Description

EP Hipot Electric EPVLF Portable VLF cable testing system Output voltage 34kV 35kg


General Information:
VLF stands for Very Low Frequency. VLF is generally considered to be 0.1 Hz and lower, its major application is for testing solid dielectric cable, transformers, motors, generators, switchgear, and other electrical apparatus.

A VLF hipot is just an AC output tester but with an output frequency of 0.1 Hz or lower rather than 50/60Hz. Although the frequency is very low, it is still an alternating current with polarity reversals every half cycle. At 0.1 Hz output, rather than 60Hz, it takes 600 times less current and power to apply an AC voltage to a capacitive load, like a long cable.


Feature:
  • Adapts microprocessor controlled, can realize voltage set-up/down, measuring and protecting automatically. Manual intervention is allowable even during the auto voltage boosting.
  • Touch screen, large LCD can display waveform clearly, and test report can be printed. Built-in printer
  • Multiple protections (overvoltage protection, overcurrent protection at HV/LV sides). When the output is beyond the limitation, the control unit will shut itself down within 10ms.
  • Easy operation: simple wiring and operation.
  • Safe and reliable: the controller and the high-voltage generator are connected at low voltage, photoelectrically controlled, safe and reliable to use.
  • Closed-loop negative feedback circuit is adopted. No capacity rising during outputting.
  • Large test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, large test range.
  • Portable design, small size and light weight: it is very convenient for outdoor operation.
