A grounding stick, or portable earthing device, is an insulated tool used by electricians to safely discharge residual voltage and connect de-energized high-voltage equipment to the earth, preventing electric shock during maintenance by providing a safe path for fault currents. It consists of an insulated fiberglass pole, a conductor cable (copper), line clamps, and an earth clamp, allowing workers to ground lines from a safe distance by connecting to a verified earth point, ensuring safety when working on power lines, substations, and industrial machinery.
