What Is A Voltage Protector?

A voltage protector is designed to protect electronic appliances from a voltage surge, which is an increase in voltage above a designated level in a flow of electricity. Some jurisdictions operate on 120-volt electricity flow and others operate on 220-volt electricity flow. The voltage protector protects electronic devices from a change in electricity flow. If the increase in voltage is too high, it can damage or ruin an electrical appliance.
