Abstract
This article describes atmospheric icing, which is caused by the collision of supercooled minute water droplets in the atmosphere with overhead power conductor, aircraft, wind turbine and meteorological instrument. When it occurs, the degradation of the aerodynamic characteristics and/or the load increase due to the ice accretion may hamper their fundamental function, which results in a fatal accident or the collapse of the infrastructure in a worst case scenario. In the article, what influences icing exerts, how it has been studied and what measures for icing prevention have been considered are dealt with.
