On-line monitoring system on power transmission line galloping based on fiber grating sensors

Traditional sensing device of power transmission line galloping is sensitive to electro-magnetic disruptive and is short of power supply. Based on the strain effects of fiber grating, a two-dimensional acceleration-sensor was developed ,and a mathematical model for this sensor was established. An on-line monitoring system of power transmission line galloping was given using the designed sensor, which provided an accurate and reliable monitoring for the power transmission line galloping.
