What is a Voltage Surge

A voltage surge, also known as a power surge or transient voltage, refers to a short-duration increase in voltage above the normal levels in an electrical circuit. These surges can vary in magnitude and duration and can be caused by various factors, such as lightning strikes, power outages, short circuits, or the operation of high-power electrical devices.

Voltage surges can potentially damage or degrade electronic devices and electrical equipment connected to the affected circuit. Common examples of such equipment include computers, televisions, appliances, and other sensitive electronics. To protect against voltage surges, people often use surge protectors or suppressors, which are devices designed to limit the voltage supplied to an electric device by blocking or shorting to ground any unwanted voltages above a safe threshold. These devices help safeguard electronic equipment from potential damage caused by voltage surges.
