HIOKI 3455

5kV High Voltage Digital Insulation Resistance Tester Hioki isolator penguji isolasi atau megohmmeter menampilkan desain all-in-one termasuk kasus kasar dan kompartemen penyimpanan timbal. HIOKI 3455 adalah resistansi tahanan isolasi digital 5 range, 250V sampai 5000V dengan bargraf, memori terpasang, pengujian arus dan voltase bocor, dan kemampuan perhitungan DAR dan PI untuk membantu memperpendek waktu kerja yang terkait dengan pengujian isolasi lapangan.
  • Mengukur isolasi peralatan bertegangan tinggi (seperti transformer, kabel, dan motor)
  • Rentang tegangan pengujian yang lebar, sampai 5,00 kV dari 250 V DC
  • Tegangan pengujian yang dapat disesuaikan dalam 25 langkah V sampai 1 kV, dan 100 V langkah dari 1 kV sampai 5 kV
  • Rentang isolasi pengukuran lebar, sampai 5 TΩ (pada tegangan pengujian 5 kV, 1 TΩ = 10 ^ 12 Ω)
  • Mendiagnosa isolasi berbagai peralatan dengan built-in memory untuk penyimpanan data
