Lightning protection system, a product manufactured by HENG Singapore 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.

Generally, lightning will strike the highest point of any structure or facility. A lightning protection system does not prevent lightning from striking; it provides a means for preventing damage byproviding 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.
