LOCATION AND ARRANGEMENT

Selection of SPDs according to the lightning protection zone (LPZ) concept

SPDs shall be selected and installed in accordance with the requirements of the HD 60364-4-443 and the IEC and EN 62305 series of standards respectively, and the HD 60364-5-534. The primary SPDs shall be located as close as possible to the origin of the installation. In many cases this will be the Main Distribution Board (MDB). Further SPDs will most likely be located in Sub Distribution Boards (SDBs).
Following the philosophy of the lightning protection zone concept right from the planning phase of an installation, it is first necessary to define and separate into areas (so called zones) within a structure, which require a certain level of protection, depending on the resistivity and immunity of the equipment installed and used there. The higher the protection requirements are, the higher is the corresponding Zone number.
Based on that the progressive attenuation of transients and electromagnetic inteferences is achieved through the installation of coordinated SPDs at the boundaries of the zones defined.
The objective is to reach a fully compatible system, where all electric and electronic equipment is sufficiently protected not to face any transients or interference it is not able to withstand. By doing this service continuity and the integrity of equipment should be guaranteed.
