During intense bouts of stormy weather, you may notice the lights in your home flicker. Many people view this phenomenon as a normal aspect of storms. However, flickering lights are often the result of surges in your home’s power supply, which can be detrimental to your appliances.
Power Surges Defined
In most homes, electricity is delivered with an alternating current. Although referred to as 120V, the actual current can range from 0 to 169 during normal conditions. Fortunately, common electronics and appliances are designed to handle natural changes in energy supply. During power surges, voltage can significantly exceed 169, which can be damaging to appliances and electronics.
Power Surge Prevention
While there’s no way to stop power surges from occurring, there are two ways homeowners can protect themselves against damage from power surges:
- Point-of-Use Devices: Commonly referred to as surge protectors, point-of-use devices prevent power surges from reaching electronics. Instead of allowing the surge to affect devices, the power from the surge is directed by point-of-use devices into the ground.
- Service Entrance Surge Protector Devices: These devices are typically installed near your circuit breaker, electric panel or electric meter and are necessary to protect the portions of your electric system that are not plugged in to an outlet.
