Atmospheric Sensors and Energy Harvesters on Overhead Power Lines [PDF]
Sensors, 2018 We demonstrate the feasibility of using novel, small energy harvesters to power atmospheric sensors and radios simply attached to a single conductor of existing overhead power distribution lines. We demonstrate the ability to harvest the required power for operating multiple atmospheric and power-system sensors, together with short-range radios that ...

Method for Calculating of Lightning Impact Level on Overhead Transmission Line
Applied Sciences, 2021 This paper proposes a simple method for calculating the lightning impact level on overhead transmission power lines, taking into account its entire length. The method uses lightning historical data and the geographic coordinates of power line towers.

Electrical engineering & Electromechanics, 2023 Introduction. The problem of estimating power losses in grounding wires with built-in fiber optic cable for overhead power lines of voltage class 330-750 kV is relevant, while it is obvious that the amount of losses depends on the chosen brand of wire ...
