How surge protectors work
Surge protectors are designed to shield electronic devices from voltage spikes that can cause irreparable damage. Understanding how surge protectors work can help you make informed decisions when purchasing and using these devices.
As mentioned earlier, surge protectors use metal oxide varistors (MOVs) to redirect excess voltage away from your devices. When the voltage exceeds a certain threshold, the MOVs activate and create a low-resistance path for the excess voltage to follow. This diverts the excess voltage to the ground, preventing it from reaching your devices.
In addition to MOVs, surge protectors may also include other protective components, such as gas discharge tubes or avalanche diodes, to provide additional layers of protection. These components work together to ensure that your devices are shielded from power surges.
