    • Icing Effects on Power Lines and Anti-icing and De-icing Methods 

      Solangi, Ali Raza (Master thesis; Mastergradsoppgave, 2018-05-30)
      Icing on power lines may lead to compromise safety and reliability of electric supply network. Prolong icing can lead to power breakdown and collapse of towers. Since power transmission lines are mostly overhead and could face the direct impact of icing, and it is one of the main challenges faced by power distribution companies in cold regions. When the ice accretion crosses the safety limit then ...
