This ensures that
no lightning current diverted into the installation that
could disrupt electrical systems.
The equipotential bonding connects together all metal
installations (gas and water pipes, etc.The lightning protection equipotential bonding repres-
ents internal lightning protection the building. Surge protection
devices (SPD type must placed downstream of
the combination arrestors (SPD type 1+2) the sup-
ply point the lightning current arrestors (SPD type
1) protect the electronic devices. These SPDs re-
duce the surge voltage very low protection level
that devices and the installation can withstand.), electrical sys-
tems (power and data cables), the lightning protection
system and the earthing system, either directly via
lightning current arresters (SPD type type 1+2).
Surge protection devices (SPDs) can guarantee a
voltage limitation according the insulation coordina-
tion.

The lightning current arrestors (SPD type type
1+2) should ideally located directly the point of
entry supply point the structure. When
lightning strikes, voltage drop occurs the earthing
resistor, producing dangerous voltage differences
between the metal building components and the
power and data cables, which need prevented
