A power surge is a sudden increase in voltage that can destroy or burn out the electronic devices and appliances in your home. They might last only a portion of a second, but the damage can be expensive and inconvenient. The installation of surge protection, especially a whole-house surge protector, protects your home’s electrical system and allows for years with valuable electronic equipment. The following guide will elaborate more on what surge protection is, how it works, the risks involved in a power surge, and why investment in surge protection will be wise for every homeowner.

Understanding Power Surges

What Is a Power Surge?

A power surge, also called a transient voltage, is a generally momentary increase in voltage beyond what the standard flow of electricity exceeds. House voltage in the United States usually runs at about 120 volts, and any major jumpover can cause a surge. These surges can range from minor, unrecognized fluctuations to significant spikes that may promptly destroy an electronic device.

Sources of Power Surges

Power surges originate from both internal and external sources, including:

Lightning Strikes: A lightning strike near an electrical line can force a lot of electrical power through the electrical grid in the form of a large surge.
Electrical Overloads: Too many high-powered appliances operating simultaneously overload circuits, leading to surges when such devices are turned off or on.
Bad Wiring: Improperly installed, damaged, or exposed wiring may develop voltage spikes at irregular intervals, increasing the possibility of a surge.
Power Outlets and Grid Switching: These may also be caused when the power suddenly comes on after an outage or when utility companies switch power grids.
High-Powered Appliances: Such appliances include air conditioners, refrigerators, and pumps, which are very well known to cause surges each time they cycle on and off because of the immediate requirement for power.

Frequency of Power Surges

Though catastrophic surges due to lightning strikes are rare, minor ones occur in many homes every day. These minor surges build up over time and degrade the performance and eventually shorten the life span of electronic equipment.

Risks of Power Surges

Immediate Damaging to Electronics and Appliances

Power surges can:

Fry Circuit Boards: Excess voltage may burn the internal sensitive components within the electronics and render them useless.
Shortened Life Span: Minor surges repeatedly can gradually degrade devices and result in an early failure.
Data Loss: Computers, external hard drives, and other storage units can erase data in the case of surges and can delete a few important documents or precious photos that cannot be recovered.

Hidden Damage

Not all damage due to power surges is visible. Devices could still work, but with degraded parts leading to

Reduced Efficiency: Appliances consume more energy or work less efficiently.
Unexpected Failures: Electronics can fail without warning, often at inconvenient times.

Fire Hazards

Overheated Wiring: Surges can cause wiring to overheat, increasing the risk of electrical fires.
Damaged Insulation: Repeated surges can degrade wire insulation, exposing conductive materials.

Financial Loss

Replacement Costs: Replacing damaged appliances and electronics can be very expensive.
Repair Costs: Repairing an electrical system damaged by a surge can be expensive, especially if wiring or circuit breakers are involved.
Increased Insurance Premiums: Frequent claims related to surge damage may result in higher homeowner’s insurance premiums.

What Is Surge Protection?

How Surge Protectors Work

Surge protectors protect your electrical devices by:

Voltage Limiting: They keep the voltage entering an electrical device constant. They will block or short to the ground any voltages beyond a threshold.
Surge protector redirects excess voltage to a grounding wire, thus keeping them away from devices connected.
Response Time: A surge protector will have quality according to response time, i.e., how fast it takes over excess voltage and lower it.

Components of a Surge Protector

Metal Oxide Varistor (MOV): The heart of the surge protector that shunts off the excess voltage. It possesses resistance that varies with voltage.
Gas Discharge Arrestors: Higher-end models employ these to protect against large surges, like those caused by lightning.
Fuse or Circuit Breaker: This saves the surge protector from being destroyed in case of overload.

Types of Surge Protection

Point-of-use surge Protectors: This includes individual devices like surge-protected power strips used to protect specific appliances or sets of electronic appliances.
Whole-House Surge Protector: These are installed at the point of your main electrical panel at home to protect all electrical devices inside a home from external surges.
Service Entrance Surge Protectors: These are mounted on the point where electricity gets into the house, giving another layer of protection to the electrical panel in that house. TVSS – Transient Voltage Surge Suppressors Used commercially for high-level protection.
