⚡ IEEE 80 Substation Earthing (4/0 Bare Copper Mesh), Touch & Step Voltage Limits

Substation Ground Grid Mesh & Potential Calculator

Size high-voltage substation earthing ground grids under IEEE Std 80: calculate tolerable step and touch potential voltages (based on 50kg/70kg human body resistance and crushed surface rock layer resistivity), total 4/0 bare copper buried conductor mesh footage, ground rod spacing, ground potential rise (GPR), and substation civil bids.
