Grounding is the most fundamental technique for protection against lightning damage. You can’t stop a lightning surge but yes you can control earthing system & lightning protection system by utilizing the following techniques, 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 electricity that accumulates in an aboveground structure. Often, this prevents the attraction of lightning in the first place, As we all know that the lightning arrestors and surge protection devices are designed to protect electronic equipment by absorbing electrical surges. However, these devices are not a substitute for good grounding. They function only in conjunction with effective grounding. The grounding system is an important part of your wiring infrastructure.
