Advantages of Fiber Bragg Grating Temperature Sensors in Temperature Measurement of Power Systems

The IF-FBG700 fiber optic grating series is a temperature measurement sensor model independently developed and produced by FJINNO. The fiber optic grating can be customized according to customer requirements, with stable performance, making it a filter. It can also provide distributed systems and good service. The manufacturer and supplier use international advanced technology to focus on researching and solving the processing of special gratings, with high stability! We have received high praise on various fiber grating products such as apodized fiber Bragg gratings, chirped fiber Bragg gratings, phase shifted fiber Bragg gratings, etc! Fiber Bragg Grating Temperature Sensors and Fiber Bragg Grating Demodulators have received high praise, and are ranked among domestic companies in terms of fiber Bragg grating sensor prices, professional research and development, fiber Bragg grating analyzers, a full range of fiber optic sensing, sales, and distributed fiber optic sensing production brands

The IF-FBG700 fiber optic grating temperature sensor is directly installed at the electrical joints of high-voltage electrical equipment such as substations, transformers, transformers, capacitors, etc. It utilizes the changes in the center wavelength of reflected light from various sensors connected in series or parallel along the fiber optic for online temperature monitoring. The sensor part does not require power supply and is not affected by electromagnetic interference. Fiber Bragg grating, as one of the most promising passive optical devices, has been widely used in the field of fiber optic sensing due to its superior characteristics such as anti electromagnetic interference, corrosion resistance, low fusion loss, high sensitivity, small size, and easy distributed measurement. The use of fiber optic gratings for high-temperature safety monitoring has broad application prospects, and the practical research of temperature resistant sensing systems based on fiber optic gratings has always been a hot topic of concern for scholars at home and abroad; Fiber optic grating acoustic emission sensing technology is a new detection technology that combines the advantages of fiber optic grating sensing technology and acoustic emission detection technology. It has shown good development momentum in the field of structural health monitoring.

With the rise and rapid development of various fields of fiber optics, there is an increasing demand for new types of fiber optic devices with higher performance and lower costs, which continuously promotes the development and innovation of fiber optic devices. In this context, fiber Bragg gratings, as a new type of fiber optic device, have received great attention and made continuous progress due to their flexible and variable structural characteristics, as well as good and stable frequency selection characteristics. Fiber Bragg grating is a refractive index distribution formed in optical fibers through methods such as illumination and candle engraving. When light is transmitted in a fiber with this refractive index distribution, it undergoes symmetry, thereby achieving control over phenomena such as reflection and loss during light transmission in the fiber. By utilizing this characteristic, fiber Bragg gratings have been greatly developed and applied in fields such as optical information processing, fiber optic communication, and fiber optic sensing.
