Transmission line icing is a common natural disaster in southern China with great harm to the security operation of power systems. Deicing method with high-frequency excitation has the advantages of small ice-melting current and high ice-melting efficiency, but over high operating frequency and voltage would produce electromagnetic interference to the surrounding radio communication, cause corona loss to reduce the effect of melting ice, and may increase the cost of manufacture high-frequency excitation equipment. In this paper, uniform transmission line theory is used to determine the optimum...
