Jedes SPD reduziert die Sto\u00dfspannung an Ger\u00e4ten w\u00e4hrend eines Sto\u00dfes auf einen gepr\u00fcften Spannungspegel, der als Durchlassspannung bezeichnet wird.\r\n\r\nArten des Schutzes<\/strong>\r\n\r\nBei der Er\u00f6rterung verschiedener Arten von \u00dcberspannungsschutz gibt es drei Haupttypen:\r\n\r\n\r\n\r\n\r\n\r\n\r\n
Typ<\/td>\r\nWas es bewirkt<\/td>\r\nWo kann man es verwenden?<\/td>\r\n<\/tr>\r\n
Typ 1<\/td>\r\nSchutz vor direkten Blitzeinschl\u00e4gen<\/td>\r\nAm Netzeingang jeder elektrischen Anlage, in der ein externer Blitzschutz installiert ist oder die \u00fcber Freileitungen gespeist wird.<\/td>\r\n<\/tr>\r\n
Typ 2<\/td>\r\n\u00dcberspannungsschutz<\/td>\r\nAm Haupteingang jedes Geb\u00e4udes, das keinen Blitzschutz ben\u00f6tigt, und zur Verwendung auf allen Nebenplatinen, die mehr als 10\u201315 Meter vom Hauptschaltfeld entfernt sind.<\/td>\r\n<\/tr>\r\n
Typ 3<\/td>\r\nEndger\u00e4teschutz<\/td>\r\nAn allen Ger\u00e4ten, an denen eine niedrige Durchlassspannung erforderlich ist.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nWie l\u00e4sst sich richtig bestimmen, welche SPD-Gr\u00f6\u00dfe in einem System verwendet werden soll?<\/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\nSo w\u00e4hlen Sie ein Ger\u00e4t aus<\/strong>\r\n
    \r\n \t
  • Ist das Ger\u00e4t f\u00fcr Ihre Erdungsanordnung geeignet?<\/li>\r\n<\/ul>\r\nDies ist eines der h\u00e4ufigsten Probleme bei der SPD-Installation. Die wichtigste \u00dcberlegung betrifft TT-Systeme, bei denen das Ger\u00e4t geeignet sein muss.\r\n
      \r\n \t
    • Sch\u00fctzt das Ger\u00e4t sowohl die stromf\u00fchrenden als auch die neutralen Pole?<\/li>\r\n<\/ul>\r\nEs gibt einige Ger\u00e4te auf dem Markt, die im Vergleich zu anderen Ger\u00e4ten vielleicht kosteng\u00fcnstig erscheinen, aber wenn das Ger\u00e4t nicht sowohl den Leiter als auch den Neutralleiter sch\u00fctzt, k\u00f6nnen \u00dcberspannungen in Ihr Eigentum eindringen und das SPD umgehen.\r\n
        \r\n \t
      • Welche Garantie gew\u00e4hrt der Hersteller?<\/li>\r\n<\/ul>\r\nDies ist im Allgemeinen ein wichtiger Indikator f\u00fcr die Qualit\u00e4t der im SPD verwendeten Komponenten.\r\n\r\nKauf des richtigen \u00dcberspannungsschutzger\u00e4ts (SPD).<\/strong>\r\n\r\nW\u00e4hrend jedes SPD den \u00dcberspannungspegel reduziert, der w\u00e4hrend eines \u00dcberspannungsereignisses an elektrische Ger\u00e4te weitergegeben wird, haben einige eine zu hohe Durchlassspannung, um Sch\u00e4den zu verhindern, was fast so ist, als h\u00e4tten sie \u00fcberhaupt keinen Schutz.

Every SPD reduces the surge voltage to equipment during a surge to a voltage tested level known as Let-Through-Voltage.\r\n\r\nTypes of Protection<\/strong>\r\n\r\nWhen discussing di\ufb00erent types of surge protection, there are three main types:\r\n\r\n\r\n\r\n\r\n\r\n\r\n
        Type<\/td>\r\nWhat it does<\/td>\r\nWhere to use it<\/td>\r\n<\/tr>\r\n

          \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.
