Abstract

La présente invention concerne un système (128) comportant : - un dispositif de couplage (210) ; - un dispositif de traitement de données (218) conçu pour : fournir un signal d’excitation (SE) pour qu’un signal interne (Φ) apparaisse dans le dispositif de couplage (210), ce signal interne (Φ) présentant une déformation résultant du courant à mesurer (I0), obtenir un signal de mesure (Sm) d’une grandeur (Vm) sensible à la déformation du signal interne (Φ), fournir un signal de compensation (Sc) pour annuler la déformation, et évaluer le courant à mesurer (I0) à partir du signal de compensation (Sc). Le dispositif de traitement de données (218) est en outre conçu pour coder des données à transmettre (Tx) en un signal codé (Sd) présent dans le signal d’excitation (SE) afin que le signal se propageant sur la ligne de transmission (118) inclut les données (Tx) à transmettre.
