High Voltage Insulation HiTESTER (Hioki 3455)

The HIGH VOLTAGE INSULATION HiTESTER 3455 is made for measuring insulation resistance in high-voltage facilities.


The instrument's powerful features include the ability to change the settings in fine steps over a wide range of voltages, and an assortment of other functions necessary for a variety of diagnostic requirements. The 3455 is packed in a compact body and offers ease of use. Careful consideration has been made in regards to safety in the design, making the instrument compatible to use almost anywhere.


  • Measure insulation of high-voltage equipment (such as transformers, cables, and motors).

  • Wide testing voltage range, up to 5.00 kV from 250 V DC.

  • Adjustable testing voltage in 25 V steps up to 1 kV, and 100 V steps from 1 kV to 5 kV.

  • Wide measurement insulation range, up to 5 T次 (at 5 kV testing voltage, 1 T次=1012 次).

  • Diagnose the insulation of various equipment with the built-in memory for data storage.
