Design of a New Spacer Damper for Bundle Power Transmission Lines Dynamic Behavior Monitoring Based on Fiber Bragg Grating Sensor

Article Preview

Abstract:

Galloping and ice shedding, two of significant dynamic damages to bundle conductors, are both typical three-degree-of-freedom vibrations, while few technique is studied on monitoring the torsion oscillation of the whole bundles and the sub-conductors. For the monitoring of the vertical, horizontal, and especially torsional oscillations, a novel type of spacer damper is developed, which can also detect the torsion motion of each sub-conductor, with consideration of the special configurations of bundle cables and integrated with fiber bragg grating sensors. Then, a distributed FBG network is introduced.
