Patent number: 11807384Abstract: A device includes a current difference measurement module for measuring the difference between a current flowing in a positive contact of the electrical installation and a current flowing in a negative contact of the electrical installation, a low-pass filter for filtering the differential current, a full-wave rectifier without threshold module for rectifying the filtered current and a trip module for emitting a trip command when the rectified current is greater than or equal to a predetermined threshold for a predetermined duration. The device thus makes it possible to protect a DC-voltage electrical installation in a noisy environment.Type: GrantFiled: September 29, 2021Date of Patent: November 7, 2023Assignee: Airbus Operations SASInventor: Patrick Oms

Patent number: 11726125Abstract: A main electrical cabling is subject to variations in ambient temperature over its length. A detection system for detecting a fault in the main electrical cabling able to cause a serial arc, or heating within a connection, includes a monitor electrical cabling placed alongside the main electrical cabling and a controllable current generator injecting, at the input of the monitor electrical cable, a current proportional to the current flowing through the main electrical cabling. The main and monitor sets of electrical cabling being joined at the output, an electronic circuitry measures the difference between the electrical potential at the input of the main electrical cabling and that at the input of the monitor electrical cabling and detects a fault in the main electrical cabling when the difference of the electrical potentials exceeds a predefined threshold. A fault in the main electrical cabling is detected despite the variations in temperature.Type: GrantFiled: August 30, 2021Date of Patent: August 15, 2023Assignee: Airbus Operations (S.A.S.)Inventor: Patrick Oms

Patent number: 11650239Abstract: A main electrical cabling is subject to variations in ambient temperature over its length. A detection system for detecting fault in the main electrical cabling able to cause a serial arc, or heating within a connection, includes a monitor electrical cabling placed as a return loop alongside the main electrical cabling, a monitoring device, and a return cable bringing back electrical potential at the output of the main electrical cabling to the monitoring device. The monitoring device includes a controllable current generator injecting, into the monitor electrical cable, a current dependent on current flowing through the main electrical cabling. Electronic circuitry determines a difference in voltages at inputs and outputs of the main electrical cabling and of the monitor electrical cabling, to detect a potential fault in the main electrical cabling leading to a serial arc or increase in temperature. A fault in the main electrical cabling is detected despite variations in temperature.Type: GrantFiled: August 30, 2021Date of Patent: May 16, 2023Assignee: Airbus Operations (S.A.S.)Inventor: Patrick Oms
