In the recent months the AEI team has put in place advanced lightning protection systems for a number of large companies across Australia. Lightning protection is a topic that is not often talked about within the electrical industry. However these systems can have a major impact on economic and safety implications for commercial enterprises Australia wide.

 

What is a Lightning Protection System?

Lightning is a charge of electricity that travels from a thundercloud. This ‘charge’ can produce a very strong current that has the potential to cause damage to any electrical component that it comes into contact with.

A lightning protections system (LPS) transfers this lightning current safely to the ground. The system provides a better, low resistance path for the lightning to travel and directs its potentially harmful current from its intercept location to its ground destination. It does so without allowing the current to travel through a buildings electrical or plumbing structure, reducing overall risk.

How Does a Lightning Protection System Work?

An external LPS consists of an air termination system, a down conductor and an earth termination system. This system provides a low resistance path that dissipates the high current and directs it into the soil. The down conductor securely limits the voltage imposed by the lightning without raising the potential of the down conductor to have high values and to produce sparks.

Overall the highest point of a building or facility is the most vulnerable to a direct lightning strike. Lightning rods, air terminals, or dynaspheres are installed at these danger points in order to offer one preferred point in which to capture the strike and then safely conduct its discharged energy down to the ground. Dynaspheres in particular offer a computer aided design and enhanced area of protection at a facilities weakest point in order to deliver optimal protection.

Why is it Important to Protect Your Business from Lightning?

The safety and economic implications of a lightning strike can be extremely destructive. Wherever there is the possibility of a direct lightning strike there is potential to damage valuable equipment, facilities and the people located within these areas. Lightning is transient in nature so it has the ability to produce wild rise times and in some cases large magnitude currents. If a LPS is not in place to limit the voltage imposed by a lightning strike and direct it safely to the ground, the implications can be disastrous.
