,
– third party interference,
– acts by public authorities,
– industrial actions (subject to legal requirements),
– force majeure,
– 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 distribution 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 DNO.

1.2 Object
The object of this European Standard is to define and describe the characteristics of the supply
voltage concerning
– frequency,
– magnitude,
– wave form,
– symmetry of the line voltages.

– 5 – EN 50160:2007
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 levels of 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 such phenomena, e.g. voltage dips and voltage interruptions, shall be
interpreted accordingly.
