VLF and DC Hipot Instrument


THE vlf set for 11kV networks.


Find Weak Cables Without Making Cables Weak!

The single piece HVA34 is not only the most advanced high voltage VLF (Very Low Frequency) test system available; it is also the lightest, most compact instrument of its type on the market.

Although primarily designed for the AC Hipot testing of extruded Medium Voltage cable systems - according to the IEEE400 and international testing standards where the application of high voltage DC is no longer recommended - the multi-output HVA34 is also suitable for testing transformers, switchgear, rotating machines and other electrical apparatus.

The instrument offers user programmable 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 (megohm meter) measurements, accurate RMS metering, integrated DUT discharge and reverse voltage/transient protection, all postition this instrument amongst the most sophisticated and easiest to use VLF instrument available.


Optional items include a small portable power pack to supply the HVA30 when a standard 110V/230V AC mains supply is not available. No other VLF unit on the market offers this option!

In addition a portable Tan Delta system (TD30) can be used with the HVA30 for additional cable testing and cable diagnostic capabilities. A full partial discharge system is also possible when used with the new PD30e product.




Smallest, lightest, most advanced universal high voltage test instrument 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 5uF)

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.




Ideal entry level very portable VLF set.

Perfect for systems such as 11kV

1.7Uo capable for up to 24kV networks

3.5Uo capable for up to 11kV networks

Expansion with partial discharge and tan delta accessories
