What Causes Power Surges


First things first, let’s explore what causes power surges. A power surge is a sudden, temporary spike in your home’s electrical current, triggered by various factors. External events like lightning strikes can forcefully inject excessive electricity into your home’s wiring. Similarly, community power grid issues, such as outages or malfunctions, can cause surges when power is abruptly restored. Internally, high-powered appliances in your home, like air conditioners or refrigerators, can create surges as they demand large amounts of electricity to start or stop, disrupting the steady flow of current. These brief yet potent surges can potentially harm your home’s sensitive electronics, making it crucial to understand and guard against these occurrences.

What is Surge Protection?

  • Surge protection is your main line of defense against these surges. It’s a system or device designed to protect electronic devices from voltage spikes. Think of it as a gatekeeper, ensuring that any excess electricity doesn’t make its way into your home’s electrical system and cause damage.

Now that we have a solid understanding of surge protection, let’s start exploring the various Types of Power Surges. This knowledge is key in identifying and effectively addressing the specific surge issues you might encounter. These differences are crucial for implementing the most effective protection strategies

Types of Power Surges


In our exploration of Types of Power Surges, it’s important to recognize that not all surges are created equal. Generally, power surges fall into two main categories: internal and external. Internal power surges are common and often occur multiple times a day, typically caused by high-powered appliances cycling on and off within your home. These surges, though less dramatic, can gradually damage electronics over time. On the other hand, external power surges are less frequent but more severe. They can result from lightning strikes, spikes in electrical supply, or major disturbances in the power grid. Both types pose risks to our homes, from the nuisance of resetting clocks to the more serious threat of damaging sensitive electronics. Understanding the nature and origin of these surges is crucial for effective electrical surge protection and maintaining the integrity of our home’s electrical systems.

Internal Power Surge

  • An internal power surge occurs from within your home. This is often the result of devices with motors starting up or shutting down, like your refrigerator or air conditioner. These devices require a lot of energy to start, and this sudden demand can disrupt your home’s steady electrical flow, leading to a surge.

External Power Surge

  • An external power surge is caused by outside factors. This could be due to lightning strikes, downed power lines, or changes in the electricity supply from your utility company. These surges are less frequent but can be more severe and potentially damaging.

Power Surges Prevention


When it comes to Power Surge Prevention, being proactive is key to protecting your home from unexpected electrical surges. The first step is understanding that power surges can occur at any time, whether due to internal factors like cycling appliances or external events like lightning strikes. Implementing industrial surge protection methods, even in a residential setting, can provide a robust defense against these surges. This might involve installing surge protectors at critical points, ensuring your home’s wiring is up to date, and regularly inspecting your electrical system for any vulnerabilities. Additionally, being aware of what causes a power surge and taking simple precautions, like unplugging devices during a storm, can mitigate the risk of damage. Remember, preventing power surges in your home isn’t just about protecting electronics; it’s about ensuring the overall safety and longevity of your home’s electrical infrastructure.

How to Prevent a Power Surge

  • Unplug unused devices (this can also help you save on electricity!)
  • Upgrade your wiring
  • Don’t overload your circuit
  • Use a surge protector

Preventing power surges in your home involves a few strategic steps. First, consider installing a whole-house surge protector, which can safeguard your entire electrical system. Additionally, unplugging devices during a storm or when they’re not in use can minimize the risk. It’s also wise to invest in individual surge protectors for high-value electronics.

What is a Power Surge Protector?


The question “What is a surge protector?” is pivotal in our quest to safeguard our homes from electrical mishaps. A surge protector is a device designed to protect your home’s electronics from sudden power surges and electrical spikes. When a surge occurs, the protector acts as a barrier, either blocking the excess electricity or redirecting it to the ground, thus preventing it from reaching and damaging connected devices. There are various types of surge protectors, ranging from simple outlet strips to sophisticated whole-house systems. These protectors are particularly crucial in areas prone to lightning or where electrical surges in house are common. Incorporating surge protection into your home’s electrical system is a proactive measure that can prevent costly repairs and extend the life of your electronic devices, thereby maintaining the integrity and efficiency of your home’s power system.

Different Types of Surge Protectors

  • Whole house or panel-mounted
  • Power strips with surge protection
  • Transient Voltage Surge Suppressors (TVSS)

A power surge protector is a device that shields your electronics from excess voltage during a surge. There are several types of surge protectors, from basic models that you plug into an outlet, to more complex systems like whole-house surge protectors. The right choice depends on your specific needs and the level of protection you require.

How to Know if You’ve Had a Power Surge


Understanding “How to Know if You’ve Had a Power Surge” is crucial for homeowners aiming to maintain the health and safety of their electrical system. Firstly, a power surge can manifest subtly or dramatically, but certain signs are key indicators. You might initially notice your lights flickering or electronic devices resetting unexpectedly, common symptoms of a power surge in the house. More severe signs, such as damaged appliances, scorched outlets, or a distinct burnt odor near electrical devices, suggest a significant electrical power surge. Additionally, it’s wise to be vigilant of a surge of electricity following storms or power outages. Recognizing these signs early can help you respond effectively, whether that involves checking your surge protection circuit or consulting a professional, thus ensuring the ongoing safety and integrity of your home’s electrical systems.

Signs of a Power Surge

  • The clock or lights are flashing on an electrical device or appliance
  • The electrical device or appliance is off or does not work
  • There is a burnt odor around the device or power source
  • A surge protector or power strip may require resetting

When to Call a Professional

If you suspect a power surge in your house, it’s often best to call a professional. An electrician can assess the damage, repair any issues, and provide advice on surge protection. If your surge protectors are frequently tripped or experience frequent surges, this could indicate a deeper electrical issue requiring professional attention.

Electrical surges in the house are not just an inconvenience; they can pose serious risks to your appliances and safety. By understanding the types of surges and how to protect your home, you can prevent potential damage and ensure your electrical system runs smoothly. Remember, a small investment in surge protection can save you from costly repairs in the long run. Stay safe, stay informed, and protect your home from the unexpected jolts of everyday life.
