DETECTING AN ELECTRIC ARC BY MEANS OF A BRAGG GRATING

Abstract: an electrical distribution route for an aircraft includes electrical cables and electrical connection interface members, and a diagnostic and detection device for diagnosing and detecting an arc fault in the electrical distribution route. the diagnostic and detection device includes an optical fiber laid along the entire distribution route and having at least one bragg grating at each connection interface member, an optical reflectometer coupled to an upstream end of the optical fiber, and an acquisition central processing unit configured to detect and locate one or more arc faults over a connection interface member by comparing the current spectral signature with the reference spectral signature of the optical fiber.
