SONEL-High Voltage Insulation Tester

SONEL-High Voltage Insulation Tester - FEATURE:

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

  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.

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