VLF AC HIPOT TEST SET
EPVLF-80/1.1
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.
