Claim 0:
1. A device for detecting and locating by reflectometry an arc in an electric circuit of an aeronautical system, including:
a coupling element configured to transmit an electrical signal in the circuit and to acquire a signal passing through the circuit;
a high-pass filter having a cut-off frequency between 100 kHz and 1 GHz, the high-pass filter being configured to block the frequencies lower than the cut-off frequency;
a correlation chip able to control the coupling element and the high-pass filter, the correlation chip including a memory in which code data are stored,, wherein the code data, when executed,, Cause:
the coupling element to transmit a multi-carrier time domain reflectometry signal, MCTDR, in a line of the circuit and to acquire an electrical quantity of the reflected signal passing through the network;
the high-pass filter to filter the acquired signal so as to eliminate signals having a frequency lower than the cut-off frequency;
the correlation chip to compare the acquired signal with a first and a second threshold, the first and the second threshold being of different signs.
