The merits and demerits of common icing online monitoring methods for power supply line have been analyzed in this paper. The principle of icing monitoring based on inclination and sag method has been introduced, the affect of icing on wire stiffness has been discussed, and the wire elastic coefficient has been modificated using inclination sag method so as to calculate the weight of icing. The temperature and inclination measurement based icing online monitoring device of power supply line has been designed in this paper, and power loss reduction, data accuracy guarantee and the operation stability improvement are mainly taken into account. Through the temperature and inclination data collected by the designed device combining the video and meteorological information acquired by the base station, the power supply line icing state can be reflected timely and comprehensively, so as to ensure the safe and reliable operation of the power line.
