Lightning protection systems. Lightning can easily damage a number of different building materials, and the large electrical currents can cause fires within the interior or even side flashes. Side flashes are small explosions of highly pressurized, super-heated air that occur inside the nooks and crannies of structure materials.
How surge protector works. Surge protector diverts the excess voltage and current from transient or surge into grounding wire and prevents it from flowing through the electrical and electronic equipments while at the same time allowing the normal voltage to continue along its path.
