HVD-HVA90 64kV RMS / 90kV Pk AC VLF & 90kV DC High Voltage Tester

The HVA series of universal high voltage test instruments offer unrivalled
power, performance and reliability for the majority of your AC VLF
and DC high voltage testing applications.

While many testing standards around the world have evolved to
recommend the use of AC VLF (Very Low Frequency) rather than DC for
many high voltage testing applications, particularly those involving MV
cables and rotating machines. The HVA Series of instruments include
both high voltage AC and DC outputs to provide the operator with a
single, complete testing package.

The high power HVA90 Test System is capable of testing cables up to 3,300m
(1uF at 0.1 Hz and 64 kV rms).
The variable output frequency allows the testing of even much longer cables.
At 10uF 0.01 Hz and 64 kV rms a length of approx 33,000 m can be tested.
