The prolonged 2008 winter storm of central and southern China caused extensive damage to the electrical installations and railway contact wires. As a result, the transmission provider of the state has deployed substantial efforts to mitigate the effects of future ice storms. This paper describes a research program relating with this goal. An icing and icing melting expert system has been developed to estimate the ice accretion type on wires of electrical transmission lines and the melting of this ice using the heat generated by the currents flowing in the wires, based on the meteorological parameters such as air temperature, relative humidity, wind speed, which obtained by corresponding sensors. Labview language is used in this system. DAQ card is used to acquire physical signals coming from various sensors. The signals are transmitted to computers, analyzed, and processed by the software system. Simultaneously the ice scene is monitored for security by real-time videos. This system aims to reduce the icing damage in electrical transmission lines and railway contact wires.
