Surge protection minimizes the risk of damage from lightning strikes, voltage and power surges by blocking or redirecting unwanted surge currents to earth. A surge protector by itself can’t guarantee your facility from a surge caused by a direct or even a nearby lightning strike but when it is paired with a lightning protection system you have the advantage of both types of protection.
How does surge protection work?
A surge protector is connected to a conductor on the line side of the equipment. The protection is also connected to ground and functions by routing energy from an over-voltage transient to ground if one occurs while isolating the conductor from the ground at normal operating voltages.
For example, by installing a surge protector between the utility lines and your electrical panel, you limit the amount of lightning surge voltage that’s able to come in the form of external wiring. From here the surge protector between the electrical panels and the connected electronics will clamp down and divert even more voltage that finds its way into the electrical system.
Different types of SPDs
Type 1: permanently connected SPDs installed between a service transformer and the service equipment over current device line and load side.
Type 2: permanently connected SPDs installed on the load side of the service equipment, including SPDs located at the branch panel and molded case SPDs.
Type 3: Point-of-use SPDs installed at a minimum conductor length from the electrical service panel to the point of use.
For maximum protection, all SPDs should only be installed by a licensed electrician familiar with the equipment and its use. In addition, Lightning Eliminators & Consultant Inc. strongly recommends that a professional engineer experienced in surge suppression technology be retained to design the protection scheme for your entire facility to ensure SPDs are properly sized and coordinated.
