The HVA30 is the most advanced HV test
system available, it is also the lightest,
most compact instrument of its type on the
market. The HVA30 has the highest power to weight ratio of any
comparable unit available.
There is no need to carry two pieces of equipment around and
then interconnect them!
Apart from the variable frequency VLF output, the operator can
also select dual polarity DC and cable jacket or sheath testing
output modes.
The applied test voltage, current, capacitance, resistance and
time are displayed and recorded.
The instrument is easily programmable allowing the operator
to setup or select test sequences in either automatic or manual
mode.
The HVA30 is capable of testing 0.5μF (Approx. 1500m /
5,000ft of cable) at 0.1Hz and 23kV rms. The frequency of the
output can also be reduced allowing even larger capacitance

loads to be tested. At 0.02Hz, approx. 7620m / 25,000ft of
cable can be tested.
To assist the operator, the instrument will automatically
calculate the optimum frequency to be selected for larger
loads.
The load independent, symmetrical output waveform avoids
the potentially destructive space charge effects caused by DC
polarization that occurs in aged extruded cables such as XLPE
/ PE / EPR, causing them to fail prematurely when exposed to
conventional high voltage DC or from a test instrument with
large non-symmetrical output waveforms.
Should a breakdown occur during testing, the actual voltage
at which it occurred is displayed and recorded. If cable burning
(fault conditioning) mode is activated, the fault resistance can
be conditioned to allow easier and less stressful fault location
techniques to be applied.
The results are stored in the instrument’s onboard memory
allowing easy retrieval and download to a PC or USB drive.
