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.
