So with our fictitious "perfect ground" the total voltage between the pole top and ground will be, per equation (1); = (18kA)(0.00994 Ω) + (23.32 μH)(2kA/μs), or. = 169.2 + j46,640 volts. The first term of 169.2 volts is due to the DC wire resistance and is negligible compared to the inductive voltage of 46,640 volts.

The potential at the electrode is the GPR, and it decreases in a radial direction, reaching 0 V at infinity. Three typical shock situations analyzed when designing grounding grids are step, touch, and transferred voltage. Touch voltage is the most dangerous because the current passes through vital organs in the body.
