30/40/50/60/70/80 kV Vlf 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.

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:

Specifications:
√ Peak voltage: 80kV
√ Output frequency: 0.1Hz, 0.05Hz and 0.02 Hz (selectable)
√ Fuse: 20A
√ Maximum load capacity: 0.5μF@0.1Hz; 1.0μF@0.05Hz; 2.5μF@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 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).
