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
        Type 1<\/td>\r\nProtection against direct Lightning strikes<\/td>\r\nAt the mains incomer of any electrical installation where external Lightning Protection is installed, or is fed by overhead lines.<\/td>\r\n<\/tr>\r\n
        Type 2<\/td>\r\nSurge Protection<\/td>\r\nAt the mains incomer of any building that doesn\u2019t need any lightning protection, and for use on any sub boards more than 10-15 meters from the main panel.<\/td>\r\n<\/tr>\r\n
        Type 3<\/td>\r\nEnd equipment protection<\/td>\r\nOn any piece of equipment where a low let through voltage is needed.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nWhat is the correct way to determine which size of SPD to use in a system?<\/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.

          \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.
