VLF and DC Hipot Instrument


HVA94 brings 66kV cable testing in house!


Find Weak Cables Without Making Cables Weak!

The single piece HVA90 and HVA94 are not only the most advanced high voltage VLF (Very Low Frequency) test systems of their kind available; they are also the lightest, most compact instruments of their type on the market.

Although primarily designed for the AC Hipot testing of extruded medium voltage cable systems - (according to the new IEEE400 and international testing standards where the application of high voltage DC is no longer recommended) - the multi-output HVA90 series are also suitable for testing transformers, switchgear, rotating machines and other electrical apparatus.

The instruments offer fully automatic testing sequences which allow the operator to effortlessly apply the correct testing standards without having to remember what those testing parameters are, thus avoiding possible over stressing of the cable system.


Standard features like built in storage of test results, smooth load independent and symmetrical Sinewave HV outputs, DC and AC VLF outputs, capacitance and insulation resistance (mega-ohmmeter) measurements, accurate RMS metering, integrated discharge and transient protection, all make these instruments the most sophisticated and easiest to use VLF test sets available.


There really is no other product in the world that competes with the combination of small size low weight and high performance offered by these units. The HVA94 allows the user to run a true 1.7Uo test on a 66kV cable!


In addition a portable Tan Delta system can be used with the HVA90 or HVA94 for additional cable testing and cable diagnostic capabilities.




Smallest, lightest, most advanced universal high voltage test instruments available.

VLF (0.1Hz), DC (+/-), Cable Fault Conditioning (Burning), and Sheath/Jacket Testing modes all included.

Fully Automatic or manual cable test sequences

True Symmetrical Sinusoidal, load independent, output waveform across the full load range.

Real-time oscilloscope display of actual output waveform

Easy to use, ergonomic, menu guided, large backlit user interface

Rugged, one-piece design for easy portability

Large output load capability (up to 10uF)

Automatic and integrated load capacitance measurement with optimum frequency selection.

Integrated memory for storage of test results that can be downloaded to a PC/laptop at a later time.

No oil filled components or arcing contacts that require routine maintenance

Short circuited protected with active arc management regulation that avoids the usual nuisance tripping of conventional HV test equipment when a dielectric failure occurs.
