Sonel High Voltage VLF and DC Tester
The compact, robust and portable cable test set high voltage VLF and DC testers 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 high voltage VLF and DC testers 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.
