5 Power Surge Causes and Prevention Tips. 1. Wiring
Damaged or exposed wiring can result in frequent power surges. Sometimes they can occur multiple times in a day, risking damage to home appliances and electronic devices, including outlets and switches.
Internal power surges can go unnoticed, but there are some tell-tale signs. The most common ones are a burning smell and warm outlets. However, one must be careful because ignoring these problems for too long can result in harmful damages, including short-circuiting. 2. Lightning
Lightning can have drastic effects when it strikes; it can cause fires and power outages, and even blackouts. An electrical surge from a lightning strike can ruin electronics and appliances around the house. The damage occurs because the voltage spike is so high that home appliances like TVs, chargers, microwaves, or anything plugged in or connected to the main electric panel cannot withstand the electrical voltage intensity. Even plugged-in but switched off devices can suffer the same consequences. 3. External Factors
External factors that can cause an electric surge include weather conditions, trees, and animals. Extreme weather conditions, such as snowstorms, thunderstorms and sweltering temperatures, can result in power surges.
Tree limbs can also cause power surges. Sometimes, the tree branches touch the power lines - can cause an electrical surge. It may not be as damaging as other causes, but enough electrical surges can damage home appliances over time. Keeping this in mind, trimming trees would be better left to professional services; never try to remove a broken tree limb from a power line.2
Animals, too, can cause power surges. Wild animals such as squirrels, birds, and even snakes in some regions can be the culprits. Small animals can make their way into transformers or even nibble away at cable, exposing the wiring inside which can result in dangerous effects like short-circuiting. 4. Overload
Quite often, office buildings face short-term power outages, some that last for just a few seconds. It is usually the case with commercial buildings where an electrical overload can momentarily trip the circuit. The overload occurs because of the systems' sizes in commercial buildings, like elevators or multiple air-conditioning units. Imagine an office building and the number of appliances and devices that may overload the electrical network.
Overloading can also occur in residential homes; some appliances consume more electricity than others, for instance, refrigerators, hairdryers, blenders, etc. When there is a sudden spike in electricity use, it can cause a surge and damage the appliance.3 5. Momentary Outages
As stated, even momentary outages can result in electrical surges. When frequently occurring, these hiccups to the electrical flow can trip the circuit or cause a sudden electricity burst. Either way, it can damage electrical equipment. Momentary outages are usually the result of external factors rather than internal ones.
