The Surge Protective Device (SPD) is a component of the electrical installation protection system. This device connects in parallel to the power supply circuit of the loads that it has to protect. The surge protective device redirects electrical currents like nominal discharge current from a short circuit. It does that using either a solid-state contact or an air-gap switch. In addition, the surge protective device serves as a load-safe shutoff device for overcurrent conditions and a recloser that controls the voltage level above the rated voltage or low voltage in the event of a fault condition. We can also use the surge protective device at all levels of the power supply network. This approach is often the foremost commonly used and most effective sort of overvoltage protection.
