Fiber-optical sensor for control of parameters overhead power lines

The article presents the physical properties and principle of operation of a fiber-optic sensor based on a Bragg grating and analyzes its indicators. Schemes of a fiber-optic sensor are proposed depending on the purpose of the optical fiber in the sensor. The expediency of using a distributed fiber-optic sensor to control the operational and structural parameters of overhead power lines is substantiated by analyzing the sensitivity indicators of the Breggir grid to the temperature ranges of the wires and mechanical force, as well as the need to take into account during the design of equipping the lines with monitoring systems with a fiber-optic sensor.
