SIST EN 62488-1:2013

Power line communication systems for power utility applications - Part 1: Planning of analogue and digital power line carrier systems operating over EHV/HV/MV electricity grids

The object of these standards is to establish the planning of the services and performance parameters for the operational requirements to transmit and receive data efficiently over Power Networks.

Systeme zur Kommunikation über Hochspannungsleitungen für Anwendungen der elektrischen Energieversorgung - Teil 1: Planung von Systemen zur analogen und digitalen Nachrichtenübertragung über Hochspannungsleitungen

Systèmes de communication sur lignes d'énergie pour les applications des compagnies d'électricité - Partie 1: Conception des systèmes à courants porteurs de lignes d'énergie analogiques et numériques fonctionnant sur des réseaux d'électricité EHT/HT/MT

La CEI 62488-1:2012 s'applique à la conception des systèmes à courants porteurs de lignes d'énergie analogiques et numériques fonctionnant sur des réseaux d'électricité EHT/HT/MT. Elle a pour objet de définir la conception des services et des paramètres de performance relatifs aux exigences opérationnelles en matière d'émission et de réception efficace des données sur les réseaux électriques. Le support de transmission utilisé par les différentes compagnies d'électricité comprend des systèmes analogiques et numériques accompagnés de services de communication plus courants, tels que les autorités de télécommunications nationales, les liaisons radio, les réseaux à fibres optiques et les réseaux par satellite. Grâce aux développements des infrastructures de communication au cours des deux dernières décennies et à la capacité des dispositifs connectés au réseau de communication électriques à communiquer en interne et en externe, il existe une grande variété d'architectures utilisables dans le réseau de distribution d'électricité pour fournir des communications sans raccord efficaces.

Sistemi komunikacij po elektroenergetskih vodih za elektroenergetska podjetja - 1. del: Načrtovanje analognih in digitalnih nosilnih frekvenc na elektroenergetskih vodih, ki obratujejo na najvišjenapetostnih (EHV), visokonapetostnih (HV) in srednjenapetostnih (MV) električnih omrežjih (IEC 62488-1:2012)

Cilj teh standardov je določiti načrtovanje uporabe in parametrov uspešnosti za obratovalne zahteve za učinkovito oddajanje in prejemanje podatkov prek električnih omrežij.
