A WET SNOW FAILURE MODEL FOR PREDICTING SNOW SHEDDING FROM AN OVERHEAD CABLE

摘要：

In this paper, an analytical model for predicting the shedding of wet snow sleeves from overhead conductors is proposed. This model is based on a dry snow failure model and on experimental tests carried out at CIGELE laboratories. This model takes into account into the effect of the water flow within the sleeve. The results show that the time of snow shedding occurrence decreases nonlinearly as initial volume water content, air velocity and electric current intensity increase. This model can provide a fast estimation of the required Joule heat or wind to trigger snow shedding from the cable.
