How to use fiber optic temperature measurement technology for transformer windings. Which manufacturers are using fluorescent fiber thermometers on oil immersed transformers.
Oil immersed transformers are the core equipment in power systems, playing a crucial role in the safe and reliable operation of the power system. Transformers often experience thermal faults, posing a serious threat to their safe operation. Oil temperature and winding temperature are important parameters for monitoring the operation status of transformers, among which transformer oil fills the entire interior of the transformer, playing a role in insulation and cooling, so transformer oil is also known as the “blood” of transformers.

The advantages of the intelligent control solution for oil immersed transformer windings are:

(1) Reliable, economical, and effective monitoring of the true temperature of transformer oil: This method overcomes the disadvantage of traditional thermometers that can only be installed at the top of the oil tank. The temperature probe can be arranged at the winding of the oil immersed transformer to monitor the hottest temperature of the oil.
(2) Oil tight fiber installation method: The products provided by Huaguang Tianrui have high reliability.

(3) Simple installation and operation mode: The measured oil temperature is transmitted to the fiber optic temperature transmitter through an internal electrical fiber, and the changes in oil temperature can be observed in real time. Installation and operation are relatively simple.

(4) Optoelectronic data transmission is conducive to intelligent control: the oil temperature measured by optical fibers is converted into various signals required for operation and maintenance in real time, providing convenience for intelligent monitoring of transformer performance.

This intelligent solution can achieve the measurement, control, monitoring, and protection functions of oil temperature, meeting the requirements of safety, ความน่าเชื่อถือ, and resource optimization configuration for power grid operation.
