Protect electronics from lightning strikes
Surge protection devices
A lightning strike in the vicinity of a building, or near overhead supply lines, suddenly increases the voltage to 3 or 6 kV, instead of 230 V.
The surge, which lasts a few microseconds, can destroy many electronic components: memories, processors, capacitors, screens, etc.
All devices situated within 10 meters distance from the switchboard are effectively protected.
Select appropriate discharge capacity
Building equipped with lightning arrester
If the building features a lightning arrester on the roof a surge arrester of type 1 is required. It must be fitted in the main switchboard, at power incoming point, in addition to the surge arresters selected as above.
A lightning arrester attract the strikes. It drives lightning current to the ground through dedicated ducts, diverting it from the building structure.
