ling consisting hole and stud. The possible penetration depth the
earth rods depends various geological factors. This has the ad-
vantage that the coupling closes automatically the
time installation and creates secure connection
from both mechanical and electrical point of
view.4.1 Earth rods
Earth rods are differentiated according the type of
connection the individual earth rods, the external
diameter and the material.
Earth rods consist combinable individual rods of
length 1.

Striking tools are generally used for driving the
earth rods.
As earth rods enter soil strata of
constant moisture and temperat-
ure, this produces constant resist-
ance values
