The uncontrolled increase in voltage in the cables can lead to damage or even destruction of connected devices. Before you lose valuable data or devices, and even more so if the described situation has already taken place, it is worth considering the types of surge protection available on the market.
The lightning discharge can be destructive up to several hundred meters from the place of its occurrence. A consequence of the electromagnetic wave may be the appearance of overvoltage in electrical installations, as well as in teletechnical installations. As a consequence, the devices connected to them may be damaged.
Surge protection devices (SPD) are designed to protect teletechnical installations, with varying degrees of effectiveness.
