Which type of grounding is recommended to prevent lighting damage?

Effective grounding is essential in lightning protection systems as it provides a low-resistance path for lightning currents to safely dissipate into the earth. By ensuring that equipment and structures are effectively grounded, the risk of lightning damage is greatly reduced. This type of grounding not only protects against direct strikes but also minimizes the risk of side-flash and electromagnetic interference that can occur during a lightning event.

Effective grounding involves a comprehensive approach, including the use of grounding electrodes, conductors, and bonding techniques to create a robust grounding system. It is designed to handle the massive electrical energy associated with lightning strikes, allowing that energy to flow safely into the ground without causing harm to structures or electrical systems.

In contrast, static grounding tends to be more focused on eliminating static charge buildup rather than the high-energy demands of lightning. Active grounding implies the use of active components to manage lightning energy, which is less common in standard lightning protection systems. Positive grounding pertains more to specific electrical systems and is not a general practice for lightning protection. Thus, effective grounding stands out as the best practice to ensure safety from lightning damage.
