Ground connector resistance
QuickField simulation example
This is an example of the ground connector simulation, performed with QuickField software.
Plane-parallel problem of DC conduction.
Soil resistivity ρ = 10 Ohm·m
Overvoltage value U = 250 V.
Determine the resistance of the ground connector.
The electrical conductivity is inversely proportional to the resistivity of the soil σ = 1/ρ = 0.1 S/m.
We assume that some distance away from the ground connector the electric potential drops to zero.
Ground connector resistance is 250 / 23.94 = 10.4 Ohm per 1 meter of conductors length.
