Vlf 80kv AC Hipot Test Equipment 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:
1. Adapts microprocessor controlled, can realize voltage set-up/down, measuring and protecting automatically. Manual intervention is allowable even during the auto voltage boosting.
2. The data of current, voltage, and waveform can be sampled at HV
side.
3. Closed-loop negative feedback circuit is adopted. No capacity
rising during outputting.
4. Portable, easy to move.
5. 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.
6. Large LCD can display waveform clearly, and test report can be
printed. Built-in printer.
7. Over voltage and current protection: When the output is beyond the limitation, the control unit will shut itself down within 20ms.
Specifications
1. Peak voltage: 80kV
2. Fuse: 20A
3. Output frequency: 0.1Hz, 0.05Hz and 0.02 Hz (selectable)
4. Maximum load capacity: 0.5μF@0.1Hz; 1.0μF@0.05Hz; 2.5μF@0.02Hz
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)
6. Output voltage accuracy: peak voltage instability ≤1%; frequency
instability ≤3%.
7. Voltage waveform distortion: ≤5%.
8. Working environment: indoor or outdoor; -10ºC-+50ºC; 85%RH.
9. Weight: Control unit - 4kg; HV unit I: 25kg; HV unit II:
45kg.
Remarks: Capacitance of test object cannot be larger than the
maximum value of the test instrument. If capacitance of test object
is smaller than 0.05μF, the hipot should be equipped with an
auxiliary device (supplied by Sansion Power Electric at your
option).
