How many earth rods does my substation grid need?

It isn't a rod count â IEEE 80 designs the grid (conductor spacing, rod placement, depth) from fault current, clearing time, and soil resistivity model, then verifies the resulting step & touch voltages against tolerable limits.

What inputs do you need?

Fault current and clearing time from your protection study, soil resistivity survey data, and the substation layout drawing.

Is this required by CEA 2023?

CEA 2023 requires substation earthing to be designed and tested to relevant standards â IEEE 80 is the internationally recognised methodology for that design and verification.

Step & Touch Potential Study — Substation Grounding Safety

A substation earth grid that measures low resistance can still be unsafe — IEEE 80 judges grounding on step and touch voltage, not a single ohmic number. LPES designs and verifies grids against the standard your safety case actually depends on.
