A single lightning strike can cause millions in equipment damage, hours of downtime, and serious safety hazards. For critical facilities, the consequences cascade — data loss, regulatory exposure, and reputational damage compound rapidly.
Aetheric designs comprehensive lightning protection systems that integrate external protection, internal surge protection, and earthing into a unified defence strategy — tailored to your facility's risk profile and regulatory environment.
Our Approach
We go beyond prescriptive, one-size-fits-all solutions. Our engineering team evaluates the full picture to deliver protection that's technically sound and cost-effective:
- Local lightning flash density and exposure analysis
- Facility geometry, structural materials, and equipment sensitivity
- Operational criticality and downtime tolerance
- Integration of risk assessment, RSM modelling, earthing design, and surge protection coordination
The result is an integrated system — not isolated components.
Design Methodology
We employ multiple design methodologies using XGSLab's analytical platform to ensure comprehensive protection coverage:
- Rolling Sphere Method (RSM) — optimal placement of air termination systems by modelling lightning leader striking distance
- Grounding analysis — earthing system design with potential equalisation and voltage gradient control
- EMI analysis — high-frequency transient effects and fault current distribution
Designs incorporate mesh conductor systems, lightning rods, and ESE terminals as appropriate. Down conductor routing is optimised for multiple parallel fault current paths and minimised magnetic field effects.
Surge Protection Integration
Effective internal protection relies on properly coordinated SPDs throughout the electrical distribution system. We design multi-stage coordination following IEC 61643 and AS/NZS 61643:
Type 1 SPDs
Service entrance protection against direct lightning current and high-energy surges.
Type 2 SPDs
Distribution panel protection for branch circuits and connected equipment.
Type 3 SPDs
Point-of-use protection for sensitive electronic devices.
SPD selection is based on:
- Maximum discharge current ratings and voltage protection levels
- Response times and failure mode requirements
- Lead length minimisation and equipotential bonding
- Monitoring provisions for continuous protection verification
Standards Compliance
Current knowledge maintained across Oceania, ASEAN, and MENA. For critical facilities, we implement designs exceeding minimum requirements with redundant measures and lower LPL classifications.
