This paper contains results of transient analysis of airflow around the ACSR power line cross-section in unsymmetric multi-span. The forces applied to the power line are obtained from CFD simulations, where the wind induced vibration is studied. Effe

Due to the recent situation in the neighbouring countries, where icing damaged many transmission and distribution power lines and caused financial losses, it is necessary to operate weather stations. Last icing events caught the overhead power line o
