HVA
30 |
|
 |
The
single piece HVA30 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 is also suitable for testing
transformers, switchgear, rotating
machines and other electrical
apparatus. |

HVA
30.5 |
|
|
The
HVA30 provides the testing
and commissioning engineer
with a versatile high
voltage power source
suitable for testing
electrical plant including
cables: |
|
|
| XLPE,
PE, EPR, PILC etc, capacitors,
switchgear, transformers, rotating
machines, insulators and bushings.
The HVA30/5
provides increased power for the
longer cable runs. |
|
| It
is well known that DC testing of
aged extruded cable such as XLPE
and EPR is potentially damaging to
the cable insulation causing
premature failure of the cable
under service conditions. Any
form of DC testing has been found
to be ineffective in detecting
even serious faults in such
cables. It is because of these
limitations that International and
National bodies such as CENELEC,
VDE, SABS and the IEEE now
recommend testing utilising low
frequency AC test systems. VLF
testing enables the cable test
engineer to detect insulation
defects before the cable fails in
service. |

HVA
60 |
|
|
The
smallest, lightest, most
advanced universal high
voltage test instrument
available, ideally suited
for a variety of
applications. |
|
|
|
The
HVA60 is capable of testing 1µF
(Approx. 10,000 ft/ 3000m of
cable) at 0.1Hz and 60kV peak. The
frequency of the output can also
be reduced allowing even larger
capacitance loads to be tested.
At
0.02Hz, approx. 50,000 ft/15,000m
of cable can be tested.

TD
30 |
|
 |
Tan
Delta testing enables the
cable test engineer to
detect insulation defects
before the cablefails in
service. The TD30
is
a versatile tan delta
measuring system that is
directly connected the HVA
series of VLF test systems. |
|
|
| The
tan delta of the test object can
now be quickly measured and the
results stored thus providing a
“signature” of the device
being tested. This enables the
cable engineer to now make tan
delta routine test. |
