The lightning current arrestors (SPD type type
1+2) should ideally located directly the point of
entry supply point the structure.The lightning protection equipotential bonding repres-
ents internal lightning protection the building.
Surge protection devices (SPDs) can guarantee a
voltage limitation according the insulation coordina-
tion. This ensures that
no lightning current diverted into the installation that
could disrupt electrical systems. 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.), 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). 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. These SPDs re-
duce the surge voltage very low protection level
that devices and the installation can withstand.
The equipotential bonding connects together all metal
installations (gas and water pipes, etc
