Earthing & Grounding Studies
Safe, economical earthing systems for substations, plants & large sites.
What we deliver
- Soil model development: Wenner/Schlumberger data processing, multi-layer soil fitting.
- Grid design & optimization: Mesh/rod layout, conductor sizing, fault current splits.
- Touch/step voltage assessment: Compliance against IEEE/IEC/EN safety limits.
- Surface layers & mitigation: Crushed rock, gradient control, potential grading.
- Interface studies: Transfer potentials to bonded/adjacent sites, pipelines & rails.
Applicable standards
Typical references include IEEE Std 80 / 665, IEC/EN 50522, IEC 60479 and local utility guidelines.
Lightning & Surge Protection
Assess risk, define protection levels and specify coordinated surge measures.
We model direct/indirect strikes, coupling paths and surge exposure to size down-conductors, air-termination systems and SPDs that work as a coordinated set.
Scope
- Lightning risk assessment & LPS class selection (IEC 62305 methodology).
- Rolling-sphere & protective angle verification for air-termination coverage.
- Down-conductor bonding, equipotentialization and earthing integration.
- Surge protective device (SPD) selection & coordination for LV/MV/I&C.
- Transient studies for sensitive loads and control systems.
EMI / Interference
Predict and mitigate interference into rails, pipelines, telecoms and controls.
Study areas
- Inductive & conductive coupling: HV lines → third-party utilities.
- Cathodic protection interactions: Co-located pipelines and earthing systems.
- Rail traction effects: Return current paths, touch/step on platforms & fences.
- Telecoms & signalling immunity: Field levels vs equipment limits.
- Mitigations: Separation, bonding, cable shields, decouplers, gradient control mats.
Data & workflow
- Intake: single-line, site layout, soil/boring logs, fault levels, CP/rail data if applicable.
- Model build in XGSLab with quality checks and sensitivity runs.
- Review workshop to agree mitigations before finalization.
Deliverables
- Engineering report with assumptions, results, compliance checks and recommendations.
- XGSLab project files, soil model fits, and result plots (touch/step, potentials, fields).
- Construction drawings/details for grid layout, bonds, SPDs and mitigation hardware.
