A power surge may last only a fraction of a second, but the results inside the home can be long-lasting or even catastrophic. Additionally, brownouts, or drops in voltage in an electrical power supply system, often result in a surge as power is restored. Faults or fires in main transformers or generating equipment can cause a disruption in your home’s power supply. Extreme weather conditions like hurricanes, tornadoes, blizzards, and thunderstorms pose obvious power-outage threats, but other factors contribute to voltage surges more often than you might realize.
