Lightning Protection System

Lightning Protection System Design and
Products The first step in lightning protection
system design is Risk Assessment. Axis has used
the guidelines of IEC 62305 Part 2 to design a
Risk Assessment Software that allows you to
assess the risks and determine the Class of
Lightning Protection System (LPS) for your
structure. This software uses parameters unique
to your structure to help you determine the best
and most efficient protection system. In fact,
our software also allows you to calculate the
Seperation Distance for your Lightning Arresters,
Length of Earth Rods, Type of SPD, and more!

Protection System Design Software. Based on your
Risk Assessment, you can now design the external
and internal protection systems for your
building. The External protection system would
include an Air Termination, Down Conductor and
an Earth Termination System. For internal
protection, one would use surge protection
devices and equipotential bonding. Air Termination
2
The positions of the Air Termination can be
decided based on the rolling sphere method, the
protective angle method and the mesh method. The
rolling sphere method can even be used to define
the zones of protection for structures with
complex geometry. The radius for the sphere is
determined directly from the Class of LPS. The
Protective Angle method is used for simple
structures but only up to a certain height as
determined by the class of LPS. The Mesh Method
is best used for flat surfaces where the air
termination conductors are to be placed at the
roof edges and where no other metallic structure
will be above the air termination system. Axis
Air Termination Rods, made from high grade
electrolytic Copper, provide the highest
conductivity that allows the flow of lightning
strikes without any damage to the structure or
equipment. Early Streamer Emission (ESE)
Lightning Arrester The ESE Lightning Arrester,
also known as Active Lightning Arrester, provide
an enhanced Radius of Protection, reducing the
number of Lightning Arresters and down
conductors needed for your building or solar
project while still providing complete
protection. Down Conductors Down conductors,
connected to the Air termination system with
suitable Axis products, should take the most
direct route down the structure, with spacing
between each one defined by the Class of
LPS.Axis Copper Clad Steel Down Conductors are
specially developed to offer the high mechanical
strength of steel and the current carrying
capacity of Copper.Since IEC 62305 also allows
the use of rebars inside concrete structures as
down conductors under certain conditions, Axis
offers specially designed products to use this
technology effectively. Earth Termination An
Earth Electrode should provide low electrical
resistance with the earth to allow for the
dissipation of currents. It should also be
resistant to corrosion because it will be buried
underground for a long period of time. Worldwide,
one of the most popular Earth Electrodes are
copper bonded earth rods, which comply with IEC
62561 Part 2. Since electricity is a surface
phenomenon, the copper layer allows for a
conductive path while the inner core of high
strength steel provides the strength required
for driving the rod inside the ground. Axis
Copper Bonded Earth Rods have been are approved
by Utilities across the world and continue to be
popular due to their consistently high
quality. Internal LPS

The two major components of internal LPS are
Equipotential bonding and surge protection
devices (SPDs). The purpose of Equipotential
Bonding equipment is to bring all the metallic
parts and equipment in a structure to the same
Voltage Potential, to avoid hazards to human
life or other damage. SPDs protect electronic
devices by breaking the circuit in case of an
equipment or system fault. Conclusion Since 1994,
Axis has continued to manufacture and supply high
quality lightning protection and earthing
equipment internationally. We have a proven track
record of high quality protection. Our customers
include Utilities, Government Organizations and
Private Projects across the globe. To learn more
