Power line robotic device for overhead line inspection and maintenance
Industrial Robot, 2017Purpose This paper aims to focus on the design and testing of a robotic device for power line inspection and cleaning. The focus for this design is on simplicity and compactness with a goal to create a device for linemen and other power line workers to keep in their toolbox. Design/methodology/approach The prototype uses V-grooved wheels to grip the

Simulation of a overhead power line
2012 11th International Conference on Environment and Electrical Engineering, 2012Overhead power lines are the prevailing facilities to carry electric energy along big distances. Their proper functioning is very important for the current society due our highly electrical-dependent lifestyle. During their working, overhead power lines are under different phenomena, such as short-circuits, high-speed winds, extreme temperature ...
