    • There is provided an integration of the leakage current functions of an RCD and the voltage sensing functions of other prior art protection devices. By integrating the two capabilities into one decision making system/algorithm, and considering the circuits performance in terms of leakage current as it correlated with elevated protective earth voltages (and vice versa), an embodiment is created which is able to "look into" a protected electrical system and make much more precise and discerning decisions on electrical status and probability of unsafe events. The resultant technology attends to the outstanding issues with the prior art technologies as they stand, and provides a protection solution that covers the entire range of electrical power wiring configurations and the practical complexities of modern electrical works.

    • L'invention concerne une interface permettant de couper l'alimentation électrique pour tout courant de défaut Id ≤ 300 milliampères tel que : Id≥ IPE + k.Ih où IPE représente le courant revenant ô la source d'alimentation par le conducteur de protection reliant les masses ô la terre et Ih ( ≤ 10 ou 30 milliampères) représente le courant revenant ô la source d'alimentation autrement que par le conducteur de protection ou par un conducteur actif. Le courant Ih est donc susceptible de traverser une personne. Ainsi, elle assure la protection des personnes et des biens contre les défauts d'isolement ô la masse et contre certains contacts directs indépendamment de la terre des masses et des conditions d'influences externes. Elle assure aussi la protection des personnes en cas de dysfonctionnement de la protection d'un voisinage utilisant la même terre en cas de défaut.
