Computer Model of Atmospheric Ice Accretion on Transmission Lines
Atmospheric ice accretions on transmission lines cause increased gravity and wind loads on the lines. In regions subject to icing conditions, transmission line design must take these loads into account. This report describes a numerical model for determining the accretion of ice on transmission line...
