Abstract

Fiber Bragg grating (FBG) sensors are obviously attractive for many prominent advantages, such as strong antielectromagnetic interference ability, long transmission distance, and fast transmission speed. Due to these advantages, FBG sensors can be used for the health monitoring of high-voltage transmission lines. The FBG sensor can not only ensure the security of the transmission lines, but can realize real-time monitoring, which can effectively prevent serious accidents caused by rust breakage of overhead steel strand. In this paper, a new type of corrosion sensor based on FBG was developed to monitor and evaluate the degree of corrosion damage of the steel strand. To verify the performance of the FBG corrosion sensors, an electrochemical corrosion accelerated experiment was conducted on an actual steel strand. The experimental results show that the FBG corrosion sensors have a large measurement range of steel strand corrosion rate, and can monitor steel strand corrosion expansion damage in early stage effectively. The FBG corrosion sensor has practical application value in the field of electricity transmission engineering.
