Fluorescent fiber-optic temperature probes offer numerous advantages unmatched by other temperature sensors, including excellent electrical insulation, resistance to electromagnetic interference, resistance to chemical corrosion, and pollution-free operation. These features make fluorescent probes suitable not only for applications in biology, medicine, and other fields but also for the power industry, where they hold broad application prospects. They are primarily used for: temperature measurement of high-voltage electrical equipment and instruments, temperature measurement in generator diagnostic systems and between transformer windings, temperature measurement of high-voltage circuit breaker contacts, and temperature measurement of high-voltage cable joints.
