With the arrival of summer rains, lightning strikes become more frequent, posing risks to people, buildings, and electronic equipment. It is in this context that the Lightning Protection System (LPS) becomes essential.
This system is designed to protect buildings from the dangers of electrical discharges. It captures lightning and conducts its energy safely to the ground, preventing structural damage, fires, and safety risks.
Furthermore, SPDA reduces the likelihood of lightning forming around the building, offering complete protection.

After all, is it really necessary to invest in an SPDA?
Yes, investing in a Lightning Protection System is essential to ensure the safety of people, buildings and equipment.
This is because lightning produces intense electromagnetic fields that can generate electrical surges capable of causing serious damage — such as burning electronic equipment, fires, and even structural damage to buildings.
Without one SPDA, atmospheric discharges can pass through metal structures, electrical networks and even reinforced concrete pillars, generating devastating impacts.
Furthermore, these effects are not limited to the point of impact: lightning can cause damage within a radius of up to 5 km, also affecting neighboring facilities.
The risks range from perforations and melting of conductors to the collapse of buildings, especially in companies and industries where equipment sensitivity is high.
Even more serious, lightning poses an imminent danger to human life.
In addition to being a safety issue, the installation of SPDA is mandatory in several situations, such as in tall buildings, industrial facilities and places that handle flammable materials, as required by Fire Department regulations and NR-10.
Therefore, having an SPDA is an essential investment, both to protect material assets and to preserve lives.

What is the composition of an SPDA?
The Lightning Protection System is made up of several elements that work together to ensure protection against lightning and minimize damage caused by electrical discharges.
Come with us and check out its main components.
Captors (or capture devices)
Their function is to capture atmospheric discharge, providing a safe path for electricity. Therefore, they are located at the highest point of the building—such as metal rods, mesh, or conductive tape.
Down conductors
These are conductive cables or tapes that connect the arresters to the grounding system. Their function is to conduct the electricity from the discharge to the ground in a controlled manner.
Grounding system
It's a set of rods and mesh buried in the ground. This method dissipates the energy of the discharge into the ground, protecting the building and its occupants.
What are the functions of an SPDA?
The main function of SPDA is to protect buildings, facilities and people against the direct and indirect effects of lightning.
Thus, it is designed to minimize damage caused by high currents and voltages generated during a lightning strike. Its main functions are:
- Preventive: reduces the concentration of electrical charges accumulated in the atmosphere, preventing the formation of lightning on buildings;
- Corrective: acts in the event of an atmospheric discharge, conducting electricity safely to the ground.
