It is common to observe that companies or residential buildings end up not giving the correct priority to the maintenance of lightning protection systems (LPS). Even so, this can end up generating a series of risks, considering that this system is extremely important to guarantee the safety of everyone on the premises.
In addition to its installation, which is a process that requires care, attention must also be paid to the smallest details of its suitability, such as the location of the lightning rods. This verification will ensure greater safety for the building and a proper installation.
How is the lightning protection system (LPS) adapted?
For a lightning protection system (LPS) to be properly installed, a complete technical process must be initiated, requiring specific knowledge to ensure that no failures interrupt its progress. Ideally, a qualified professional, such as engineers specializing in LPS, should be involved in its execution.
Furthermore, the adaptation steps consist of:
Initial assessment
First and foremost, it is necessary to assess the structure that needs to be protected. From this point, it will be possible to develop a detailed analysis of the site, taking into account relevant factors such as the building's geographical location, type of building, its use, height, and also construction materials.
The main objective is to identify all lightning strike risks and determine the best approach to generate protection.
Lightning Protection System Project
The second step is based on an initial assessment of the environment. From there, the engineer will begin designing the protection system. The design will need to take into account the technical standards and specific regulations of the region where they are working, ensuring compliance with laws and overall safety.
This project should include the definition of relevant components, such as down conductors, grounding systems, and protective devices, such as surge protection devices, also known as SPDs.
Installation
Once the project is completed, the lightning protection system (LPS) components must be installed taking into account the technical specifications and applicable local standards. This should include the installation of lightning rods in strategic locations, as well as the installation of down conductors.
Other important elements that cannot be overlooked are the connections made to the grounding system and the connection of the system to the building's electrical system. During the installation period, it will be necessary to ensure the integrity of all components and their correct connection to cables and equipment.
Verification and testing
After the installation phase is complete, a series of checks and tests will be necessary to ensure that the entire procedure was carried out correctly, guaranteeing that the system is entirely safe for use. This step may involve measuring the grounding resistance.
Other procedures common to this stage include verifying the continuity of down conductors, tests focused on electrical continuity in lightning protection system components, and other assessments that will be defined by applicable technical standards.
Documentation and certification
Finally, at the end of all the previously mentioned steps, it will be necessary to document everything that has been done up to that point, including the initial assessment, the design, its installation, and also the results of the tests that were carried out in the environment after its modification.
Depending on how local standards and regulations are structured for those involved in the project, it may be necessary to obtain certification or a report attesting to the conformity of the lightning protection system with applicable standards.
Performing the lightning protection system adaptation procedure
For the lightning protection system (LPS) to fully comply with regulations, the NBR 5419/2015 standard must be fully considered at all stages of the project, as previously detailed. It is also worth noting that all Brazilian standards were extensively designed to protect the environment from electrical discharges.
Why is it necessary to carry out the adaptation procedure?
There are many reasons why the procedure for installing and adapting a lightning protection system (LPS) is important. However, the most prominent are:
- Personal securityThe main reason why lightning protection system (LPS) adaptation needs to be carried out is the need to ensure the safety of the people occupying that specific building. Lightning strikes pose many risks to human life. With an adequate LPS, the risk will be mitigated, guaranteeing a safer path for the electrical current.;
- Asset protectionIn addition to protecting people, lightning protection systems (LPS) can also be relevant for protecting property, such as equipment, buildings, and electrical systems. Lightning strikes often cause damage to structures, fires, and sensitive electronic equipment.;
- Compliance with standards and regulationsIt is very common for countries and regions to have their own technical standards regulating lightning protection systems (LPS). By adapting this type of project, it will be easier to comply with local requirements, as well as avoid potential penalties for non-compliance.;
- Requirements from insurance companies or regulatory bodies.In some cases, insurance companies may require buildings to have an adequate lightning protection system (LPS) to provide greater safety and thus offer insurance coverage. It is also possible that municipal or local authorities may require an adequate LPS to issue an operating permit.;
- Good engineering practicesFinally, it is also important to mention that the installation and adaptation of the lightning protection system (LPS) follows good engineering practices, which ensures a correct technical approach, protecting all people from lightning strikes.
In general, the lightning protection system (LPS) upgrade procedure is extremely important to ensure the safety of people, as well as the protection of property, and to remain in compliance with the regulations imposed in the country or region.
