Here's Why You May Need A Surge Protector

A modern household uses multiple electronic appliances and devices for a convenient lifestyle. However, your home's electrical equipment is susceptible to permanent damage or reduced lifespan due to a sudden and acute spike in voltage.

The anatomy of a power surge

A power surge occurs when the volume of electrical energy passing through the electrical devices goes beyond the standard 120 volts. It causes the internal wires and components of the appliances to heat up and burn out or fail prematurely.  

Faulty wiring, switching on high-powered devices, malfunctioning home electrical connection, maintenance and repair by the utility company, and lightning are common reasons behind power surges. Therefore, electricians recommend installing surge protectors to safeguard against sudden electricity peaks.

What is a surge protector?

A surge protector is an affordable appliance that protects electronic equipment from electrical power surges or voltage transients. When the voltage crosses 120V, the surge protector blocks excess current or shorts to ground voltage, protecting the home appliances from the effects of a surge in electrical power. 

We measure surges in nanoseconds, and even a minor spike can cause significant harm to the electronic devices plugged into an outlet and connected to the main power. If the surge continues and is uncontained, it forms a dangerously high voltage arch which can melt or erode the appliances and their wiring or wear out the internal components over time.

How does a surge protector work?

A surge protector detects the additional current and safely channels it to the outlet's grounding wire instead of flowing through the electrical devices. At the same time, it also allows the standard 120 V to travel along its usual path. 

Surge protectors have iron core transformers for alternate current transformation. They also have a component called MOV or metal oxide varistor to limit the voltage. MOV's consist of metal oxide and two semiconductor materials, which only allow electricity to pass through them when there is a high-level voltage. A metal oxide varistor remains inactive if the flow of electricity remains within safe limits. When there is a power surge traveling through the lines, the MOV becomes active to conduct electricity. It diverts only the additional power into the ground and away from the appliances.

Protect your appliances

Surge protectors are best used to protect expensive electronics like computers, microwaves, TVs, gaming stations, and high-end sound equipment. People should understand that surge protectors are also electronic devices and do not last forever. Always purchase a surge protector with indicator lights, warranty, UL rating, lower clamping voltage, and a faster response time. 

A power surge can occur anytime. Homeowners looking for protection from severe surges induced by lightning should consider investing in a whole-house surge protector before the main electrical panel along with in-home surge suppressors. Ensure that the home has proper grounding and wiring and all the outlets are correctly grounded to enjoy maximum benefit from surge protectors.

Hire a professional to learn how to protect your home

A local electrician can suggest a quality surge protector according to your needs to cover all the electrical equipment and reduce the possibility of an accidental electric fire.
