How can electrical systems be protected from lightning strikes?

Electrical systems can be effectively protected from lightning strikes through the installation of surge protectors and grounding systems. Surge protectors are devices designed to absorb and redirect excess voltage caused by lightning strikes or other surges, preventing that surge from damaging electrical equipment. Grounding systems provide a safe path for the electrical discharge to travel into the ground, which is crucial during a lightning event. By ensuring that electrical systems are properly grounded, the risk of damage to the system can be significantly reduced.

Insulated wires alone do not provide comprehensive protection against lightning strikes, as they may not withstand the high voltages that a lightning strike can generate. While constructing buildings with metal roofs can play a role in deterring lightning by potentially redirecting strikes, it does not provide direct protection for the electrical systems within the building. Regular maintenance of power lines, while important for overall system reliability, does not specifically address the hazards posed by lightning. Therefore, the most effective strategy for safeguarding electrical systems from lightning is the combination of surge protectors and grounding systems.
