Schneider SAMWHA EOCR ISEM Series

Electronic Over Current Relay (EOCR) seri ISEM merupakan EOCR terbaru yang di produksi oleh Schneider Electric di Korea, dengan membawa berbagai keunggulan dan fitur baru.

Fitur

  • Monitor daya aktif / reaktif dan listrik (terintegrasi)
  • Merekam gelombang kesalahan (200 ms); Merekam arus 3 fase dan tegangan 3 fase, dan menyimpan data
  • Mengukur energi listrik melalui kontak keluaran 4-20 mA (+, -)
  • Pemeriksaan status isolasi motor: Dapat memilih dari resistansi isolasi standar 1 MΩ, 5 MΩ, dan 10 MΩ, dan mendiagnosis jika lebih tinggi atau lebih rendah dari nilai referensi (dapat didiagnosis saat motor berhenti berjalan)
  • Pengukuran arus 3 fase: 0,5 ~ 100A dengan penggunaan built-in CT, 100 ~ 960A dengan penggunaan CT eksternal
  • Mengizinkan earth fault protection dengan ZCT bawaan tanpa harus terhubung ke ZCT eksternal (0,03 ~ 10A)
  • Tanggal dan waktu dapat diperiksa selama listrik padam dengan pengaturan Tanggal / Waktu (y / m / d / h / m / s)
  • Berbagai metode perlindungan: Definite, Inverse, dan Thermal Inverse
  • Melindungi terhadap earth fault current dan korsleting secara bersamaan (50 msec)
  • Fungsi komunikasi: MODBUS RS-485
  • Merekam informasi dari 3 kesalahan terakhir: Jenis kesalahan, arus gangguan, dan tanggal / waktu kesalahan
  • Fungsi pengaturan keamanan (fungsi password)
  • Fungsi tampilan Grafik Batang: Mampu memeriksa rasio arus operasi vs set current.
  • Restart Limit Function pengaturan waktu operasi dan tampilan.
  • Menyediakan software yang memungkinkan operator melakukan pengaturan dan pemantauan melalui PC.
