Research on The Monitoring Method of Glaze Icing Based on Capacitance Effect

Icing on transmission line seriously affects the safety and stability of power system. Accurate online monitoring of icing is a prerequisite for icing prevention and mitigation. However, the harsh climate under natural icing, lack of sensor accuracy, low visibility, and low model accuracy limit its engineering applications. In contrast, the ice capacitance method measures icing capacitance value to reflect the thickness of icing, offering high sensitivity, large measurement range, less sensitivity to meteorological factors, and easy equipment integration. Thus, this paper study the monitoring method of glaze icing based on ice capacitance effect and validated its effectiveness.
