  • Test the condition of the cables with VLF or DC slow voltage  

    The S-44VLF high voltage insulation tester is a compact, robust and portable kit for testing medium voltage cables according to IEEE400, IEC 60502-2, CENELEC HD 620 and 621 and DIN VDE 0276/620 and 621. The test is carried out using the low electrical stress method, with a VLF (Very Low Frequency) voltage of 0.1 Hz.

    The VLF test is the fastest way to detect insulation damage. The S-44VLF instrument can test cables with plastic insulation (XLPE, PE-, EPR) as well as paper and oil insulation (PILC). Testing with DC voltage is also possible.

    Evaluate the condition of cables using VLF or DC voltage

    Overview

    The compact, robust and portable cable test set is used for testing of medium voltage cables in accordance to the standards IEEE400, IEC 60502-2, CENELEC HD 620 & 621 and DIN VDE 0276/620 & 621. The test is carried out with a low strain practice with VLF (very low frequency) test voltage at 0.1 Hz frequency.

    VLF test enables detection of damages of the insulation within shortest test time. The S  VLF series device can test cables with extruded insulation (XLPE-, PE-, EPR-insulation) as well as cables with paper-oil insulation (PILC). Cable sheath testing with direct voltage is also possible.

    Optional features

    • Data logging (USB stick) for VLF test sets
    • Frequency extension: 0.05 + 0.02 Hz
    • Customized test cables
    • Transport case
