Lightning Protection Technology Making a Lot Safer and Protected
Environment Around You
Distant or nearby, lightning strikes amount to billions of volts that is beyond a normal human or
his dwelling can withstand. They cause destruction to structure and enter the building via
conductors further reduces the service life of electrical/ electronic devices.
The Lightning discharge originating from the sky always looks for a shortest and low resistance
path to the ground further it always finds a good conductor on the ground so as to complete
the electric circuit. For this reason, it is mandatory to install a ​lightning protection system
obeying numerous obligatory standards for testing and designing.
A proper protection scheme is installed to safeguard people from electrocution and also the
buildings or structures from fire hazards. Below mentioned components are utilized to execute
the complete need as per mandatory standard IS/IEC 62305 –
1. Air terminal: sharp pointed air terminal network is employed to capture the electric
discharge and provide the conductive path to the ground. If this guarded path is not
provided, then the downstream can hit on the earth surface causing injuries and
damages. Providing a large coverage area, the ​earthing system & lightning rod is
mounted on the top of the structure to be protected and is made of Copper, Aluminium
or Copper Coated Steel etc. The effective functioning of the system depends on the
design as per the risk assessment conducted on the lightning prone area based on which
the dimensions and the material of the air terminal is determined. Moreover, in this
reliable technique air terminal is uniquely designed and positioned to provide
satisfactory protection radius.
2. Down conductor: In conjunction to the air terminal, down conductor is yet another
essential component connecting the lightning rod ​to the earth termination system. It is
also designed uniquely to withstand the over voltage spikes as it is made up of good
conductors such as copper, copper coated steel or aluminium or any such conductors
for smooth flow of fault current to ground.
3. Maintenance free earthing system​: It is the last level to any electrical network providing
a stable platform for the electric system by diverting any fault occurrences to the
conducting part of the earth crust.
As per IS/IEC 62305 & NBC 2016, the earth resistance shall be maintained as less than 10
ohm for an ideal lightning protection system.
Solid Rods Technology of low carbon high tensile steel molecularly bonded with min.
250 microns copper coating - Copper bonded steel rod complying to IEC 62561-2, IEEE
80 & IS 3043 along with Earth enhancement compound/ material of less than 0.12
ohm-meters as per standard IS 3043: 2018 together makes earthing system
maintenance free which is designed to stay for 20+ years.
4. Lightning strike counter: This is an additional accessory for analyzing fatal lightning
strikes. With the installation of this 6-digit digital display detection device, it gives you
an estimate of the number of lightning strikes hitting on the protected area. It can
automatically record valuable information i.e., each lightning strike passing through an
arrester and further analyzes it using typical surge current parameters.
All the components required for the lightning protection system shall be in compliance with
IS/IEC 62305 and are tested as per IEC 62561 series.
