A SEMI-EMPIRICAL ICING MODEL FOR ENERGIZED CONDUCTORS

摘要：

Preliminary freezing rain experiments have been performed on fixed, heated conductor samples. The data, which complements previously reported data for analogous unheated conductor samples, provide an experimental basis for developing a refined icing model. Consequently a simple semi-empirical model is proposed that incorporates the effect of Joule heating on the weight of ice formed on an overhead power line due to a continuous freezing rain. The models predictions are checked against available field observations with promising corroborations.
