Development of Power Line Monitoring Technology Using Energy Harvesting

In industrial sites for power facility construction and management, if there is a safety device that indicates whether the power is on, it can prevent electric shock accidents and make electrical work and maintenance inspections safer. This paper applies a technology method that collects electromagnetic energy drifting around power lines through a receiver by applying magnetic energy harvesting technology. We develop an energy indicator that displays the energy status of power lines using a high-brightness LED with its own power source without a separate external power source such as a battery by utilizing the collected electric energy. In this paper, we examine the modeling and analysis methods of a harvesting system using magnetic energy, and derive the design results of an energy collector that satisfies the required specifications.
