LPZ Zone protected external lightning protection system.3.1 Lightning protection zone concept
The lightning protection zone (LPZ) concept described
in the international standard IEC 62305-4 has proved
to practical and efficient.
Equipotential bonding created each transition
from one zone another.
• Economic, easy plan individual protection

A zone area building section which all
equipment requires the same level protection.
• Reduction malfunctions due magnetic fields.3.
• Local equipotential bonding within the protection
zone. Low partial lightning energies possible
LPZ Zone inside the building.
Benefits the lightning protection zone concept
• Minimisation the surge voltage couplings into
other cable systems arresting the energy-rich,
dangerous lightning currents directly the building
entry point and the cable’s point transition
between zones. Low surges possible

Chapter The internal lightning protection system
. The lightning protection
zone concept based the principle gradually
reducing surges safe level before they reach ter-
minals and cause damage. Metallic parts are connected to
the equipotential bonding directly. Equi-
potential bonding created each transition from
one zone another. order achieve this, a
building's entire energy network split into lightning
protection zones.2.
