How Surge Protection Devices Work<\/h2>\r\n<h3 data-start=\"2693\" data-end=\"2734\">2.1 Diverting Surge Current to Ground<\/h3>\r\n<p data-start=\"2736\" data-end=\"2935\">SPDs detect overvoltage and instantly open a low-resistance path to divert surge current away from protected loads. This energy is sent to the ground, preventing insulation damage or circuit failure.<\/p>\r\n\r\n<h3 data-start=\"2937\" data-end=\"2987\">2.2 Voltage Clamping and Limiting Peak Voltage<\/h3>\r\n<p data-start=\"2989\" data-end=\"3198\">SPDs clamp the peak voltage to a predefined safe level. For example, a 230V system might limit transient peaks to under 1.5kV. MOVs, GDTs, and TVS diodes commonly perform this function.<\/p>\r\n\r\n<h3 data-start=\"3200\" data-end=\"3231\">2.3 Transient Response Time<\/h3>\r\n<p data-start=\"3233\" data-end=\"3445\">Top-tier SPDs react in nanoseconds (typically &lt;25 ns), making them suitable for high-speed digital systems and programmable controllers. This fast response is key to preventing internal component degradation.<\/p>\r\n\r\n<h3 data-start=\"3447\" data-end=\"3493\">2.4 Importance of Grounding &amp; Coordination<\/h3>\r\n<p data-start=\"3495\" data-end=\"3719\">Grounding systems must be low-impedance for surge energy to dissipate effectively. Additionally, SPDs must coordinate with upstream protection like fuses or MCBs, especially in installations with high Isc (&gt;6kA).<\/p>\r\n\r\n<h3 data-start=\"3721\" data-end=\"3788\">2.5 Protection of Sensitive Electrical and Electronic Equipment<\/h3>\r\n<p data-start=\"3790\" data-end=\"3923\">Sensitive systems like PLCs, inverters, servers, and medical equipment are most vulnerable.
