Electromagnetic Energy Harvester Design for Power Transmission Line

Abstract

Parallel to the increase in energy demand, the importance of energy transmission lines is also increasing. In order for energy transmission to be carried out correctly, transmission lines must operate uninterruptedly. Therefore, it is important to inspect and monitor the lines and to intervene immediately in case of any fault. The use of Unmanned Aerial Vehicles (UAV) for the inspection and monitoring of these lines provides advantages in terms of both safety and cost. In the study, the design and analysis of electromagnetic energy harvesters have been made in order to provide energy to UAVs. Firstly, the mathematical modeling of the core has been presented. Electromagnetic energy harvesters designed based on this model have been analyzed using the Finite Element Method (FEM). The performances of toroidal magnetic energy harvesters have been investigated according to core size, material properties, air gap and line current. According to the results obtained from the analyzes, the harvester with the best size/energy density has been determined
