Alain Mure-Ravaud has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Composite electrical insulator including an integrated optical fiber sensor
    Patent number: 6635828
    Abstract: The composite electrical insulator comprises an integrated optical fiber sensor placed inside the insulator. The integrated sensor can be a fault sensor constituted by an optical fiber placed on the support rod of the insulator and having optical cladding that melts at a temperature which is critical for the insulator. The integrated sensor can be a sensor for measuring stresses of mechanical or thermal origin acting on the insulator while it is in operation. It is constituted by an optical fiber having a Bragg grating implanted therein. The Bragg grating is placed on the support rod of the insulator or on a metal end-fitting of the insulator.
    Type: Grant
    Filed: May 21, 2002
    Date of Patent: October 21, 2003
    Assignee: Sediver Societe Europeenne d'Isolateurs en Verre et Composite
