A recently granted patent (Publication Number: US11834309B2) discloses a system designed to inhibit the propagation of transient currents generated during a bond-on process through an insulated boom section. The system includes at least one inductor, such as an air core inductor or a flat conductor, which is coupled to the first end of the insulated boom section near the aerial lift platform. This setup allows the inductance of the inductor to suppress the transient currents, thereby preventing their propagation through the insulated boom section while a human worker bonds onto energized electrical equipment using a bonding wand. The system is particularly useful when the energized electrical equipment is a DC power line with voltages ranging from 10,000 to 600,000 volts.
Moreover, the patent also outlines a method for utilizing this system effectively. The method involves coupling the inductor to the insulated boom section, positioning the boom section and the human worker near the energized electrical equipment, bonding the worker onto the equipment, and utilizing the inductor to suppress transient currents during the bond-on process. Additionally, the method includes attaching an electrical link between the equipment and the aerial lift platform post-bonding. The system can accommodate various operating components within the insulated boom section, with the inductor placed in series with these components or at connection points. Furthermore, the inductor can be laminated onto the outer surface of the insulated boom section for efficient operation. Overall, this patented system and method offer a safe and effective solution for workers operating near energized electrical equipment, ensuring their protection from transient currents during bonding processes.
