If a fault occurs, the grounding grid must be designed so that the actual touch and step voltages are lower than the defined by the standard. These limits depend on:

The potential difference between a person's hand (touching a grounded structure) and their feet. ieee standard 80-2013 pdf

is the maximum grid current. If the GPR is lower than the allowable touch voltage, the design is automatically safe. If it is higher, further analysis is required. If a fault occurs, the grounding grid must

: Provide a step-by-step procedure for designing grounding grids that ensure personnel safety under various fault scenarios. Technical Guidance If a fault occurs

: Define the maximum tolerable limits for potential differences that can occur between points a human might contact (e.g., touch and step voltages). Design Practical Systems
