VLF and DC Hipot Instrument


Heavy duty VLF set for large and long cables.


Find Weak Cables Without Making Cables Weak!

The single piece HVA30-5 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 new IEEE400 and international testing standards where the application of high voltage DC is no longer recommended - the multi-output HVA30-5 is also suitable for testing transformers, switchgear, rotating machines and other electrical apparatus.

The instrument offers 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 this instrument the most sophisticated and easiest to use VLF instrument available.


Optional items include a small portable power pack to supply the HVA30-5 when a standard 110V AC mains supply is not available. No other VLF unit on the market offers this option!

In addition a portable Tan Delta system can be used with the HVA30-5 for additional cable testing and cable diagnostic capabilities.




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.


The HVA30-5 is really a special version of the HVA30 which is much uprated in power. This is specifically for testing cables of very long length (and therefore of very high capacitance). See data sheet for details.
