Understanding Brief Flickers vs Long Power Outages

Power in our daily lives runs a myriad of appliances and devices, but disruptions in this V-ideal flow can vary greatly. This article aims to shed light on the causes of brief power flickers and long power outages. We'll explore what typically happens in each situation, and help you understand how to distinguish between the two.

Brief Flickers: The Culprits

A brief flicker of the power, albeit not a complete outage, is a common occurrence that can often be attributed to minor disruptions in the electrical system. These flickers are usually brief and can be attributed to a host of causes, with the most common being the displacement of a tree branch or an unexpected visit from a squirrel.

Tree Branches and Squirrel Shorts

Tree branches, especially those near power lines, can cause brief periods of low voltage. As these branches alter their position slightly, they can create a partial short circuit on the lines, which results in a dip in voltage. This causes lights to flicker for a moment. Once the branch moves enough to break the connection, the voltage returns to normal, and the lights stabilize. This process is usually swift and barely noticeable to most people.

Squirrels and Their Short Circuits

Tree branches aren't the only culprit. Squirrels can also create brief power flickers. With their playful antics, squirrels can occasionally jump onto a power line, creating a momentary short circuit. This short circuit, in turn, causes the voltage to dip, resulting in a flicker. As soon as the squirrel moves or climbs away, the short circuit is broken, and power stabilizes.

Long Power Outages: Blown Fuses and Reclosers

Power outages that last longer than a few seconds are more serious occurrences and can be caused by various issues.

Fused Lines Due to Shorts

One common cause of a short-term power outage is a blown fuse in a specific section of the line. This usually happens due to a short circuit on that part of the line. A short circuit can be caused by a variety of faults, such as water contact, damaged insulation, or even a more animal-related incident. When a fuse blows, it's designed to protect the circuit from further damage. In such cases, your neighbors' lights are likely to also be out because the issue usually affects a shared line.

Reclosers: The Automatic Protector

A recloser is an automated device designed to help maintain the reliability of power distribution systems. When a short circuit occurs, the recloser will attempt to re-energize the line. If the issue is small and temporary, the recloser will do so several times (usually 3-4 times) before deactivating the circuit if the problem persists. This process is automated and swift, aiming to clear the short circuit and restore power as quickly as possible.

Conclusion and Prevention

Understanding the causes of brief flickers and long power outages can help you better prepare and react to any power disturbances. Regular maintenance and inspections of power lines can reduce the risk of such incidents. If you're experiencing frequent flickers or outages, it might be worth contacting your local utility company to look into the cause and possible solutions.
