Protection against electric shock in low-voltage installations by the automatic disconnection of the supply must be provided in compliance with applicable national or international standards. Such regulations take into account different earthing types for installations. To realize the protection against indirect contact, the disconnection of the supply must occur within a permissible safe time. To this purpose, the determination of the actual ground-fault loop impedance (which may, or may not… CONTINUE READING
