Lightning Rod Energy Storage
A technology capable of harvesting lightning energy would need to be able to rapidly capture the high power involved in a lightning bolt. Several schemes have been proposed, but the ever-changing energy involved in each lightning bolt renders lightning power harvesting from ground-based rods impractical: too high and it will damage the storage; too low and it may not. Since the late 1980s, there have been several attempts to investigate the possibility of harvesting lightning. To facilitate the harvesting of lightning, a -induced (LIPC) could theoretically be used to influence lightning to strike in a predictable location. A high power laser could be used to form an ionized column o. • • •.

Solar PV Inverter Lightning Arrester
Grounding is the most fundamental technique for protection against lightning damage. You can't stop a lightning surge, but you can give it a direct path to ground that bypasses your valuable equipment and safely discharges the surge into the earth. An electrical path to ground will constantly discharge static. The weakest aspect of many installations is the connection to the earth itself. After all, you can't just bolt a wire to the planet! Instead, you must bury or hammer a rod of conductive, noncorrosive metal (generally copper) into the ground and make sure most of its surface area. Array wiring should use minimum lengths of wire tucked into the metal framework. Positive and negative wires should be of equal length and be run. For building wiring, the NEC requiresone side of a DC power system to be connected—or “bonded”—to ground. The AC portion of such a. In addition to extensive grounding measures, specialized surge protection devices, and (possibly) lightning rods are recommended for sites with any of the following conditions: •.
