Integrated device for monitoring the deformation of an electrically insulating part

Applicant: Schneider Electric Industries Sas, France

This invention relates to an integrated device for monitoring an electrically insulating part. It is composed an optical fibre in which at least one Bragg grating is formed. The electrically insulating part is made of a composite that has a thermosetting matrix and the optical fibre has a protective sheath made from a polyamide material. The electrically insulating part, or electrically insulating enclosure - into which this device is integrated - is also described, as is a method of manufacturing the device. A portion of the optical fibre, in which at least one Bragg grating is formed, is positioned in a mould in order to obtain the electrically insulating component.
