Lightning Arresters

Product Details:

The aim of the lightning rod is to become the point of discharge of the bolt in order to achieve a controlled impact without damage. The ESE air terminal emits a continuous upward leader with time of advance to anticipate the descent of lightning and capture it before any other object within its protection area.

Product Details:

A Lightning Protection System (LPS) is designed to protect a structure or building and contents from damage caused by the intensely high voltage currents of a lightning strike (often exceeding a 1,000,000,000 Volt Amps). Lightning protection systems act like a Faraday Cage for buildings. Protecting the building and its contents from external electric fields by migrating that energy around the cage instead of through its contents. A lightning protection system offers a lightning strike a low resistance path to ground where the enormous energy is then safely dispersed. A typical lightning protection system includes lightning rods, metal conductors and ground electrodes designed to offer a low resistance path to ground and to take any high voltage currents from a lightning strike away from the structure of the building.

 

The low resistant path offered by a lightning protection system is very important as high voltage currents from a lightning strike will always take a path of least resistance to ground.

 

Without a lightning protection system structural materials of a building that share the immense loads from of lightning strike can be damaged and this damage is not always immediately apparent. If there is no low resistance path offered by a lightning protection system the high voltage current from a strike will divide to follow every conductive path to ground it can find. The extremely large voltage currents will pass through materials normally considered insulators instantly generating large amounts of heat. Due to rapid heating any porous materials like masonry can shatter violently as the air inside it expands with super sonic speed. Any materials containing moisture from humidity or rain can explode with even more volatility as its water content is flashed to steam. Other materials may suffer different forms of heat damage, become melted or even burst into flame

 

Lighting Arrester

 

A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltageterminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrester, in most cases to earth.

 

A lightning arrester may be a spark gap or may have a block of a semiconducting material such as silicon carbide or zinc oxide.

Product Details:

NEXO – FR (Franklin Rod) Conventional Lightning Protection: The NEXO FR is a passive device and it serves as a sacrificial device when the lightning strikes the device rather than the building. In a typical building, several of this Nexo FR are installed at various locations on the roof that are likely to be struck by lightning. In this way, the lightning will have a high probability of striking the Nexo FR instead of the roof. Therefore, the building is considered protected from direct lightning strikes. Conventional lightning systems are based on the protection of a structure by making an installation of horizontal or vertical air terminals which are connected to the earth with the help of down conductors. The zones of protection can be determined by the "Cone of Protection" and "Rolling Sphere" methods. The selection of the protection level allows minimizing the risk of damage to people as well as complex and sophisticated equipment and structures. The higher the efficiency of a lightning conductor is, the lower the risk of damages caused by lightning strikes will become. A protection level selection depends on the kind of building, its structure and value. Standards: IS 3029, UL-96A, NFPA 780, LPI 175, IEC 61024-1-2, API 545
