Earthing & Lightning Protection for Power Substations
Substations require an extensive earth grid to safely dissipate fault and lightning currents, control step/touch potentials, and protect equipment. GI/copper earth strips, earth electrodes, and IEC 62561 lightning protection form the grounding system compliant to IS 3043.
Why It Matters
Earthing & Lightning Protection in Power Substations
Substation earthing is engineered to control dangerous step-and-touch potentials during faults, protect personnel and equipment, and dissipate lightning. A buried earth-grid mat of interconnected conductors and electrodes spreads fault current safely. Gantry structures and equipment are bonded to the grid. The design is governed by soil resistivity and fault-current magnitude.
Finish guidance: GI or copper earth-grid mat sized to soil resistivity and fault current.
Sector Requirements
- Earth-grid mat for step/touch potential control
- High fault-current dissipation
- Lightning protection for gantries
- Soil-resistivity-based design
- Galvanized/copper conductor durability
