Les processus dans les grands systèmes énergétiques présentent une grande variabilité en raison de la nature stochastique de la production et de l’utilisation de l’électricité. Cependant, le contrôle du transfert d'énergie vise à atteindre un fonctionnement en régime permanent, qui est principalement décrit par des signaux entièrement identifiables par un ensemble fini de paramètres. Une partie du système de contrôle est le processus d'information fourni par le biais de mesures. Dans cet article, nous analysons l'impact du système de mesure déployé pour rapporter le paramètre RMS du signal de tension sur la qualité de l'information dans les réseaux de distribution BT. Le fonctionnement de tels réseaux est très stochastique et les modèles choisis basés sur la moyenne ne sont pas toujours appropriés ; par conséquent, nous proposons d'appliquer une métrique statistique, c'est-à-dire le coefficient de variation de l'écart quadratique moyen CV (RMSD).
