We provide comprehensive engineering solutions for safe and effective earthing systems in high-voltage installations. Our services include:

Earth Grid Design & Optimization

Calculation of grid geometry, conductor sizing, and electrode placement to achieve target resistance and ensure compliance with touch and step voltage limits.

Fault Current & Potential Rise Assessment

Analysis of earth potential rise (EPR) under maximum fault conditions. Design to mitigate hazards through equipotential bonding and gradient control.

Soil Resistivity Analysis & Modeling

Development of layered soil models for accurate earth grid design.

Earthing Design

Safety Compliance & Voltage Control

Verification of touch and step voltages against IEEE 80, IEC 60479, and utility standards. Implementation of surface treatment and protective measures where required.

Integration with HV Equipment

Design of earthing connections for transformers, switchgear, cable screens, and surge arresters. Coordination with neutral earthing resistors (NER) and bonding systems.

Specialized Applications

Solutions for substations, cable sealing ends, transition joints, and offshore/onshore HVDC systems, including corrosion protection and lightning protection integration.

Our expertise ensures personnel safety, equipment protection, and system reliability for transmission and distribution networks.
