  • Description

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

    The S-44 VLF 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-24 VLF 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.

    Sonel offers online training course on the use of this product (instructional video and consultation with a specialist).
