Lightning is produced by summer and spring storms spawn thunderstorm and it can cause serious damage to a building without the installation or addition of lightning protection rod to direct the entire force and energy of its destructive power to the ground. A lightning strike generally occurs when a passing cloud that is filled with negative charges of electrical power comes in contact with the positive energy of the earth.
Usefulness of lightning protection system:
The major purpose of a lightning protection rod is to protect a concrete structure from severe damage owing to lightning strikes by seizing such strikes during thunderstorm and safely passing the extremely high currents and energy force to ground. The entire system of lightning protection process includes network connection of air terminals, ground electrodes and bonding conductors and all these are especially designed to provide a low electrical impedance path to ground during potential strikes. Lightning protection system mitigates the fire hazard that lightning strikes may potentially expose the building to. A low impedance trail for the lightning current is provided by advanced lightning protection systems and hence it is meant to lessen the heating power of currents flowing through inflammable structural materials. If a lightning ray travels through water saturated materials and porous objects, there is high chance that the part of the construction may possibly explode as the water content is flared to steam by the heat produced from the current of lightning charges.
As a result of the high current levels and energy that can even be above 150,000 amps can become to dangerous for a structure and a lightning protection rod may guarantee absolute security and safety from such hazards. Lightning current divides to follow the every conductive pathway to ground and yet the divided current may result in damage. Secondary side flashes are considered as enough to set things on fire and blow away stone, brick or concrete. Nevertheless, the possibility of injury of the occupants within a building or structure is also of major concern and all these can only be avoided with the benefits of fundamental lightning protection system that has been in use for well more than a century.
Materials used:
The underground link to the lightning protection rod is manufactured with copper wire. The underground connection should never be made with aluminum cable and the reason being aluminum wire corrodes when it is placed inside the ground. The national standard of electrical code takes the aluminum cable connection to be as a minimum of 18 inches on top of the ground joined with a bimetal splice. The ground rods should be placed transversely on either end of the structure or house and it should not exceed 100 feet in between the two ground shafts. In case this distance increases, additional ground rod must be affixed to ensure appropriate grounding. It is of absolute necessity to install lightning protection system and prevent or lessen damages to structures caused by severe lightning strikes.
