Lightning can cause fire risk, equipment damage, downtime, and serious safety hazards. A complete solution combines external interception, safe conduction to earth, and internal surge protection.
Layered protection reduces lightning current risk and helps limit transient overvoltage impacts on switchboards, controls, and sensitive electronics.
Overview
Lightning protection is a common requirement for buildings and exposed facilities. High lightning current can cause severe damage to people and equipment, and may trigger fire. A good design provides a preferred strike point and controlled path to earth, supported by surge protection for internal circuits.
Lightning Equipment
A metallic capture tip is installed at the highest point of the structure and securely bonded to the earthing system via one or more down conductors, providing a preferred path to guide lightning current safely to ground and minimise damage.
Introducing the Digital Lightning Strike Counter by iEngineering. Get real-time lightning data for safety and monitoring. With advanced sensors and easy integration, stay ahead of the storm with confidence and precision.
ESE devices are lightning attractors like conventional rods, with design features intended to improve lightning-catching efficiency and extend the effective coverage area.
Services
Apart from external strike protection, equipment and company assets must be protected from transient overvoltages through coordinated SPDs and monitoring.
SPD Type 1
Installed at service entrance where lightning current may be present (typically 10/350 µs).
SPD Type 2
Main protection for LV installations—installed in switchboards to limit residual surges (typically 8/20 µs).
SPD Type 3
Supplementary protection installed close to critical equipment (final-stage protection).
Device selection depends on exposure, earthing, board arrangement, and equipment criticality. Share your SLD and layout for recommendation.
SPD Device
Protects LV boards and connected loads by limiting transient overvoltage and diverting surge current safely to earth.
Monitoring
Helps monitor lightning activity near the site to support operational decisions and safety controls.
Verification
Records strike events to support inspection, maintenance planning, and compliance-driven reporting.
Case Study

FAQ
No—systems don’t prevent lightning. They provide a preferred interception point and a controlled path to earth, reducing damage risk.
Even with external LPS, transients can enter via power/data lines. SPDs limit overvoltages and protect electronics.
