Title: (EN) Method and system for detecting and locating by reflectometry electrical faults in metal structures
Abstract: front page image
(EN)

A method for detecting and locating by reflectometry electrical faults in a metal structure includes injecting a probe signal into an electrical propagation line held at a substantially constant distance from the structure. The propagation line is connected at one end to the metal structure and at another end to a signal generator. The method further includes detecting a reflected signal in return from the injected signal. In addition, the method includes comparing the reflected signal with a reference signature of an undisrupted reflected signal.
