A modular element for an electrical power distribution network of an aircraft comprises a section of a bus comprising connection points at different locations distributed along its length. The bus section comprises interconnection points making it possible to link the modular element to other modular elements arranged longitudinally in series with the modular element. Electrical conductors of the bus section are housed in an enclosure corresponding to a structural part of the aircraft. This enclosure comprises openings facing the connection points of the bus section, so as to allow the connection of at least one electrical equipment item of the aircraft to the bus section by means of a local electrical link.

Detection and location of electrical faults in a network of metal structures which can receive electric cables and allow return of current by the cables. The reflectometry-based method involves injecting a probe signal into a cable coupled to the structures and analyzing the signal reflected by the anomalies. A conductive element is provided for carrying the probe signal at a constant distance from each structure. In one aspect, an insulated conductive element is arranged inside the metal structure and is built into a longitudinal groove in a surface for receiving a longitudinal plastic holder wedged into the structure. The reflected signal from the conductive element is compared to a threshold above which an anomaly is detected, and the anomaly is located by topological correlation. The invention is useful for airplane raceways having a composite skin.
