  • Method and system for controlling the turn-on time of a device that includes a magnetic circuit
    Patent number: 9520712
    Abstract: A method and a system for controlling the switching time of a device that includes a magnetic circuit and a conductive winding. The method includes acquiring a measurement of the magnetic field generated by the residual flux, by a sensor placed near the magnetic circuit; processing the acquired measurements to infer the residual flux in the magnetic circuit; determining, on the basis of the residual flux, the optimal time for switching on the device. The method also includes switching on a three-phase transformer. The transformer includes a primary conductive winding and a secondary conductive winding surrounded by an enclosure. A magnetic field sensor is on the magnetic circuit and/or on one outer surface of the enclosure.

  • Method for determining magnetization and the field radiated by a ferromagnetic plate
    Patent number: 7171342
    Abstract: The invention concerns the field of devices and appliances for measuring the intensity and the direction of the magnetic field emitted by a plate or a structure, such as for example a ship's hull and it particularly concerns a method for determining the magnetisation and the magnetic field radiated by a ferromagnetic plate using magnetic field sensors distributed along said plate and at known positions relative thereto.
