Abstract: A remote-controlled robotic equipment for tree pruning near energized power lines, which, provides a remote-controlled robotic equipment in its own, specific electromechanical structure coupled to a truck and based on a robotic arm with a stand, a positioner, a handler and an end effector-pruning tool, a collection bin and a tree branch shredder, which are all integrated, for robotized tree pruning near energized power lines, which can conveniently, safely and precisely streamline the procedures adopted in the maintenance of aerial electric power distribution networks, more specifically, tree pruning near urban electric power distribution networks, combined with full ergonomics and no exposure of operators.

Abstract: The present invention provides a three-dimensional electric field sensor for hard hats, the sensor having a stand-alone structure and constructed of polymeric and hydrophobic materials, and intended for three-dimensional measurement of the electric field in energized powerlines by its disposition on hard hats. The three-dimensional sensor of the present invention has an outer shell with a base attaching to the hard hat and a cover attaching to the base, an inner shell functioning as a capacitive sensor as well as protecting an internal electronic board, a battery and adapter assembly as a power supply, and a warning buzzer, in order to provide complete optimization procedures to alert electric utility linemen of exceedingly close proximity to medium voltage conductors in powerlines.
