Setiap SPD mengurangi tegangan lonjakan ke peralatan selama lonjakan ke tingkat tegangan yang diuji yang dikenal sebagai Let-Through-Voltage.\r\n\r\nJenis Perlindungan<\/strong>\r\n\r\nSaat membahas berbagai jenis proteksi lonjakan arus, ada tiga jenis utama:\r\n\r\n\r\n\r\n\r\n\r\n\r\n
Jenis<\/td>\r\nApa fungsinya<\/td>\r\nDi mana menggunakannya<\/td>\r\n<\/tr>\r\n
Tipe 1<\/td>\r\nPerlindungan terhadap sambaran petir langsung<\/td>\r\nPada sumber listrik dari instalasi listrik mana pun yang dilengkapi dengan Penangkal Petir eksternal, atau disuplai melalui saluran udara.<\/td>\r\n<\/tr>\r\n
Tipe 2<\/td>\r\nPerlindungan Lonjakan<\/td>\r\nDi bagian utama bangunan mana pun yang tidak memerlukan proteksi petir, dan untuk digunakan pada sub-papan apa pun yang berjarak lebih dari 10-15 meter dari panel utama.<\/td>\r\n<\/tr>\r\n
Tipe 3<\/td>\r\nAkhiri perlindungan peralatan<\/td>\r\nPada peralatan apa pun yang memerlukan tegangan tembus rendah.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nApa cara yang benar untuk menentukan ukuran SPD yang akan digunakan dalam suatu sistem?<\/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\nCara memilih perangkat<\/strong>\r\n
    \r\n \t
  • Apakah perangkat ini cocok untuk pengaturan pembumian Anda?<\/li>\r\n<\/ul>\r\nIni adalah salah satu masalah paling umum pada instalasi SPD. Pertimbangan paling penting adalah untuk sistem TT, di mana perangkat harus sesuai.\r\n
      \r\n \t
    • Apakah perangkat melindungi kutub aktif dan netral?<\/li>\r\n<\/ul>\r\nAda beberapa perangkat di pasaran yang mungkin terlihat murah dibandingkan perangkat lain, namun jika perangkat tidak melindungi arus listrik dan netral, lonjakan arus dapat masuk ke properti Anda dan melewati SPD.\r\n
        \r\n \t
      • Garansi apa yang diberikan pabrikan?<\/li>\r\n<\/ul>\r\nIni umumnya merupakan indikator kunci kualitas komponen yang digunakan dalam SPD.\r\n\r\nMembeli Alat Pelindung Lonjakan Arus (SPD) yang Tepat.<\/strong>\r\n\r\nMeskipun SPD apa pun akan mengurangi tingkat tegangan lonjakan yang diteruskan ke peralatan listrik selama terjadi lonjakan arus, beberapa SPD memiliki Tegangan Let-Through yang terlalu tinggi untuk mencegah kerusakan, yang hampir sama dengan tidak memiliki perlindungan sama sekali. BRITEC menawarkan rangkaian lengkap perangkat pelindung lonjakan arus untuk melindungi peralatan listrik. Perangkat Pelindung Lonjakan Arus BRITEC adalah pilihan tepat untuk semua bisnis dan rumah.","protected":false},"featured_media":870,"parent":0,"menu_order":143,"template":"","meta":{"_acf_changed":false},"blog_category":[8],"class_list":["post-868","blog","type-blog","status-publish","has-post-thumbnail","hentry","blog_category-company-news"],"acf":{"des":"A Surge Protective Device (SPD) is designed to reduce surge voltage, which protects equipment and reduces repair and replacement costs.

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. BRITEC offers a complete range of surge protective devices to protect electrical equipment.
