Analysis of fiber-optic sensors for diagnostics and monitoring of electrical equipment

The article describes the basic principles to date; one of the applications of fiber-optic technologies for measuring purposes is fiber-optic multi-sensor systems. Fiber-optic multi-sensor systems include quasi-distributed sensor networks built on the basis of fiber-optic sensors, usually based on fiber Bragg gratings. One of the main advantages of fiber Bragg gratings is the unique way of converting the measured value into a change in the wavelength of radiation passing through and/or reflected from the grating, as well as the ease of manufacturing. fiber Bragg gratings have proven themselves well and are widely used in construction, oil production, energy, aerospace engineering, etc.
