Earthing and lightning protection
Earthing design studies and lightning protection design to ENA TS 41-24, EREC S34, BS EN 50522 and BS EN 62305, protecting people, plant and supply continuity.
The problem this solves
Earthing is invisible until it fails, and when it fails the consequences are safety-critical: hazardous touch and step potentials, damaged plant and protection that cannot operate as designed. Lightning protection carries the same character: rarely tested in service, unforgiving when wrong.
Project types we support
- New substations and substation extensions
- Generation, BESS and industrial installations
- Sites with elevated fault levels or difficult ground conditions
- Existing installations requiring assessment or remediation
Design, calculation and study work
- Earthing system design studies and modelling
- Soil resistivity assessment and interpretation
- Touch, step and transfer potential assessment
- Lightning protection risk assessment and design
Deliverables
- Earthing design reports and layout drawings
- Earthing calculations and compliance assessments to ENA TS 41-24, EREC S34 and BS EN 50522
- Lightning protection risk assessment and design to BS EN 62305
- Remediation recommendations for existing sites
How this reduces risk
A compliant earthing design is a life-safety control. Designing and checking it properly, against measured ground conditions and realistic fault levels, removes hazards that no operational procedure can manage around, and avoids the cost of breaking ground twice.
Why appoint Saqib Engineering
Earthing design here is integrated with the substation, cable and protection design it serves, so fault levels, layouts and bonding arrangements are consistent across the whole package rather than assessed in isolation.
Common questions
- Which standards do you design earthing and lightning protection to?
- Earthing design follows ENA TS 41-24, EREC S34 and BS EN 50522, and lightning protection follows BS EN 62305. We design against measured soil resistivity and realistic fault levels rather than generic assumptions.
- What is a touch and step potential assessment?
- It checks that the voltages a person could be exposed to during an earth fault, by touching plant or by the difference in potential across the ground, stay within the safe limits in BS EN 50522 and EREC S34. We model the earthing system to confirm compliance and design remediation where existing sites fall short.
