Earthing & Lightning Studies

JMB Engineering provides earthing system design and lightning protection studies for mining, data centres, renewables and industrial facilities, ensuring personnel safety and equipment protection.

Using industry-standard software and in accordance with Australian standards, our engineers design earthing systems and lightning protection that meet regulatory requirements and perform reliably in real-world conditions.

What We Deliver

  • Earthing system design and analysis (CDEGS, SafeGrid)
  • Touch and step potential assessments
  • Lightning risk assessments (AS/NZS 1768)
  • Lightning protection system design
  • Soil resistivity testing coordination
  • Earth grid design for substations and switchyards
  • Portable earthing assessments
  • Earthing system audit and compliance review

Our earthing and lightning studies integrate with our broader power system modelling and protection engineering work, ensuring consistency across all electrical engineering deliverables. Contact JMB Engineering to discuss your earthing or lightning study.

Frequently Asked Questions

What is an earthing study?

An earthing (grounding) study analyses an installation’s earthing system to confirm it safely dissipates fault and lightning currents, keeping touch and step voltages within safe limits to protect people and equipment.

Do you provide lightning protection design?

Yes. We assess lightning risk and design protection in line with the relevant standards, coordinated with the earthing system for a complete solution.

Which sites need earthing and lightning studies?

Substations, mining installations, data centres, renewable sites and industrial facilities all benefit from verified earthing and lightning protection, particularly where high fault levels or exposed structures are involved.

How do earthing studies fit with other power system work?

Earthing studies complement fault level and protection studies — the same network data informs all three — so we can deliver them together for a coordinated, verified electrical system.
