Abstract

The accumulation of ice/frost on overhead high voltage line (HVL) conductors may cause various problems such as broking and voltage interruptions. In this work is presented a new method to melt the ice/frost deposits from the overhead conductors, method that use the heat generated by a magnetic material wire. This method has been developed and tested on an experimental model. However, by the method using the magnetic wire, the conductor can gain sufficient heat to melt the deposits of frost/ice due to the multifunctional material used, which is characterised by low Curie temperature..
