EN 61000-2-12:2003

Electromagnetic compatibility (EMC) - Part 2-12: Environment - Compatibility levels for low-frequency conducted disturbances and signalling in public medium-voltage power supply systems

This part of EN 61000 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. Compatibility levels are specified for electromagnetic disturbances of the types which can be expected in public medium voltage power supply systems, for guidance in: a) the limits to be set for disturbance emission into public power supply systems (including the planning levels defined in 3.1.5); b) the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances present in public power supply systems. The disturbance phenomena considered are: voltage fluctuations and flicker, harmonics up to and including order 50, inter-harmonics up to the 50th harmonic, voltage distortions at higher frequencies (above 50th harmonic), voltage dips and short supply interruptions, voltage unbalance, transient overvoltages, power frequency variation, d.c. components, mains signalling. The medium-voltage systems covered by this standard are public distribution systems supplying either: a) private installations in which equipment is connected directly or through transformers, or b) substations feeding public low-voltage distribution systems.

Compatibilité électromagnétique (CEM) - Partie 2-12: Environnement - Niveaux de compatibilité pour les perturbations conduites à basse fréquence et la transmission des signaux sur les réseaux publics d'alimentation moyenne tension

La présente partie de la EN 61000 s'applique aux perturbations conduites dans le domaine de fréquence de 0 kHz à 9 kHz, avec une extension jusqu'à 148,5 kHz pour les systèmes de transmission de signaux sur le réseau. Les niveaux de compatibilité sont donnés pour les types de perturbations électromagnétiques auxquelles on peut s'attendre sur les réseaux de distribution publics moyenne tension, dans le but d'aider à définir: a) les limites devant être établies pour les émissions perturbatrices sur les réseaux publics de distribution d'énergie (comprenant également les niveaux de planification tels que définis en 3.1.5); b) les limites d'immunité devant être établies par les comités de produit ou autres concernant les équipements soumis aux perturbations conduites par les réseaux publics de distribution d'énergie. Les phénomènes perturbateurs considérés sont: les fluctuations de tension et le flicker, les harmoniques jusque et y compris le rang 50, les interharmoniques jusqu'au rang 50, les distorsions de tension aux fréquences supérieures (au-dessus du rang 50), les creux de tension et les coupures brèves, le déséquilibre de tension, les surtensions transitoires, les variations de fréquence, les composantes continues, les systèmes de transmission de signaux sur le réseau. Les réseaux moyenne tension couverts par cette norme sont des réseaux de distribution publics alimentant: a) soit des installations privées dans lesquelles le matériel est raccordé directement ou à travers de transformateurs, b) soit des postes de transformation alimentant des réseaux de distribution publics basse tension.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for ide
