In most places with energy transmission, data of the line can be obtained with sensors. However, in recent years, the energy requirement of sensors has been met through harvesters. The electrical power required for sensor systems can be provided through electromagnetic fields around the line, especially through the electrical power transmission line or energy-carrying cable systems. In this study, numerical analysis of the harvester with toroidal coil, which was intended to be used for sensor feeds, was performed using Ansys Maxwell. In addition, experimental studies of the harvesters with toroidal core were carried out. The results were compared with some studies in the literature. Considering line current and saturation effects, it was seen that the studied toroid models were appropriate for home sensor applications.
