Lightning Protection

Surge Protection – Detailed SPD Design protects electrical and electronic systems from lightning surges. Lightning can damage electrical panels, machines, computers, CCTV, and control systems. To prevent this, BLITZS designs Surge Protection Devices (SPDs) according to the international standard IEC 62305-4. After the lightning risk study, a detailed SPD design is prepared using full project information. This includes studying the main electrical panels, sub-panels, generator and UPS systems, data and communication lines, sensitive equipment, cable routing, and building layout. The building is divided into protection zones, and the correct SPD type (Type 1, Type 2, or Type 3) is selected and placed in the proper location with correct coordination, earthing, and bonding. The design also provides a clear bill of materials, exact SPD ratings, quantities, and proper documentation. This approach helps protect equipment, reduce downtime, lower repair costs, and ensure compliance with international standards, keeping electrical systems safe even during severe lightning conditions.

Soil Resistivity Testing is used to understand how well the soil can carry electrical current. This test is very important when designing a safety earthing grid and when a high level of lightning protection is required, such as LPL I or LPL II defined in IEC 62305. Different soils like dry soil, rocky soil, and wet soil have different resistance, so proper measurement is needed before designing the earthing system. At the site, special equipment is used in a method called electrical soil sounding, where probes are inserted into the ground and electrical current is passed through the soil to take readings at different depths. From these measurements, engineers determine the soil resistivity value, soil layer condition, and the best depth for earth electrodes. This data helps design an accurate earthing system, select the correct conductor size, decide the number and depth of earth pits, and ensure safe step and touch voltage limits. Proper soil testing removes guesswork and ensures safe, reliable, and standard-compliant earthing design.

Lightning Protection System (LPS) Design provides a complete and accurate protection plan for a building after the lightning risk analysis is finished. The design follows the international standard IEC 62305-3 and uses full project information such as building drawings, roof layout, structure height, electrical and mechanical systems, and site conditions. Based on this data, a detailed design is prepared that shows the exact placement of air terminals (lightning rods), the protection method used (rolling sphere, mesh, or protection angle), routing of down conductors, earthing system layout, bonding details, and coordination with surge protection. The design also includes a clear bill of materials with exact quantities, conductor sizes, detailed layout drawings, connection details, and full documentation. This helps achieve consultant and authority approval, plan installation correctly, avoid material shortages or extra costs, and ensure full compliance with standards, providing safe and reliable lightning protection for the project.

Lightning Protection Maintenance is important to keep the lightning and earthing system safe and reliable over time. Connections can become loose, corrosion may occur, and system performance can reduce if regular checks are not done. BLITZS provides yearly inspection and audit services to ensure the system is working properly. During inspection, the full lightning protection system is checked, earthing connections are inspected, earth resistance is tested using calibrated equipment, and conductors, lightning rods, bonding points, and surge protection devices are visually examined. The maintenance follows the guidance of IEC 62305 to ensure proper safety and compliance. After the inspection, a clear report with test results, photos if required, and repair recommendations is provided, along with a compliance certificate where applicable. Regular maintenance helps maintain safety, prevent unexpected failures, protect equipment, and meet insurance and safety requirements.

Protection Site Assessment is carried out to check whether an existing lightning or earthing system is working safely and correctly. BLITZS sends trained specialists to the project site to inspect the current lightning protection system, examine earthing connections and their condition, test system performance, and identify any damage, corrosion, or loose connections. The team also reviews whether the system complies with current standards such as IEC 62305. After the inspection, a clear report is provided with test results, photos if required, a list of issues found, and practical recommendations to improve the system. If necessary, upgrades are suggested so the system meets the latest safety requirements. This assessment helps improve safety, prevent system failure, meet project and insurance requirements, and extend the life of the lightning protection system.
