Surge protection devices (SPDs) are installed at service entrances and throughout the electrical system to protect against lightning-induced surges. This creates a comprehensive protection approach that safeguards both the structure and its electrical systems.
All metallic systems within the building (plumbing, HVAC, electrical conduits) are bonded to the lightning protection system to prevent dangerous side flashes and ensure equipotential bonding throughout the structure.
Once installed, the entire system undergoes rigorous testing to verify electrical continuity, ground resistance values, and overall system integrity. Professional certification provides documentation of compliance with applicable standards.
Maintenance Requirements for Lightning Protection Systems
Lightning protection systems require regular inspection and maintenance to ensure continued effectiveness. Weather exposure, building modifications, and natural deterioration can compromise system integrity over time.
| Maintenance Task | Frequency | Purpose |
|---|---|---|
| Visual Inspection | Annually | Identify visible damage, loose connections, or corrosion |
| Continuity Testing | Every 2-3 years | Verify electrical continuity throughout the system |
| Ground Resistance Testing | Every 3-5 years | Ensure proper grounding and earth resistance values |
| Complete System Inspection | After building modifications | Verify system integrity following any structural changes |
| Post-Strike Inspection | After known lightning strikes | Assess potential damage and system performance |
Important: Documentation of all inspections and maintenance activities should be maintained throughout the life of the building. Many insurance policies require proof of regular system maintenance.
