Abstract
The invention relates to a method for detecting events by reflectometry in an electrical line of an avionic system, said line being fed with an AC voltage at a first frequency (f1), said AC voltage being sinusoidal and composed of a succession of alternate half-periods, said method comprising a step of injecting a reflectometry signal into the network, the reflectometry signal having a second frequency (f2) higher than the first frequency (f1); wherein the injecting step is synchronized with the AC voltage, the injecting step being carried out by injecting the reflectometry signal into the network during an injection duration (ti) comprised between the start and end of a half-period (t1) of the AC feed voltage.
