Lightning Protection for Data Centres

A lightning event at a data centre doesn't just damage equipment — it threatens the availability guarantees that underpin every client contract and SLA. A single surge propagating through inadequately protected power distribution can cascade across PDUs, UPS systems, and IT loads in milliseconds.

Aetheric designs protection and earthing systems purpose-built for data centre environments — high-density electronic loads, complex power distribution, and zero-tolerance downtime.

Power Distribution Complexity

• Multi-stage distribution from utility intake through transformers, UPS, PDUs, and rack-level
• Coordinated SPDs (Type 1/2/3) at every stage to prevent cascading surge damage
• Proper energy coordination between protection stages

Telecommunications Exposure

• Fibre, copper, and wireless service entrances as surge ingress points
• Protection extending to carrier interconnects, inter-building links, and management networks

Equipotential Bonding & Signal Reference

• Low-impedance bonding network and signal reference grid for IT equipment
• Earthing verification confirming bonding meets AS/NZS 3000 requirements

Cooling & Mechanical Systems

• Rooftop HVAC and cooling tower protection via RSM analysis
• SPD protection for variable speed drives and BMS control systems

Our data centre services span the full protection lifecycle:

• Risk assessment — quantify exposure and justify protection investments against downtime costs
• LPS design — integrated external and internal protection for the complete facility
• SPD coordination — multi-stage surge protection across power and telecom distribution
• Earthing testing — bonding network and signal reference grid verification
• Site audits — independent assessment of existing protection adequacy
• RaaS — ongoing monitoring and compliance verification
