⚡ IEEE 80 (Ground Potential Rise GPR = I_g x R_g, Grid Resistance <0.5Ω)

Substation Ground Potential Rise (GPR) Calculator

Calculate high-voltage electrical substation Ground Potential Rise (GPR = I_g x R_g) under IEEE 80: calculate symmetrical grid fault current split factor (S_f), determine buried mesh resistance (R_g < 0.5 ohms using Sverak / Laurent equations), evaluate transferred potential along telecommunications circuits, and substation engineering profits.
