⚡ IEEE 80 Substation Grounding (Step Potential

IEEE 80 Substation Ground Grid Calculator

Size high-voltage utility and industrial substation ground grids under IEEE Standard 80: calculate tolerable Touch Potential (E_touch) and Step Potential (E_step) for a 50kg/70kg human body, determine minimum 4/0 AWG copper conductor length, 4"-6" crushed rock surfacing resistivity layer (3,000 Ω-m), and substation engineering margins.
