Measurement is performed by means of distributed temperature sensing (DTS) systems, which are based on optical fiber technology. Since the measuring chain is a functional combination of optical methods, optical fiber properties, and other photonic elements together with control electronic circuits, it is necessary to nd a suitable compromise between the chosen measurement method, fi measuring range, accuracy, and resolution. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic. Current temperature measurement methods, including fiber-optic-based systems (DTS and LTS), involve high costs that limit their feasibility in medium-voltage networks, where more economically accessible alternatives are required. These fiber optic systems precisely measure the temperature profile of an asset by interpreting the.
