2.
The lightning current distributed through the metal
grid system and the voltage drop and the resulting
step voltage are reduced.
The earthers are typically laid apart. Additional
earth conducts are laid and connected with one an-
other grid format.

.6 Potential control
The potential control reduces the step voltage close to
rods down conductors building. the distance from the
rod down-conductor increases, the depth the
earther cable also increases (in increments 0
