The compact, robust and portable cable test set S-36 VLF is used for testing of medium voltage cables in accordance to the standards IEEE400, IEC 0502-2, 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 of preferably 0.1 Hz. VLF Test enables detection of damages of the insulation within shortest test time. The S-36 VLF 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.
