THE SYSTEM – A Lightning Rod system must be installed by a qualified technician. The system is made up of the following components:
AIR TERMINALS – or the “lightning rods” are placed on the high points of a structure such as ridges, dormers and chimneys. A lightning rod is designed to intercept the lightning.
CONDUCTORS – cable typically made of copper, aluminum or tinned-copper and are designed to connect the lightning rods to the grounds.
GROUNDS – long rods that are connected to the main conductors and are designed to safely discharge the current below ground.
BONDS – prevent side flashes between two metallic objects. This is the connection of metal objects to the main conductor.
SURGE SUPPRESSORS– protect electronic devices from power surges. A surge is an increase in electrical current. We mount devices on the breaker panels to provide protection to electrical appliances throughout the structure.
HOW IT WORKS
A thunderstorm will result when a cold and warm air mass clash. As the charges of positive and negative energy build up preceding a storm, the result is a discharge of negative energy sent rushing to the ground. The flash is then formed from the earth to the sky. As downward strokes rush toward the earth, positive strokes from edges of buildings, chimneys, and trees strain up to meet them.
A lightning rod system is designed to provide a safe path for the charge to follow. This will eliminate the chance of fire or explosion within a structure. The system will not prevent lightning from striking nor will it attract lightning. When lightning strikes, it’s looking for the path of least resistance. When you have resistance, you have damage (such as fire). The lightning protection system is a path of low resistance to ground
