Mat Earthing System
Engineered Earth Mats (Grid Earthing) designed to minimize Step & Touch Potential in Substations and Industrial Plants. Compliant with IEEE 80 standards.
System Overview
Mat Earthing involves creating a horizontal mesh of conductors (MS Flat, GI Flat, or Copper) buried underground. This mesh connects all equipment structures to a single grounding system, creating an Isopotential Plane.
This is critical for high-voltage substations (33kV, 66kV, 220kV+). In case of a fault, the mat ensures that the voltage difference between a person's feet (Step Potential) or between their hand and feet (Touch Potential) remains within safe limits.
Why is Mat Earthing Critical?
Human Safety
Reduces Step & Touch Voltage
Fault Handling
Dissipates massive currents
Uniform Potential
Prevents equipment damage
Custom Design
Grid size as per soil test
