The form, product, and layout of the lighting rod matters, Berggren clarifies. “On the planet of lightning rod technological innovation, sharp is best,” he claims. These negatively charged ions want the smoothest feasible path to beneficial ions, so business lightning defense technological know-how functions pointy rods or radiating metal fingers. Because the electrical existing commences to movement through the lightning rod, it should be done clear of the framework on which the rod is mounted, typically through a cable terminating within a metal rod sunk into the ground to safely dissipate the electrical demand.
