What is a power surge?

A power surge, also known as a transient voltage, is a sudden and unexpected increase in voltage in an electrical circuit. This voltage spike can significantly exceed the standard voltage level and last for a very short period, typically milliseconds.

Causes of Power Surges:

  • Lightning Strikes: Direct or nearby lightning strikes are a major cause, injecting massive amounts of energy into the electrical system. Learn more about lightning strikes
  • Power Grid Issues: Problems with the utility company's equipment, such as switching operations or equipment failure, can generate surges. Learn more about power grid issues
  • Internal Appliance Use: High-power appliances like air conditioners, refrigerators, and motors can create small surges when they switch on or off. Learn more about appliance use
  • Faulty Wiring: Problems within the building's electrical system, like loose connections or damaged insulation, can also contribute to surges. Learn more about faulty wiring
