What is a Power Surge, and Are They Dangerous?

At its core, a power surge is an abrupt and temporary increase in voltage that exceeds the standard level in an electrical circuit. This surge, often a result of various factors, lasts only microseconds but its impact can be far-reaching and, in some cases, perilous.

Causes of Power Surges

The most dramatic and destructive cause of power surges is lightning. A lightning strike near a power line can send an overwhelming surge into the connected grid. The normal operations of the utility grid can also generate surges, whether due to maintenance activities, sudden changes in power demand, or grid malfunctions.

Causes closer in your sphere of influence are appliances and wiring. The starting and stopping of large appliances such as air conditioners or refrigerators can send ripples through the electrical system, leading to power surges. Defective or worn-out wiring can also cause localized power surges, jeopardizing connected devices.

The Risks of a Power Surge

Power surges can inflict irreparable damage to electronic devices and appliances. Sensitive components within these devices, such as circuit boards and microprocessors, are particularly vulnerable. Even frequent exposure to minor power surges can significantly shorten the lifespan of electronic equipment. Surges can even corrupt or destroy data stored in electronic devices, posing a significant threat to critical information.

In extreme cases, power surges can generate excessive heat, leading to electrical fires that endanger lives and property.

How Do Surge Protectors Help?

Surge protectors are devices which regulate the voltage supplied to connected devices. By establishing a safe threshold, these devices prevent excessive voltage from reaching sensitive electronics.
