Description
KYORITSU KEW 3128 adalah alat ukur resistansi isolasi tegangan tinggi (high voltage insulation tester) yang digunakan untuk menguji kualitas isolasi pada peralatan listrik secara non-destructive. Alat ini mampu menghasilkan tegangan uji tinggi hingga sekitar 12 kV untuk menganalisis kondisi isolasi pada berbagai sistem kelistrikan.
Perangkat ini dikontrol oleh mikroprosesor dan dilengkapi fungsi diagnostik, sehingga dapat mengevaluasi karakteristik isolasi pada kabel, transformator, motor, generator, serta instalasi listrik tegangan tinggi.
FITUR Kyoritsu KEW 3128
- Tegangan uji tinggi hingga 12 kV → cocok untuk pengujian isolasi sistem tegangan tinggi
- Rentang resistansi hingga 35 TΩ → mampu mengukur isolasi dengan nilai sangat besar
