Modelling of Ice-Melting Circuit under Influence of EMF Induced by the Currents of Overhead Lines
Authors: , ,
Abstract: To prevent icing of TL (transmission lines) and GW (ground wires) during certain weather conditions the de-icing procedure is needed. The currents of operating TL influence on the de-icing process. A mathematical model was developed which makes possible the estimation of this influence. The main ice-melting diagrams are considered. The methodology of determination of induced EMF value in ice-melting loop is described. Ice-melting current curves under different conditions are compared and analyzed.
