A lightning strike near a building or overhead supply lines suddenly increases the voltage from 230 V to 3 or 6 kV. The resulting surge, which lasts a few microseconds, can destroy electronic components such as memory, processors, capacitors, and screens.

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. It can also be used at all levels of the power supply network. This is the most commonly used and most efficient type of overvoltage protection
