What is a Power Surge?


A power surge, also known as an electrical surge, is precisely what its name suggests—a surge of electrical power that exceeds normal levels. It occurs when an excessive amount of voltage flows through electrical wires and into connected devices. Although these surges are typically short-lived, lasting only a few microseconds, their impact can be considerable. They have the potential to cause significant damage to electronic devices and appliances connected to the circuit. The consequences of a power surge can range from minor glitches and errors to permanent, costly damage that necessitates repair or replacement. In severe cases, electrical surges can even pose a fire hazard. Therefore, understanding what a power surge is, how it occurs, and how to protect against it is crucial.

What Causes a Power Surge in a House?


Power surges in a house can originate from several sources. One frequent culprit is the power grid switching performed by your utility company, which has the potential to generate voltage spikes. Although rare, lightning strikes can unleash massive power surges. Additionally, overloading electrical outlets or enduring power outages can result in surges when power is restored. Lastly, the presence of faulty wiring, including issues like short circuits and overloaded circuits, can be a leading cause of surges. This underscores the significance of regular inspections conducted by a qualified electrician to ensure the safety of your home’s electrical system..

What are the Top Power Surge Causes?


Curious about the most common power surge culprits? Below, we’ve outlined the primary causes of power surges:

#1 – Power Grid Switching

The cause of a power surge may originate from your utility company. The utility company may need to switch the supply of power to another source or temporarily interrupt the flow of power to its customers to aid in clearing a fault in the system. This is often the case in the event of a fallen tree limb or small animal causing a fault on the line. This switch may result in a voltage spike and power surge in your home.

#2 – Lightning

In the rare and unpredictable event that lightning strikes your home’s electrical system, it can unleash a devastating power surge. When lightning makes contact with your electrical infrastructure, it brings forth an overwhelming current that surges through your circuits, wreaking havoc in its path. This sudden influx of electrical energy can lead to severe damage to your electronic devices and appliances, even if it lasts only a fraction of a second.

This unique source of power surges exemplifies the challenges we face as homeowners since we have no control over natural phenomena like lightning strikes. It serves as a reminder of the importance of understanding the power surge definition and taking precautionary measures to protect your valuable equipment from the potential wrath of these uncontrollable electrical events. While we can’t control lightning, we can certainly take steps to safeguard our homes against its unexpected and powerful surges.

#3 – Electrical Overload

One of the most common power surge causes is electrical overload. Do you have too many appliances plugged into an outlet? Do you have extension cords all over your home? This is one of the leading causes of a power surge. Having too many appliances plugged in at one time can cause a massive spike in current due to the excessive power being drawn.

#4 – Power Outage

Power outages and blackouts can occur for a multitude of reasons, leaving us temporarily without electricity. However, when it comes to safeguarding your electronic devices and appliances from potential harm, it’s crucial to pay special attention during the next blackout. Here’s why: when the electrical power is restored after an outage, there’s a potential for an electrical power surge. This sudden and pronounced surge in current can send a wave of electrical energy through your circuits, potentially causing significant damage to any previously unpowered appliances. Understanding this phenomenon is essential in protecting your home from the unexpected consequences of power surging in-house during post-blackout moments.

#5 – Wiring

If you have to ask yourself the question “Why does my power keep surging” faulty wiring may be the reason. It is important to have an electrician inspect and repair any faulty wiring that may be in your home. Faulty wiring can cause a power surge in several ways:

  1. Short circuits: A short circuit occurs when two or more wires in an electrical circuit touch each other, causing a sudden increase in current flow. This sudden increase in current can cause a power surge.
  2. Ground faults: A ground fault occurs when a wire in an electrical circuit comes into contact with a ground surface, such as a metal pipe or the ground itself. This can cause a sudden increase in current flow, leading to a power surge.
  3. Overloaded circuits: Faulty wiring can cause circuits to become overloaded, which can lead to a power surge. This occurs when too many appliances or devices are connected to a circuit, causing the current to increase beyond the capacity of the wiring.
  4. Voltage spikes: Faulty wiring can also cause voltage spikes, which occur when the voltage in an electrical circuit suddenly increases. This can happen if the wiring is damaged or if there is a problem with the electrical supply.
