Icing on power transmission lines poses mayor problem both in Hungary and in other countries. Icing on power transmission line means an extra strain on the line and its elements. In extreme weather conditions with strong winds icing can endanger the safety of energy-supply.

This paper aims to provide a comprehensive summary on icing on power transmission lines. I presented the literature on the topic, wrote about the process of icing and the different forms of ice. I researched the possible methods to predict icing: main focus here was weather forecasting processes and models. I presented different anti-icing and de-icing techniques and compared the de-icing techniques. I also mentioned damage caused by icing and methods used for de-icing in Hungary. I analised two icing events abroad. At the end, I brought examples of future development and their possible application.

To sum up, the understanding of the process of icing and its properties helps in predicting and preventing icing, as well as with de-icing. Methods exist for prediction, prevention and de-icing, however many of these applications still awaits future testing. In my opinion severe damage from icing can be avoided with the help Dynamic Line Rating, which was mentioned in the section devoted to future applications.

My paper helps with review of icing on power lines, as well as with the usage of future methods.
