Chapter The internal lightning protection system
.
The coupled lightning current has high energy and a
high frequency.
It should ensured that all supposed protection ele-
ments cables entering the building, such as
shields, rodent guards, etc.TBS

Surge protection devices conduct the lightning current
in the incoming cables towards earth via the equipo-
tential bonding system. Due the curve with waveform
10/350 μs, this type coupling short duration., are connected the
equipotential bonding system such way to
carry lightning current
