Abstract

Un dispositif d’auto ajustement (10) d’un seuil électrique de détection (Sth) d’un défaut de puissance électrique consommée d’une charge électrique, le dispositif d’auto ajustement (10) comprend une pluralité de signaux de référence (SR1, SRN) de valeur croissante selon une suite géométrique pour laquelle le produit de deux termes d’ordre équidistant aux deux extrémités de la suite équivaut à une puissance maximale de référence (Pref); un signal de consigne (Sc) représentatif du signal d’alimentation de la charge électrique; une unité d’encadrement (12) comportant une pluralité d’intervalles successif (I1, I N-1) de signaux de référence bornée successivement par les termes de la suite géométrique, un signal le signal de consigne (Sc), une pluralité de signaux de sortie binaire (SS1, SS N-1), des moyens logiques de traitement de signal (14) configurés pour assigner à un premier signal de sortie binaire (SS1) de la pluralité de signaux de sortie binaire (SS1, SSN-1) un état binaire d’appartenance du signal de consigne (Sc) à un premier intervalle (I1), au moins un interrupteur électrique (SW1) configuré pour être commandé par le premier signal de sortie binaire (SS1) et configuré pour fournir un signal de référence (SRN) de valeur d’un second terme de la suite géométrique, tel que le premier terme et le second terme soient d’ordre équidistant aux deux extrémités de la suite géométrique, le second terme étant représentatif du seuil électrique de détection (Sth).
