Introduction of Lightning Arrester
Lightning arrester is a protective device used for protection against lightning strike it is a metal rod which is of copper, steel or aluminium installed on top of the building structure and connected to the earth
by means of down conductor.
Lightning arresters are used for protecting the
building structure from direct lightning this building structure may be
Residential Building, Commercial Building, school offices etc. lightning strike is common during rainy season it's a natural phenomenon and act of nature but during lightning strike the cloud generate heavy static energy.
Lightning Strike is a Powerful Electric Discharge This energy is nothing but simple electrical energy which has been developed between the ground and the sky during this process ground has been positively charged and sky has been negatively charged hence the negatively charged energy travels towards the positively charged energy towards the ground and strikes at the tallest point in the ground which can be a tallest tower an isolated tallest trees any object which is tall in the surrounding area are on high risk of at the time of strike
Protection from this unpredicted nature calamities lightning arrester is used which are always installed on the top of the building so that when the Lightning Strikes it will strike on lightning arrester and the strike which hits the Lightning arrester can easily be discharged to ground without any damage to the structure.
Lightning Arrester Working Principle.
As explained above Lightning Strike is nothing but a powerful electrical discharge that travels to the ground during lightning strike This electrical discharge
has power of rating till 100KA (Kilo amps) which can damage a structure.
Step By step Understanding for working principle of Lightning Arrester
When Lightning Strike it strikes on lightning Rods installed on the building.
Lightning Rods are connected to the Ground with Down take conductors
from Lightning Rod to earthing pit at Ground.
Down take Conductors Discharge the heavy current which flows during
the lightning strike safely to the ground.
Structure becomes safe and unaffected as the strike has been interrupted
by lightning arrester and discharged to the ground.
Types of Lightning Arrester
Lightning arrester are two types widely used for Commercial
Residential & Factories
- Conventional lightning arrester.
- Early streamer emission (ESE) lightning arrester.
Conventional lightning arrester.
Conventional lightning arrester are simple metal rod made up of mild steel, aluminium or copper This rod is normally 1 meter to 1.2-meter height
Protection radius of conventional Lightning arrester is 10 -12 meter it can be a spike type or pointed solid rod figure as shown below.
Spike Type copper Lightning arrester with metal Base
Copper Bonded Lighting Arrester with PVC Bace
copper bonded or pure copper Pointed Rod
Early Streamer ESE Lightning Arrester.
Early Streamer ESE lightning arrester are advanced lightning arrester
which operates on the principle of ionization System which covers greater Protection Radius as compared to conventional earthing.
The protection Radius of Early Streamer is 71Mtr/84mtr/95/107mtr selection to be done as per the area to be Protected.
Working Principle of Early Streamer lightning arrester.
Early Streamer Lightning arrester has an Ion generator inside.
which is charged before lightning strike at the time of lightning strike the atmosphere become charged with electrostatic field.
Due to this electrostatic field effect inside the atmosphere Eon generator gets charged with electrostatic field
This charged electrostatic field from eon generator moves upward from ESE towards the atmosphere
upward lead charge attracts the lightning strike which creates a good conductive path.
the strike is intercepted, and the captured energy is safely discharged inside the ground
By means of down conductor which is connected from lightning arrester to earthing Pit
What is the Importance of Lightning Arrester.
Lightning arrester is necessity to protect Building structures from lightning strike for Residential,comercial, and industrial buildings
Lightning strike damages the structure of building electronic equipment's it may also be fatal to human being when it comes to direct strike
In factories when lightning strike it damages the Machine electronic parts and due to which unnecessary Break down accurs
in residential Buildings it can damage household equipment's
in commercial Premises it can damage computers and other electronic equipment's
to avoid all these unwanted damages, it is advisable to install lightning arrester.
Advantages of lightning arrester
Protects your structure
Protects your equipment
Personal Protection
to install a Lightning arrester the cost is only one Time with no maintenance and the life of Lightning arrester is 10 to 15 years
it is a buy back price which doesn't compromise for your safety once installed.
Installation of Lightning Arrester.
Lightning arrester installation usually takes 2 to 3 days further depends upon the site situations and other parameters
such as the structure height lightning arrester to be installed on foundation and other consideration
key factors to be checked before Lightning arrester installation.
Structure Survey
Lighting arrester installation space
Down conductor Routing selection is important as it should be apart from any conductive object/material.
Proper working Platform should be there for installation of down conductor.
Earthing Location to be checked for connectivity of Down conductor.
Lightning Arrester Material List
