Signalling on low-voltage electrical installations in the frequency range 3 kHz to 526,5 kHz - Part 1: General requirements, frequency bands and electromagnetic disturbances
This document applies to mains communicating equipment (MCE) using signals in the frequency range 3 kHz to 526,5 kHz to transmit information on low voltage electrical systems, either on the public electricity distribution network, within installations in consumers’ premises which are connected to the public electricity distribution network or within installations separated from the public electricity distribution network. NOTE 1 Installations separated from the public electricity distribution network can be operated in DC. Typical applications include MCS communication between photovoltaic panels and inverters over a DC bus in photovoltaic power generating system. Requirements specific to such installations are given in Annex G. It specifies the frequency bands allocated to the different applications as well as conducted and radiated emission limits, including conducted emission limits for the transmitter output signal voltage in the operating band. It also specifies the required measurement methods. It does not specify modulation methods, coding methods or functional features (except those for the prevention of mutual interference). Environmental requirements and tests are not included. NOTE 2 Compliance with this document does not imply permission to establish communication with locations outside the consumer’s installation or with other consumers through the public electricity distribution network where this would not otherwise be allowed. MCE can fall into one of the following categories: a) MCE implementing transmission or reception of information on low voltage electrical systems as the sole function. General requirements, frequency band allocation and emission limits applicable to such equipment are entirely covered by this document. b) MCE being equipment within the scope of other standards, integrating mains communication as one of their functions. In this case, only the general requirements, frequency band allocation and emission limits for the mains communication function of such equipment are covered by this document. Requirements for all other available functions of this equipment are covered by the relevant product standard. This document aims at contributing to EMC by limiting the mutual influence of different MCE or different mains communicating systems (MCS) operated in the same environment. In addition, this document is intended to limit interference caused by MCE signal transmission to general electrical equipment.
Signalübertragung auf elektrischen Niederspannungsnetzen im Frequenzbereich 3 kHz bis 148,5 kHz - Teil 1: Allgemeine Anforderungen, Frequenzbänder und elektromagnetische Störungen
Transmission de signaux sur les réseaux électriques basse tension dans la bande de fréquences de 3 kHz à 148,5 kHz - Partie 1: Règles générales, bandes de fréquences et perturbations électromagnétiques
Le présent document s'applique aux appareils de communication par le réseau d'alimentation (MCE, Mains Communicating Equipment) qui utilisent des signaux dans la bande de fréquences de 3 kHz à 526,5 kHz pour transmettre des informations sur les réseaux électriques basse tension, soit sur le réseau public de distribution d'électricité, soit à l'intérieur d'installations de locaux privatifs connectées au réseau public de distribution d'électricité, soit à l'intérieur d'installations séparées du réseau public de distribution d'électricité. NOTE 1 Les installations séparées du réseau public de distribution d'électricité peuvent fonctionner en courant continu. Les applications types comprennent la communication par système de communication par le réseau (MCS, Mains Communicating System) entre des panneaux photovoltaïques et des onduleurs par l'intermédiaire d'un bus en courant continu dans un système de production d'énergie photovoltaïque. Les exigences spécifiques à ces installations sont données à l'Annexe G. Le présent document spécifie les bandes de fréquences attribuées aux différentes applications ainsi que les limites d'émissions conduites et rayonnées, y compris les limites d'émissions conduites pour la tension du signal de sortie de l'émetteur dans la bande utilisée. Il spécifie également les méthodes de mesure exigées. Le présent document ne spécifie ni les méthodes de modulation, ni les méthodes de codage, ni les aspects fonctionnels (sauf s'ils concernent la prévention des perturbations mutuelles). Les exigences et les essais relatifs à l'environnement ne sont pas inclus. NOTE 2 La conformité au présent document n'implique pas l'autorisation d'établir la communication avec des sites situés à l'extérieur des installations de l'utilisateur ou avec d'autres utilisateurs par l'intermédiaire du réseau public de distribution d'électricité, si cela n'est pas autorisé par ailleurs. Les MCE peuvent être classés dans l'une des catégories suivantes: a) MCE dont la seule fonction est de mettre en œuvre l'émission ou la réception d'informations sur les réseaux électriques basse tension. Le présent document couvre intégralement les exigences générales, l'attribution des bandes de fréquences et les limites d'émissions applicables à ces appareils; b) MCE qui relèvent du domaine d'application d'autres normes et intègrent la communication sur le réseau parmi leurs fonctions. Dans ce cas, le présent document couvre uniquement les exigences générales, l'attribution des bandes de fréquences et les limites d'émissions associées à la fonction de communication sur le réseau de ces appareils. Les exigences relatives à toutes les autres fonctions disponibles de ces appareils sont couvertes par la norme de produit correspondante. Le présent document vise à contribuer à la compatibilité électromagnétique (CEM) en limitant les influences mutuelles de différents MCE ou de différents systèmes de communication par le réseau d'alimentation (MCS) qui fonctionnent dans le même environnement. De plus, le présent document est destiné à limiter les perturbations provoquées par l'émission de signaux de MCE sur le matériel électrique général.
