Lightning Protection – Design, Supply, Installation and Maintenance |
A lightning strike to an unprotected home can be catastrophic.Fair weather is something we all appreciate but inclement weather
creates and has created havoc in our surroundings. Lives have been lost and businesses have been suffered
losses due to Lightning Strikes in various parts of the country and
in various installations.A single bolt of lightning can carry over 30 million volts of electricity, 35000 Ampere. (35KA) Lightning can rip through roofs, explode brick, concrete and ignite fires. Lost lives are assets, which cannot be replaced. Lost data may take months or never be recovered.
Replacing Burnt out expensive equipment may cost millions of rupees that our nation cannot afford! 4 Step Approach to Total Protection
Protection of Direct Lightning - Lighting Active AerialsLighting Active Aerials (ESE/CAT/Franklin Rod) could be installed on top of buildings, and connected to an electric earth by the use of solid copper conductors, so as to provide a correct path for the lightning strike to discharge to ground. The type of the Lighting Active Aerials would depend on the size of the buildings, and on the required protection levels |
Protection of Power Lines ; Data LinesPower and communication cables entering the building either from outside the premises, or from the roof, or from the open areas within the premises, could be loaded with electric surges due to the lightning strikes: Surge Protectors could be installed on such cables leading to sensitive equipment to clean it from the electric surges, to a level acceptable by those sensitive equipment.
Earthing SystemsA dedicated lightning earth is critical to the integrity of any lightning protection system. For optimum performance of a lightning protection system it is essential that a low impedance earth be provided to allow for the safe and efficient dissipation of the lightning energy into the groundmass.
