Icing of the transmission line in the winter is an ongoing problem; it could result in widespread power outages and a large number of losses in repairing.While there are many methods of melting ice in the world

but the results were poor.Using the high-frequency and high-voltage excitation to melt ice is a new method which emerged in recent years.Under the high-frequency excitation

ice will be transformed into a loss dielectric so that it could cause self-heating.The skin-effect will occurred in the conductor

which will cause the Joule heat emerged in the interface of conductor and ice.Through adjusting the integrated heat of these two effects by adjusting the frequency

only a stable integrated heat can achieve a good de-icing result.Finally

By the ANSYS simulation

It concludes that melt ice with the high frequency and high voltage excitation is not only a feasible method but only a more efficient method.
