Question 1

Do lightning protection systems actively attract lightning strikes?

Accepted Answer

No, lightning protection systems do not actively attract lightning.  Instead, they are designed to intercept a lightning strike and provide a safe, low-resistance path for the electrical current to travel to the ground, thereby protecting the structure.  This prevents uncontrolled discharges that could cause significant damage.

Question 2

What is the primary function of a lightning protection system?

Accepted Answer

The primary function of a lightning protection system is to safely intercept a lightning strike and conduct its immense electrical energy to the earth.  This controlled diversion minimizes the risk of fire, structural damage, and harm to occupants or sensitive equipment within a building.  It acts as a designated pathway for the lightning current.

Question 3

Which standards govern the installation and design of lightning protection systems?

Accepted Answer

The installation and design of lightning protection systems are primarily governed by recognized industry standards, such as NFPA 780, "Standard for the Installation of Lightning Protection Systems," and UL 96A, "Standard for Installation Requirements for Lightning Protection Systems."  These standards ensure the system's effectiveness and safety by outlining specific requirements for components, placement, and grounding.  Adherence to these standards is crucial for reliable protection.
