what causes a power surge

This type of problem happens most often when your home has faulty wiring. This causes an increase in the electrical potential energy, which can increase the current flowing to your wall outlet. When lightning does strike your electrical system, it has no choice but to accept the overwhelmingly excessive current. The most common causes of power surges are actually small things, like turning on an electrical device that is too high-powered, such as refrigerators, AC units or even space heaters, thereby creating a small spike in the electrical current. This means whether the cause is an electrical overload, faulty wiring, lightning, or a power outage, whole-home surge protection will still act against power surges. High Power Electrical Devices. The most common causes are lightning, utility grid switching, other users on the power line, and internal surges from air conditioner and power tools. Contact Roman Electric at 414-771-5400 for our surge protection services. Electrical overloads can lead to power surges as the overwhelmed circuit may receive a massive spike in current due to the excessive power being drawn. Sometimes you may even smell smoke as the wires melt or burn up due to the abnormal flow of voltage. Lightning strikes are another cause. Tripped circuit breakers and short circuits can also create spikes in current. Yet, while spikes don’t often last long, they can be powerful enough to cause damage to electronic devices and electrical wiring — and even lead to electrical fires. If an appliance can’t handle the overload, it can be damaged or even completely ruined. A common cause of power surges, especially the most powerful ones, is lightning. While lightning may actually strike the circuit itself causing a power surge, a far more common cause of voltage surges is lightning hitting circuits nearby. We're here to help.
