Earth Grid Analysis

Purpose

We will determine if your substation grounding grid design is safe. We will limit touch and step potential to values below recommended limits for safe operation and protection of personnel. Using IEEE 80-2000 & IEC 60479 standards, we will:

  • Analyse earth grid model from field measurements
  • Analyse grid and earth potential
  • Analyse multiple ground systems
  • Analyse the potential rise for each grounding system including neighbouring passive grids or rods
  • Calculate maximum permissible touch and step voltages
  • Evaluate danger points in the substation and outside the substation
  • Calculate voltage, step voltage ad earth potential rise
  • Determine the size of earthing conductors
