Abstract: An electrical system having an electric circuit having a electrically insulating flat support and two electric conductors secured to the flat support, the two electric conductors being configured to have different respective electric potentials during operation of the electric circuit, the two electric conductors being separated from one another by an air insulation distance and an electrically insulating spacer extending over the flat support between the two electric conductors, and having raised elements, defining a leakage path between the two electric conductors along the spacer, where the leakage path passes via the raised elements.

Abstract: A method and a system for monitoring an electrical-energy supply network of an aircraft, wherein the electrical-energy supply network includes a plurality of protection and distribution devices connected together by at least one communication bus. According to the invention, each protection and distribution device: determines its location in the network, selects a configuration table associated with its location, receives a state table from each other protection and cutoff device, applies at least a part of the state tables to a job-related rule determining whether a contactor of the protection and cutoff device must be open or closed, controls the contactor according to the result of the job-related rule, and transfers an updated state table to each other protection and cutoff device.

Abstract: An electrical circuit of an aircraft including a power supply electrically connected to an electric charge by a conductive element, and a main electrical protection element. The electrical circuit includes a first pyrotechnic switch provided with at least one first initiator element and at least one first mechanical cut-off element, and a second pyrotechnic switch provided with at least one second initiator element and at least one second mechanical cut-off element. The first initiator element and the second initiator element are each electrically positioned in parallel with the at least one main electrical protection element.

Abstract: A hybridization system for an electric device having two terminals and two states including a closed state allowing an electric current to circulate between the two terminals and an open state blocking the circulation of the electric current between the terminals, the device being suitable for an electric arc to be generated during the switching from the closed state to the open state. The hybridization system includes: two conductors connected to the two terminals of the electric device; a timer switch having two terminals connected to the two conductors and the timer switch being suitable for being in the open state by default and, after a first predetermined duration following the triggering of the electric arc, switching to the closed state for a second predetermined duration, and an electric power supply of the timer switch, connected to the two conductors in order to derive its power only from the electric energy provided by the electric arc.
