Product Description
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.

Features:
√  Adapts microprocessor controlled, can realize voltage set-up/down, measuring and protecting automatically. Manual intervention is allowable even during the auto voltage boosting.
√  Portable, easy to move.
√  Large LCD can display waveform clearly, and test report can be printed. Built-in printer.
√  The data of current, voltage, and waveform can be sampled at HV side. 
√  A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside.
√  Closed-loop negative feedback circuit is adopted. No capacity rising during outputting.
√  Over voltage and current protection: When the output is beyond the limitation, the control unit will shut itself down within 20ms.
 
Specifications:
√   Peak voltage: 30kV
√   Output frequency: 0.1Hz, 0.05Hz and 0.02 Hz (selectable)
√   Fuse: 10A
√   Maximum load capacity: 1.1μF@0.1Hz; 2.2μF@0.05Hz; 5.5μF@0.02Hz
√   Power supply: 220V ±10%, 50Hz ±5% (If using a portable generator, make sure the output voltage and frequency are stable. Power >3kW. Power supply @ 110V 60Hz is optional)
√   Output voltage accuracy: peak voltage instability ≤1%; frequency instability ≤3%.
√   Voltage waveform distortion: ≤5%.
√   Working environment:       indoor or outdoor; -10ºC-+50ºC; 85%RH.
√   Weight: Control unit - 4kg; HV unit: 25kg.

Warranty: One year quality guarantee after shipment.
