Chapter The external lightning protection system
.
This not only offers benefits industry, e. Together, insu-
lated external lightning protection system and shield-
ing measures make contribution the guarantee of
the electromagnetic compatibility and thus the safe

The electrical installation the building should also
be protected against the impacts using suitable SPDs
(surge protection devices). The im-
pact the magnetic field can reduced within the
