Cada SPD reduce la sobretensi\u00f3n del equipo durante una sobretensi\u00f3n a un nivel de voltaje probado conocido como voltaje de paso.\r\n\r\nTipos de protecci\u00f3n<\/strong>\r\n\r\nCuando se habla de diferentes tipos de protecci\u00f3n contra sobretensiones, existen tres tipos principales:\r\n\r\n\r\n\r\n\r\n\r\n\r\n
Tipo<\/td>\r\nque hace<\/td>\r\ndonde usarlo<\/td>\r\n<\/tr>\r\n
Tipo 1<\/td>\r\nProtecci\u00f3n contra rayos directos<\/td>\r\nEn la entrada de red de cualquier instalaci\u00f3n el\u00e9ctrica donde est\u00e9 instalada Protecci\u00f3n exterior contra el Rayo o sea alimentada por l\u00edneas a\u00e9reas.<\/td>\r\n<\/tr>\r\n

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\nC\u00f3mo elegir un dispositivo<\/strong>\r\n

  • \u00bfEs el dispositivo adecuado para su disposici\u00f3n de puesta a tierra?<\/li>\r\n<\/ul>\r\nEste es uno de los problemas m\u00e1s comunes con la instalaci\u00f3n de SPD. La consideraci\u00f3n m\u00e1s importante es para los sistemas TT, donde el dispositivo debe ser adecuado.\r\n

    • \u00bfEl dispositivo protege tanto los polos vivo como neutro?<\/li>\r\n<\/ul>\r\nHay algunos dispositivos en el mercado que pueden parecer econ\u00f3micos en comparaci\u00f3n con otros dispositivos, pero si el dispositivo no protege tanto en vivo como en neutral, las sobretensiones pueden ingresar a su propiedad y pasar por alto el SPD.\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.
