Protection device electrical equipment does not store energy
Surge Protection Devices (SPDs) are essential components that protect electrical systems and equipment from transient overvoltages, commonly known as electrical surges.
ABB surge protective devices
A device designed to limit surge energy to electrical equipment. It does this by diverting or limiting surge current. An SPD is wired in parallel to the equipment it is intended to protect. Once the surge voltage exceeds its designed rating, it "begins to clamp" and starts to conduct energy directly to the electrical grounding system.
Overvoltage Protection
Surge Protection Devices (SPD) are used for electric power supply networks, telephone networks, and communication and automatic control buses. The Surge Protection Device (SPD) is a component of the electrical installation protection system. This device is connected in parallel on the power supply circuit of the loads that it has to protect.
