How Do Surge Protectors Work?
Surge protectors work by diverting excess electrical current away from delicate electronics. Here is a more detailed explanation of how they work:
⏩ They have metal oxide varistors (MOVs) inside that act like voltage-sensitive resistors. MOVs remain highly resistive when voltage is at normal levels. However, if voltage spikes, the MOVs quickly switch to becoming conductive, shorting the extra voltage to ground.
⏩ They also contain capacitors that can absorb excess electrical energy. The capacitors smooth out power fluctuations and provide extra protection from spikes.
⏩ Some surge protectors have an internal fuse that will blow if the current rises above unsafe levels, sacrificing itself to protect connected devices. The fuse has to be replaced if this happens.
⏩ There is often an indication light that alerts if the MOVs have been triggered and the protection capacities are reduced. This signals it's time to replace the surge protector.
⏩ Higher-quality surge protectors will have a fast response time in diverting extra current and a higher joule rating, meaning they can absorb more energy before being damaged. This provides better protection for electronics.
