IEC 62488-2:2017

Power line communication systems for power utility applications - Part 2: Analogue power line carrier terminals or APLC

IEC 62488-2:2017 applies to Amplitude Modulation Single Sideband (AM-SSB) Analogue Power Line Carrier (APLC) Terminals and Systems used to transmit information over power lines (EHV/HV/MV). In particular this document covers basically baseband signals with bandwidths of 4 kHz and 2,5 kHz, or multiples thereof, corresponding to the same high frequency bandwidth/s for single or multi-channel APLC terminals.
The contents of the corrigendum of January 2020 and March 2023 have been included in this copy.

Systèmes de communication sur lignes d'énergie pour les applications des compagnies d'électricité - Partie 2 : Équipements terminaux à courants porteurs sur lignes d’énergie analogiques ou APLC

IEC 62488-2:2017 s’applique aux équipements terminaux et systèmes à courants porteurs sur lignes d’énergie analogiques (APLC) à modulation d’amplitude à bande latérale unique (AM-SSB) utilisés pour émettre des informations sur des lignes d’énergie (EHT/HT/MT).
Le présent document couvre fondamentalement les signaux de bande de base de largeur de bande 4 kHz et 2,5 kHz, ou des multiples de ces valeurs, correspondant à la même largeur de bande/s haute fréquence pour les terminaux APLC monovoie ou multivoies.
Le contenu du corrigendum de janvier 2020 et mars 2023 a été pris en considération dans cet exemplaire.
