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.
It is a common misunderstanding that surge protectors will protect systems from lightning, the most familiar source of power surges. Even the most effective surge protectors can not protect equipment from the sudden increase in electrical pressure of millions of volts that lightning can supply.ow it Works. A surge protector works by channeling the extra voltage into the outlet's grounding wire, preventing it from flowing through the electronic devices while at the same time allowing the normal voltage to continue along its path.
