Abstract
The ice shedding may cause the vibration of conductors, and even threaten the safety of towers in severe cases. Based on two test models with a single span and three spans, an advanced three-dimensional motion capture system, the NDI Optotrak Certus System, is used to measure the dynamic response of the conductor following ice shedding. The influences of the ice thickness, ice-shedding ratio, ice-shedding location, and sequence are investigated. The results show that the ice-shedding velocity significantly impacts the dynamic response of conductors, and a larger ice-shedding velocity leads to a smaller jump height. The conclusions drawn from the model tests can guide the deicing and design of power lines.
