What is Surge Protection?

In everyday life we are reliant on a vast number of electrical devices in the home and workplace. Items such as televisions, computers, printers, microwaves, industrial machinery and more are fundamental to our way of living. 

Electronic devices are however susceptible to transient overvoltages. Also known as a surge, a transient overvoltage is when there is an increase in voltage for a short duration of time. This can be as little as a few microseconds. 

Surge protection is important as surges are capable of degrading and damaging devices, shortening their lifespan.

Surge Pro­tec­tion Devices (SP­D's)

A Surge Protection Device, or SPD has the purpose of protecting electrical devices from transient overvoltage. When there is an excess of voltage the SPD will block it out or short it to the ground. 

Transient overvoltages can be caused by lightning, electrical switching, electric motors, and more. SPDs will aid in protecting the lifespan of electrical equipment from the damages of overvoltages. 

At Southern Lightning we can provide surge protection for your business and safeguard its devices and equipment from transient overvoltages. You can increase the safety of your workplace and reduce damage to electrical devices with our surge protection services.
