Abstract: An integrated device for monitoring an electrically insulating part, the device having an optic fiber that includes at least one Bragg grating, the electrically insulating part being a composite material with a thermosetting matrix, and the optic fiber including a polyimide mechanical protection sleeve made. The device is integrated into an electrically insulating part or an electrically insulating enclosure. The invention also includes a method for manufacturing the device including positioning in a mold part of an optic fiber that includes at least one Bragg grating, and molding of the electrically insulating part.

Abstract: An integrated device for monitoring an electrically insulating part comprising an optic fiber in which at least one Bragg grating is formed, the electrically insulating part being made from a composite material with a thermosetting matrix, and the optic fiber comprising a mechanical protection sleeve made from polyimide material. An electrically insulating part or an electrically insulating enclosure in which the foregoing device is integrated. A method for manufacturing the foregoing device comprising positioning of a part of an optic fiber in which at least one Bragg grating is formed in a mold to form the electrically insulating part, and molding of the electrically insulating part.
