Lightning Strikes
One major cause of power surges is lightning strikes. When lightning hits, nearby power lines experience a sudden spike in energy. This power spike travels through the wiring and reaches your home, where it can damage delicate electronic equipment. Even if lightning does not hit your property directly, a strike on nearby infrastructure can cause a surge that ripples into your electrical system.
Utility Switching & Transformer Issues
Another reason for power surges is the switching activities of utility companies. When there is a change in load or during routine maintenance, utilities may switch between power sources or adjust transformer outputs. These actions can create temporary but significant voltage spikes. In cities like St Louis and Nashville, where the power grid experiences high demand, these events can be more frequent and cause additional stress on the local system.
Faulty Wiring and Installation Errors
Improper wiring or installation errors in a home or building can also lead to power surges. Loose connections, degraded wiring insulation, or outdated electrical panels create conditions where voltage may fluctuate unexpectedly. These issues are not always visible and may build up stress on the system until a surge occurs, which then damages connected electronics.
Appliance and Equipment Malfunctions
The operation of large appliances and industrial equipment can trigger surges. When these devices cycle on and off, they create sudden changes in current flow. This can send shock waves through the wiring. Such surges are common in homes with older or malfunctioning appliances that intermittently draw excessive current.
Environmental and External Factors
Other factors include tree branches interfering with power lines, falling debris, or even animals chewing on cables. These external disturbances can disrupt the stable operation of power lines, allowing surges to happen. In regions with harsh weather, such as windstorms or heavy rains, these risks are increased.
Issues with Grounding
Good grounding is essential for absorbing unwanted electrical surges. Poorly grounded systems are unable to divert excess energy safely, which means more of the surge is directed into your home’s wiring. A grounding issue might not be obvious until an unexpected surge occurs, damaging devices that are not protected.
