A quick guide to surge protectors, how they work, and why they help protect everyday electronics.
Benefits of Using a Surge Protected Device: How They Work
A surge protector is like a bodyguard for your devices; it blocks or absorbs extra electricity before it can damage anything you have plugged in.
What is a power surge?
A power surge, or voltage transient, is a short burst of excess voltage in an electrical system. The duration is typically in the thousandths or millionths of a second, sometimes recurring. It can be caused by lightning strikes, power outages, large appliances turning on or off, and faults in utility lines. Even small surges can slowly wear down electronics over time.
How does a surge protector work?
Most surge protectors rely on a component called Metal Oxide Varistor (MOV). Under normal conditions, electricity flows from the outlet to your device, but when voltage rises above a safe level, the MOV redirects the excess power away, usually through the ground or neutral. If the surge is strong enough, the protector may sacrifice itself to help protect your equipment.
Protects Devices
Helps protect TV’s, computers gaming systems, phones, and other sensitive electronics.
Adds Convenience
Many models double as multi-outlet power strips for cleaner, easier setups.
Supports Safety
Redirecting excess voltage can help lower the risk of overheating during strong surges.
Reduces Wear
Small surges happen often and can slowly cause internal damage overtime.
Surge Protection Types
Type 1: Protects against large outside surges before they enter the building.
Type 2: Protects the electrical panel and building circuits.
Type 3: Protects everyday plugged-in devices like TV’s, computers, and chargers.
Quick Reminder
Not all power strips are surge protectors.
A regular power strip only gives extra outlets. A surge protector is designed to sense excess voltage and safely redirect it.
Surge protectors are a simple way to protect valuable electronics, extend device lifespan, and improve electrical safety at home.
