Grounding calculation

Thanks to the grounding calculation, we can determine the resistance strength of the constructed contour, as well as its size and shape. If we delve into technical details, the grounding contour – is vertical ground rods, horizontal ground rods, and also a grounding conductor. Each ground rod is at a certain depth. Horizontal ground rods connect to vertical ground rods. The grounding contour connects to the electrical panel via the grounding conductor. In short, all elements of this system are closely connected.

Lower soil layer

Number of vertical ground rods

Topsoil layer depth, H (m)

 

Vertical ground rod length, L1 (m)

Horizontal ground rod depth, h2 (m)

Connecting strip length, L3 (m)

Vertical ground rod diameter, D (m)

Width of horizontal ground rod strip, b (m)

Specific electrical resistivity of soil

Resistance of a single vertical ground rod

Length of horizontal ground rod

Horizontal ground rod resistance:

Total resistance to the dispersion of electric current

Today you can find many different methods for calculating the grounding system. In any case, you will need to work with formulas, search for certain values, and perform numerous calculations. If you want to make your task easier, you can use our online calculator, which will accurately calculate the grounding system in two-layer soil.
