Elke SPD reduceert de piekspanning naar apparatuur tijdens een piek naar een op spanning getest niveau dat bekend staat als doorlaatspanning.\r\n\r\nSoorten bescherming<\/strong>\r\n\r\nBij het bespreken van verschillende soorten overspanningsbeveiliging zijn er drie hoofdtypen:\r\n\r\n\r\n\r\n\r\n\r\n\r\n
Type<\/td>\r\nWat het doet<\/td>\r\nWaar te gebruiken<\/td>\r\n<\/tr>\r\n
Type 1<\/td>\r\nBescherming tegen directe blikseminslagen<\/td>\r\nOp de netingang van elke elektrische installatie waar externe bliksembeveiliging is ge\u00efnstalleerd of wordt gevoed door bovengrondse lijnen.<\/td>\r\n<\/tr>\r\n
Type 2<\/td>\r\nOverspanningsbeveiliging<\/td>\r\nAan de netingang van elk gebouw dat geen bliksembeveiliging nodig heeft, en voor gebruik op subborden op meer dan 10-15 meter afstand van het hoofdpaneel.<\/td>\r\n<\/tr>\r\n
Type 3<\/td>\r\nBescherming van eindapparatuur<\/td>\r\nOp elk apparaat waar een lage doorlaatspanning nodig is.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nWat is de juiste manier om te bepalen welk SPD-formaat in een systeem moet worden gebruikt?<\/strong>\r\n\r\nSPDs are not one-size-fits-all devices, nor do the sizes of their kA rating (the surge rating) go hand-in-hand with the size of the panel. In other words, do not select an SPD with a maximum kA rating just because the panel is large.\r\n\r\nTo determine which SPD should be used for the system, you must know the reference to the ground as well as the type of voltage that is present. Therefore, a panel designer should first determine the type of electrical system in use, and then calculate the voltage reference to ground. The formula to determine this will depend on the type of system.\r\n\r\nFor example, for a single-phase system (also called a split-phase system), the line-to-line voltage is divided by two. The result is the optimal amount of volts that the SPD should have for that system.\r\n\r\nHoe u een apparaat kiest<\/strong>\r\n
    \r\n \t
  • Is het apparaat geschikt voor uw aardingsinstallatie?<\/li>\r\n<\/ul>\r\nDit is een van de meest voorkomende problemen bij de installatie van SPD. De belangrijkste overweging geldt voor TT-systemen, waarbij het apparaat geschikt moet zijn.\r\n
      \r\n \t
    • Beschermt het apparaat zowel de actieve als de neutrale polen?<\/li>\r\n<\/ul>\r\nEr zijn een paar apparaten op de markt die misschien goedkoop lijken in vergelijking met andere apparaten, maar als het apparaat niet zowel live als neutraal beschermt, kunnen spanningspieken uw eigendom binnendringen en de SPD omzeilen.\r\n
        \r\n \t
      • Welke garantie biedt de fabrikant?<\/li>\r\n<\/ul>\r\nDit is over het algemeen een belangrijke indicator voor de kwaliteit van de componenten die in de SPD worden gebruikt.\r\n\r\nAankoop van het juiste overspanningsbeveiligingsapparaat (SPD).<\/strong>\r\n\r\nHoewel elke SPD het piekspanningsniveau dat naar elektrische apparatuur gaat tijdens een piekgebeurtenis zal verminderen, hebben sommige een doorlaatspanning die te hoog is om schade te voorkomen, wat bijna hetzelfde is als helemaal geen bescherming hebben.

          \r\n \t
        • Is the device suitable for your earthing arrangement?<\/li>\r\n<\/ul>\r\nThis is one of the most common issues with SPD installation. The most important consideration is for TT systems, where the device needs to be suitable.\r\n
            \r\n \t
          • Is the device protecting both the live & neutral poles?<\/li>\r\n<\/ul>\r\nThere are a few devices on the market with may seem inexpensive compared to other devices, but if the device is not protecting both live & neutral, surges may enter your property and bypass the SPD.\r\n
              \r\n \t
            • What warranty does the manufacturer provide?<\/li>\r\n<\/ul>\r\nThis is generally a key indicator of the quality of the components used in the SPD.\r\n\r\nPurchasing the Right Surge Protective Device (SPD).<\/strong>\r\n\r\nWhile any SPD will reduce the surge voltage level passing to electrical equipment during a surge event, some have a Let-Through-Voltage that is too high to prevent damage, which is almost the same as having no protection at all.
