Surge protectors are a common device in about every household. They give you the liberty of more outlets offering different ports and some even have energy saving features. But they can do little to stop a catastrophic burst of current from a lightning strike. Small appliances and devices, when exposed to an overvoltage resulting from constant load switching up to a few amps, can be easily protected by a surge protector. However, a direct lightning strike of billion amps is other game.
There are surge arrestors also called surge protection device specially manufactured to protect electrical and electronic items from overvoltage caused due to a direct lightning strike.
It is true that the entire lighting protection system – lightning rods, cables and solid grounding provides defense against direct strike, but with the help of surge protectors.
Let us understand it this way:
The lightning rod is perched on the roof of a building providing low resistant path to the lighting current. It is connected to a down conductor which runs this current down to the nearby conductive grid buried in the ground. It is the nature of electric current to distribute itself across all paths to ground depending on the resistance on each path. The only path a lightning current gets to distribute itself with other conductors is the moment it touches the ground. This is where surge protectors come into play.
The lightning rod’s conductive grid is connected to a master switchboard. The lightning current flows from the ground into the building’s power distribution system; surge protectors arrest the current thereby discharging them to the earth again.
The other roles of surge protectors
Electronics are more critical to damage due to over voltage, short circuit or a damaged switchboard. Protect them permanently via surge protectors.
Lightning eliminators offer an array of surge protectors along with complete solutions to protect you and your property from lightning strike.
You can choose a surge protector and its services according to your needs. For example, Facility Guard is designed for Industrial and commercial use whereas their DC Surge Protectors protects against fast-rising transients and slower, high-energy impulses.
