La présente invention permet, dans le domaine analogique et avec une source de tension sinusoïdale (6)e1(f1) et des filtres, de séparer les charges connectées en parallèle à une source de tension sinusoïdale (1) u0(f0) en charges que l'on souhaite détecter (2) Zd et en charges que l'on ne souhaite pas détecter (3) Zf, puis de déterminer, sur la base du choix préalable d'un seuil de charge acceptable, si parmi les charges que l'on souhaite détecter il y en aurait une ou plusieurs que l'on souhaiterait déconnecter, pour des raisons de consommation d'énergie ou d'importance, sans indiquer laquelle. L'invention ne requiert pas la mise en place de câbles supplémentaires et utilise comme moyen de communication la même ligne d'alimentation.
