Earthing Compatibility Study
Scope of Our Earthing Study
Verification of Existing Earthing Systems
Including physical inspection, earth pit resistance measurement, and condition assessment.
Evaluation of Electrical Safety Parameters:
- Step & Touch Potential
- Ground Potential Rise (GPR)
- Grid Resistance
- Maximum Fault Current Handling
Design and Optimization
- Earthing grid sizing
- Electrode placement
- Selection of materials (GI, Copper, Chemical)
Technical Methodology
We adopt globally recognized standards and methods:
- IEEE-80 (2013) Guide for Substation Grounding
- IS:3043-1987 Code of Earthing Practice
- Finite Element & Analytical Techniques via ETAP
Key Deliverables
- Site survey & soil resistivity testing
- Ground grid modeling and simulation
- Risk assessment of step & touch voltage exposure
- Layout drawings & ETAP reports
- Recommendations for corrective actions
Our Recommendations
- Replace old GI pipe earthing with chemical (macronite) earthing systems for long-term stability.
- Use PVC locking pit covers for easy maintenance and mechanical durability.
- Implement a preventive maintenance schedule for cleaning and resistance monitoring.
