  • Method for arc detection by multi-carrier reflectometry (MCTDR)
    Patent number: 11913983
    Abstract: The invention relates to a method for detecting and locating a fault by reflectometry in an electrical circuit, such a method comprising the steps of: —emitting a reflectometry signal in a line of the circuit to be studied; —acquiring an electrical variable of the reflected signal passing through the network; —filtering the acquired signal so as to eliminate signals having a frequency lower than a cutoff frequency, the cutoff frequency having a value between 100 kHz and 1 GHz; —analysing an acquired signal so as to detect a fault.
    Type: Grant
    Filed: March 16, 2020
    Date of Patent: February 27, 2024
    Assignees: SAFRAN ELECTRICAL & POWER, WIN MS
