Earthing & Grounding Systems

A reliable grounding system is the foundation of electrical safety and stability. Proper earthing ensures that fault currents are safely discharged into the ground, minimizing shock hazards, protecting equipment, and maintaining voltage control throughout your network.

  • Ground Grid Design

Engineering effective grounding networks for substations and facilities that maintain low impedance paths for fault current dissipation.

  • Step & Touch Voltage Analysis

Evaluates voltage levels at the ground surface during fault conditions to ensure safe conditions for personnel near electrical installations.

  • Soil Resistivity Testing & Modeling

Identifies optimal grounding configurations based on soil characteristics, moisture content, and layering for maximum effectiveness.

  • Lightning Protection Integration

Seamlessly integrates grounding systems with lightning arrestors and shielding measures to safely redirect high-energy surges.

What is the difference between earthing and grounding?

While often used interchangeably, grounding typically refers to connecting a part of the electrical system to the earth for system stability, while earthing focuses on safety—protecting people and equipment from fault conditions.

Why is step and touch voltage analysis important?

It ensures that individuals working near energized equipment remain safe during faults by assessing voltage exposure between feet (step) or between hand and foot (touch) under worst-case conditions.
