Lightning protection zone and its concept

IEC lightning protection section of the general description:

LPZ0A - Sky, ground outside the building protected by lightning rods, no roof coverings, etc. Grounds etc. Lightning may directly hit the space. For example, the space outside the lightning rod protection area at the top of the building.

LPZ0B - The interior of a non-shielded building without a lightning rod protection, the protected part of the roof of a building protected by a lightning rod, the cables under the lightning conductor, etc., and LEMP, which is not easily hit by lightning, has no attenuation space. For example, the space inside the roof of the building protected by a lightning rod and the interior of an unshielded building or near a window inside a shielded building.

LPZ1-Lightning is not easy to hit directly, but LEMP is attenuated due to shielding. Block the interior of the building as above (not including the window).

LPZ2 - Re-shielded space in LPZ1 area. As described above, the shielded network center established by the shielded building is additionally established.

LPZ3 - In the LPZ2 area, again shielded space. For example, shield the inside of the metal enclosure of the machine in the center of the network, or inside the cabinet that is grounded.

Partitioning of lightning protection in several aspects of overvoltage damage to buildings (structures) and equipment:

According to the principle of electromagnetic compatibility, the IECLPZ lightning protection partition divides the buildings or structures where the information system is located into different lightning protection areas (LPZ) from the outside to the inside to determine the intensity of the lightning impulse electromagnetic pulse in each LPZ space and Take protective measures. Lightning protection areas can be divided into:

Direct strike LPZA: All kinds of objects in this area are completely exposed outside the protection scope of external lightning protection devices, and they may be directly struck by lightning; the electromagnetic field in this area is not completely shielded and attenuated, and is completely exposed. Undefended area.

Direct lightning protection zone (LPZ0B): All objects in this area are within the protection scope of external lightning protection devices and should not be subject to direct lightning strikes greater than the selected ball radius lightning current; however, electromagnetic fields in the area are not obtained. Any shield attenuation is a fully exposed direct lightning protection zone.

The first shielded protection zone (LPZ1): Each object in the area cannot be directly struck by lightning. The current flowing through various conductors is further reduced than in the LPZ0B zone; and due to shielding measures of buildings, the electromagnetic field strength in the area Initial attenuation has also been obtained.

Second Shield Protection Zone (LPZ2): A subsequent protection zone added to further reduce the induced current or electromagnetic field.

The third shielding protection zone (LPZ3) needs to further reduce the lightning strike electromagnetic pulse to protect the subsequent protection zone of sensitive equipment.
