Abstract
In recent years, the nonnegligible corrosion of steel strand for overhead ground wires has also been detected during operation. It is of great significance to efficiently monitor the corrosion of the steel strand in real-time. In this paper, a new kind of tensile corrosion sensor based on fiber Bragg grating sensing technique was proposed and developed, which can accurately monitor the corrosion of the steel strand in real-time. The performance of the corrosion sensor was studied by an electrochemical corrosion accelerated experiment. The experimental results show that the corrosion sensor can monitor slight and moderate corrosion of the steel strand accurately and effectively, therefore the corrosion sensor is practicable and has broad application prospects in transmission line engineering.
