1 Lightning and surge protection standards
When planning and executing lightning protection
system, necessary observe all relevant national
annexes and take account any special circum-
stances applications and the safety stipulations in
the relevant state-specific supplements.5.

Comprehensive lightning protec-
tion can only achieved through
a coordinated approach. The supple-
mentary sheets the international IEC guidelines and
harmonised European versions the various country-
specific translations often contain additional informat-
ive information specific the country question.
At its most basic, lightning and surge protection sys-
tem consists one internal and one external lightning
protection system.
Product standards
To ensure that the components can withstand the
loads which they are likely exposed applic-
ation, they must checked against the respective
product standard for external and internal lightning
protection.
A lightning and surge protection system consists of
several systems, each tailored each the others. These, turn, can categorised
into the following systems and measures:
• Air-termination systems
• Conductors
• Earthing systems
• Area shielding
• Separation distance
• Lightning protection equipotential bonding
These systems must carefully selected for the ap-
plication hand and used coordinated way
