60KV 80KV Ultra Low Frequency 0.05Hz VLF Hipot Tester high voltage generator withstand tester
Bangzhao BVLF stands for Very Low Frequency. A Bangzhao BVLF is an AC output high voltage instrument. Bangzhao BVLF products provide sinusoidal AC voltage but at 0.1Hz - 0.02 Hz, compared to the 50/60Hz output of conventional AC test sets. It is still an AC voltage with sinusoidal polarity reversals every half cycle. The Bangzhao BVLF instrument is used to provide a simple go/no-go, or pass/fail withstand test. Also, Bangzhao BVLF instruments can be used as the voltage source for performing off-line Partial Discharge testing.
