"Transformer winding temperature control technology" is a key technology in the applicable scope of electric power engineering, and a reliable solution has long been missing. In recent years, with the continuous growth of industrial production and civil electricity demand, transformer loads have increased sharply, and the application of passive wireless temperature measurement sensors for "transformer winding temperature control technology" is imperative. For fluorescent fiber optic temperature control technology, the future market space is broad.

Fluorescent fiber optic temperature control technology is the highest-quality and most mature temperature control method in the world. Compared with traditional temperature measurement methods, distributed temperature sensing cables offer unmatched measurement accuracy and response speed, and have become the development trend of online temperature monitoring in power supply and distribution systems. Currently used temperature measurement devices in China — such as PT100, infrared, wireless networks, fiber Bragg gratings and distributed architectures — are quite common, while fluorescent fiber optic temperature sensing technology is still in the development and promotion stage. With its inherent advantages of electrical insulation, corrosion resistance, high temperature resistance, heat resistance and long service life, it is believed that it will be recognized by more and more customers!

From demonstration stations to popularization, there is still a long way to go. The temperature measurement system keeps track of the operating status of the entire line in real time, effectively detects the heating of cables under different loads, and improves cable management. It can inspect and give fire alarms in cable trenches, identify local hotspots of power cables, discover cable faults in advance and give warnings, and prevent accidents. It can protect the assets of power transmission projects: according to the temperature, the load change of the cable can be determined, the load can be reasonably allocated, the capacity of existing cables can be expanded, and the service life of cables can be extended. It can also detect external damage during cable operation.
