Kapasitas tegangan (kiloVolt \/ kV<\/strong>) pada trafo neon sign<\/em> konvensional, Anda harus menghitung panjang tabung serta berapa sambungan elelktrodanya.<\/p>\n\n\n\n

Jika tegangan trafo terlalu kecil, lampu akan berkedip atau mati total. Jika terlalu besar, tabung kaca akan terlalu panas dan cepat rusak.<\/p>\n\n\n\n

Berikut adalah panduan rumus dan cara menghitung kapasitas kV trafo neon sign<\/em> :<\/p>\n\n\n\n

\n\n\n\n

1. Rumus Dasar Perhitungan Voltase<\/h2>\n\n\n\n

Voltase total yang dibutuhkan oleh satu rangkaian seri neon sign<\/em> dihitung dengan rumus:<\/p>\n\n\n\n

$$\\text{Total Voltase} = (\\text{Total Panjang Tabung dalam Meter} \\times \\text{Volt per Meter}) + (\\text{Jumlah Tabung} \\times \\text{Volt per Pasang Elektroda})$$<\/p>\n\n\n\n

    \n
  • Volt per Meter:<\/strong> Nilai tegangan yang dibutuhkan untuk menyalakan setiap 1 meter tabung kaca. Nilai ini sangat bergantung pada diameter tabung<\/strong> dan jenis gas<\/strong> yang digunakan.<\/li>\n\n\n\n
  • Volt per Pasang Elektroda:<\/strong> Setiap tabung kaca memiliki 2 ujung elektroda. Setiap pasang elektroda membutuhkan tegangan rata-rata 500 Volt<\/strong> hingga 1.000 Volt<\/strong> hanya untuk melompati arus (membuat busur listrik awal).<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    2. Tabel Standar Kebutuhan Tegangan (Referensi Teknisi)<\/h2>\n\n\n\n

    Sebagai acuan standar industri, berikut nilai kebutuhan voltase berdasarkan diameter tabung dan jenis gas (Argon\/Neon) pada suhu normal:<\/p>\n\n\n\n

    Diameter Tabung (mm)<\/th>Kebutuhan Gas Neon (Volt\/Meter)<\/th>Kebutuhan Gas Argon\/Mercury (Volt\/Meter)<\/th><\/tr>
    10 mm<\/strong> (Kecil)<\/td>$\\approx$ 1.100 V \/ meter<\/td>$\\approx$ 850 V \/ meter<\/td><\/tr>
    12 mm<\/strong> (Sedang)<\/td>$\\approx$ 950 V \/ meter<\/td>$\\approx$ 700 V \/ meter<\/td><\/tr>
    15 mm<\/strong> (Besar)<\/td>$\\approx$ 800 V \/ meter<\/td>$\\approx$ 600 V \/ meter<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Catatan: Gas Neon<\/strong> (menghasilkan warna merah\/oranye asli) membutuhkan voltase lebih tinggi daripada gas Argon<\/strong> (warna biru\/hijau\/putih dengan lapisan fosfor).<\/em><\/p>\n\n\n\n

    \n\n\n\n

    3. Contoh Kasus Perhitungan Lapangan<\/h2>\n\n\n\n

    Kasus:<\/strong>
    Anda sedang memperbaiki papan nama hotel yang menggunakan tabung kaca diameter 12 mm<\/strong> dengan gas Neon (Merah)<\/strong>. Rangkaian tersebut terdiri dari 4 huruf terpisah yang disambung seri, dengan total panjang keseluruhan jika dibentangkan adalah 6 meter<\/strong>. Berapa kV trafo yang harus dipasang?<\/p>\n\n\n\n

    Langkah Penyelesaian:<\/strong><\/p>\n\n\n\n

      \n
    1. Hitung Kebutuhan Tabung:<\/strong>
      6 meter $\\times$ 950 Volt\/meter = 5.700 Volt<\/strong><\/li>\n\n\n\n
    2. Hitung Kebutuhan Elektroda:<\/strong>
      Karena ada 4 huruf (4 tabung), berarti ada 4 pasang elektroda.
      4 pasang $\\times$ 500 Volt = 2.000 Volt<\/strong><\/li>\n\n\n\n
    3. Total Kebutuhan:<\/strong>
      5.700 V + 2.000 V = 7.700 Volt<\/strong><\/li>\n<\/ol>\n\n\n\n

      Kesimpulan Pemilihan Trafo:<\/strong>
      Tegangan murni yang dibutuhkan adalah 7.700 Volt (7,7 kV). Di pasaran, trafo diproduksi dalam kelipatan standar seperti 5 kV, 7,5 kV, 9 kV, 12 kV, dan 15 kV.<\/p>\n\n\n\n

        \n
      • Rekomendasi Teknisi:<\/strong> Pilih trafo dengan kapasitas 9 kV (9.000 Volt)<\/strong>.<\/li>\n\n\n\n
      • Alasan:<\/em> Teknisi wajib memberikan faktor keamanan (safety margin<\/em>) sebesar 15% – 20%<\/strong> di atas hitungan murni untuk mengantisipasi penurunan tegangan PLN atau cuaca dingin\/lembab di gedung tinggi yang meningkatkan hambatan listrik.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        4. Tips Penting <\/h2>\n\n\n\n
          \n
        • Jangan Overload:<\/strong> Jangan memaksa satu trafo memikul panjang tabung yang melebihi kapasitas kV-nya. Jika total hitungan Anda adalah 14 kV, gunakan trafo 15 kV, atau bagi rangkaian tersebut menjadi dua jalur mandiri menggunakan dua trafo 7,5 kV.<\/li>\n\n\n\n
        • Periksa Arus (mA):<\/strong> Selain kV (tegangan), trafo neon juga memiliki spesifikasi miliAmpere (mA), biasanya 30mA, 45mA, atau 60mA. Pastikan mA trafo baru sama dengan trafo lama agar kecerahan lampu seragam dengan huruf lainnya.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
