When the voltage exceeds a certain threshold, the surge protector activates and channels the excess energy to the ground. This action prevents the surge from reaching your devices, thus minimizing the risk of damage.<\/p>\n<h3>How Surge Protectors Work<\/h3>\n<ol>\n<li><strong>Voltage Clamping<\/strong>: Surge protectors contain components, such as metal oxide varistors (MOVs), that clamp down on excess voltage. When the voltage rises above a preset level, the MOV conducts electricity away from the connected devices.<\/li>\n<li><strong>Energy Absorption<\/strong>: Some surge protectors also have built-in capacitors that absorb excess energy, further protecting your devices. This feature is particularly important during high-voltage spikes.<\/li>\n<li><strong>Indicator Lights<\/strong>: Many surge protectors come equipped with indicator lights that show whether the device is functioning correctly. A lit light typically means that the surge protection is active, while a dark light may indicate that the device needs replacement.<\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"types-of-surge-protectors\"><\/span>Types of Surge Protectors<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Surge protectors come in various forms, and understanding the differences can help you choose the right one for your needs:<\/p>\n<h3><strong>1.Plug-In Surge Protectors<\/strong>:<\/h3>\n<p>These are the most common type and are designed for home or office use.
