Janakiraman senior manager product development obo bettermann india pvt ltd explains the design guidelines. Lightning protection system design. Know how to design earth termination system know how to write specifications for the designed lps. Like many other engineering systems lightning protection is not necessarily a design preference but the need for a lightning protection system is determined by the requirements of nfpa 70 and nfpa 780 a lightning risk assessment and oftentimes the facility s insurance carrier.

The lightning protection system lps comprises of air termination down conduction earthing equipotential bonding surge protection system and fail safe scheme during lightning condition. During thunderstorms too high volume of energy is instantaneously released which is more common in nature. Historical understanding of lightning from statements made by ben franklin. The standards define an effective lightning protection system as a set of equipment and devices to capture never to attract lightning and conduct it safely to ground.

The value received begins with proper design continues through quality installation practices and must include inspection and certification. Apart from ensuring protection to people and services connected to the structure lps ensures protection against direct and indirect. The need for greater capability in. Desigr ers thought that protection was not necessary in many cases because the antenna mast was relatively short 10 meters or less.

Device for picking up lightning. Lightning protection systems have a remarkable record of protecting against physical danger to people structural damage to buildings and failure of internal systems and equipment. All wind turbines need to have a lightning protection system lps. Considerable material is used to make up lightning protection systems so it is prudent to consider carefully where an air terminal will provide the greatest protection.

All lightning protection systems must follow these regulations. On completion of this course the target person will be able to. The lightning protection level lpl is generally recommended to be lpl1 which is the highest level of protection. A risk assessment based on actual lightning exposure design of the air termination network and down conductors di fth tht i ti t k d thdesign of the earth termination network and earth electrodes.

History of lightning protection system design in tactical sstems many older communication systems do not have lightning protection incorporated into their design. Lightning protection system lps design comprising. Design engineers new graduate engineers under graduate engineering students.
