摘要：
The present case study, using computer modeling technology, is to investigate the process of ice melting (de-icing) on iced ground wires due to current flowing through the ground wire. Using the AC model, the time course of heating of the given ground wire has been determined, and treating the results as input to the thermal model, the ice melting process has also been investigated by finite element thermal analysis. After comparing the elements by computer analysis to laboratory measurements, the results obtained were validated with numerical analysis.
