What is a power surge?
A power surge is a sudden and brief increase in the electrical voltage that flows through your home’s electrical system. These surges can last for just a fraction of a second, but they can cause significant damage to your electronic devices and appliances. Power surges can occur for various reasons, such as lightning strikes, utility grid issues, or electrical equipment malfunctions.
Causes of power surges
Lightning strikes
One of the most common causes of power surges is lightning strikes. When lightning strikes either directly hits your home or strikes nearby power lines or utility equipment, it can send a massive surge of electricity through the electrical system. Even if the lightning strikes some distance away, the sudden changes in the electric fields can still induce power surges through the utility lines, affecting your home.
Utility grid issues
Issues within the utility grid itself can also lead to power surges. Problems such as malfunctioning transformers, downed power lines, or sudden shifts in the power demand can cause voltage spikes. These spikes can then travel to your home and potentially damage your electronic devices and appliances.
Electrical equipment malfunctions
Electrical equipment in your home, such as air conditioners, refrigerators, or even faulty wiring, can also cause power surges. When these devices experience a sudden malfunction, it can generate high electrical currents that disrupt the normal flow of electricity. These surges can travel through the circuit and affect other devices connected to the same electrical network.
How power surges affect electronic devices
Voltage spikes
Power surges, especially the ones caused by lightning strikes or utility grid issues, can result in voltage spikes. These spikes can exceed the normal operating voltage range of your electronic devices, leading to their malfunction or failure. The sudden surge of electrical energy can overwhelm the internal components, causing them to be permanently damaged.
Overheating
Another way power surges can affect your electronic devices is through overheating. When a surge occurs, the excess electricity can cause increased heat in the device’s circuitry. If the heat generated exceeds the device’s capacity to dissipate it, the components can become damaged, resulting in reduced performance or even complete failure.
Temporary or permanent damage
Power surges can cause both temporary and permanent damage to your electronic devices. In some cases, a surge may only affect the device temporarily, resulting in glitches, system crashes, or temporary power loss. However, if the surge is severe enough, it can cause irreversible damage, rendering the device completely useless or requiring expensive repairs.
Signs of power surges
Flickering lights
One of the most noticeable signs of power surges is flickering lights. If you frequently experience sudden dimming or brightening of lights, it could indicate that there are power surges occurring in your home’s electrical system. While occasional flickering may not be a cause for concern, persistent and frequent occurrences should be investigated further.
Tripped circuit breakers
If your circuit breakers constantly trip for no apparent reason, it could be a sign of power surges. Power surges can overload the electrical circuits, causing the circuit breakers to automatically shut off the flow of electricity. If you find yourself frequently resetting tripped breakers, it’s important to identify and address the underlying cause.
Burning smell
A burning smell coming from your outlets, appliances, or electrical panels can indicate power surges. When electrical components are exposed to power surges, they can overheat and even become scorched. If you notice a burning smell, it’s crucial to turn off the affected circuit immediately and have a professional inspect the electrical system to prevent potential fire hazards.
Malfunctioning or damaged appliances
If your appliances suddenly stop working or exhibit erratic behavior, it could be a result of power surges. Power surges can damage the internal circuitry of appliances, causing them to malfunction or fail altogether. If multiple devices in your home are experiencing issues simultaneously, it’s highly likely that power surges are the culprit.
Protecting against power surges
Unplugging devices during storms
To protect your electronic devices during thunderstorms or other instances where power surges may occur, it is advisable to unplug them from the electrical outlets. By disconnecting your devices from the power source, you eliminate the risk of power surges damaging them. This simple precautionary measure can save you from potential losses and the hassle of repairing or replacing your valuable electronics.
Using surge protectors
One of the most effective ways to safeguard your electronic devices is to use surge protectors. Surge protectors are devices that provide a barrier between your devices and the incoming electrical supply. They work by diverting the excess voltage from power surges, preventing it from reaching your devices. It’s important to note that surge protectors have a limited lifespan and should be replaced periodically.
Installing a whole-house surge protector
For enhanced protection against power surges, consider installing a whole-house surge protector. Unlike individual surge protectors, which only protect the devices plugged into them, whole-house surge protectors defend your entire electrical system. These protectors are typically installed at the main electrical panel of your home and can provide protection against both internal and external power surges.
Regular maintenance and inspections
Regular maintenance and inspections of your electrical system can help identify potential issues that could lead to power surges. By having a licensed electrician assess the condition of your wiring, outlets, and electrical panels, you can address any problems before they escalate.

Uninterruptible Power Supply (UPS)
Sensitive electronic devices, such as computers, servers, and data storage systems, require an additional layer of protection. An Uninterruptible Power Supply (UPS) provides both surge protection and battery backup. In the event of a power surge or outage, the UPS seamlessly switches to battery power, allowing you to safely shut down your devices to prevent data loss or system damage.
Isolating equipment with dedicated circuits
Isolating sensitive equipment with dedicated circuits can minimize the risk of power surges. By connecting critical electronics, such as home theater systems or high-end audio equipment, to separate circuits, you reduce the likelihood of power surges caused by other appliances or devices in your home. This isolation provides an added layer of protection for your valuable and sensitive electronics.
Power conditioner
Power conditioners are another option for surge protection, particularly for audio and video equipment. They not only protect against power surges but also filter out electrical noise and stabilize voltage levels. Power conditioners are especially beneficial in areas with unreliable power quality, as they ensure a stable and clean power supply to your sensitive electronics.
The importance of surge protectors
How surge protectors work
Surge protectors work by diverting excess electrical voltage from power surges to the grounding wire. Inside surge protectors, there are metal oxide varistors (MOVs) or gas discharge tubes that detect and absorb the surge energy. By shunting the excess voltage away from your devices, surge protectors help prevent damage and provide a line of defense against power surges.
Types of surge protectors
There are various types of surge protectors available to suit different needs. Basic surge protectors provide a decent level of protection for everyday devices and appliances.
