Design of a Novel Electromagnetic Energy Harvester With Dual Core for Deicing Device of Transmission Lines

An electromagnetic energy harvester (EMEH) is proposed in this paper which is designed considering the power requirement of an ice removing device used to remove the ice and snow from power transmission lines. This paper addresses the influence of the material characteristic of the magnetic core to achieve the required power. Three different core materials, namely, silicon (Si) steel, nickel (Ni) steel, and nano crystalline HTX-012 core are used to design single and dual core models with three different airgaps using 3-D finite-element analysis and are compared in terms of the induced voltage, saturation flux density, relative permeability, and core losses. Comparison shows that the EMEH with Si-HTX-012 core and stepped airgap can produce the highest induced voltage.
