How does a power surge happen?
Power surges occur when the flow of electricity is interrupted, then started again, or when something sends electricity flowing back into the system. Surges can range from five or ten volts when you turn on your hair dryer to thousands of volts if lightning strikes a transformer.
How does a power surge protector work?
It works by pulling the current from one outlet and passing it through to the devices you have plugged into the surge protector. A surge protector contains
, or MOV, which diverts any extra voltage to ensure devices receive a consistent power level. The MOV works like a pressure-sensitive valve.
