Vlf 80kv Very Low Frequency AC Hipot Test Set
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.
Features:
√ 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.
√ Portable, easy to move.
√ Large LCD can display waveform clearly, and test report can be printed. Built-in printer.
√ Adapts microprocessor controlled, can realize voltage set-up/down, measuring and protecting automatically. Manual intervention is allowable even during the auto voltage boosting.
√ The data of current, voltage, and waveform can be sampled at HV side.
√ Over voltage and current protection: When the output is beyond the limitation, the control unit will shut itself down within 20ms.
Specifications:
√ Peak voltage: 80kV
√ Output frequency: 0.1Hz, 0.05Hz and 0.02 Hz (selectable)
√ Voltage waveform distortion: ≤5%.
√ 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%.
√ Working environment: indoor or outdoor; -10ºC-+50ºC; 85%RH.
