How Does a Surge Protector Work?
Surge protectors are an essential line of defense for your electronic devices, safeguarding them from potentially damaging power surges. But how exactly do surge protectors work? Let’s delve into the inner workings of these protective devices.
When a power surge occurs, surge protectors detect the sudden increase in voltage and spring into action. They use various components, such as metal oxide varistors (MOVs), to divert excess voltage away from the devices plugged into them.
Metal Oxide Varistors (MOVs)
Surge protectors employ metal oxide varistors (MOVs), which are voltage-sensitive devices that act as barriers against damaging surges. These MOVs have high resistance at normal operating voltages, allowing electricity to flow normally. However, when a surge exceeds the MOV’s threshold voltage, its resistance decreases significantly, absorbing the excess voltage and redirecting it safely to the ground.
By absorbing the excess voltage, surge protectors prevent it from reaching your devices and causing irreparable damage. They act as a first line of defense, sacrificing themselves to guard your valuable electronics.
Indicator Lights and Alarms
Many surge protectors are equipped with indicator lights or alarms to notify users when they need to be replaced. These features serve as a helpful reminder to ensure optimum protection for your devices.
