Comes in a best conductive copper material installed at the top of the building, will neutralize the dissipated lighting with the lightning arrester and ground the fault current through lightning earthing electrode and hence protect the building and belongings from the damages.
Lightning can strike anywhere on Mother Earth! Thousands of homes and other properties are damages and destroyed by lightning each year. The damages will be very severe when there is no lightning protection system present. A guide for the protection of persons and property from hazards arising from exposure to lightning can be found in the Code of Practice for Lightning Protection (CP 33 : 1996).
A lightning protection system does not prevent lightning from striking; it provides a means for preventing damage by providing a low resistance path for the discharge of lightning energy. An air terminal is used to capture the lightning strike to a preferred point so that the discharge current can be safely directed by means of a down conductor(s) to the ground. The down conductor provides a low impedance path from the air terminal to the ground so that lightning can be safety conducted to the earth,without causing excessive large voltages.
A good earthing/grounding system can be achieved by having low resistance conductors, good quality rods, plates, earth bars and joints. Other factors such as the nature of the Mother Earth or soil, temperature and weather do have a say in determing the resistance reading at the end of the day.
