“…Usually, stator temperature measurements are performed through conventional localized sensors such as PT100 (Platinum Thermo-resistance) or RTD (Resistance Temperature Detector). These sensors are suitable for monitoring temperature changes during standard operation (no failure), given that the temperature distribution is considered to be rather uniform [ 6 , 7 ]. On the other hand, they are not able to identify hotspots that may arise in the stator coils as a result of insulation breakdown.…”

“…Distributed temperature sensors (DTS) are important in monitoring large structures such as hydroelectric generators [1], dams [2,3], oil and gas platforms [4], subway tunnels [5], mines, and warehouses [6]. Temperature interrogation provides fundamental information about the current operating conditions of these structures, ensuring safety for employees in such locations [7].…”
