The smallest, lightest, most advanced universal high voltage
test instrument available, ideally suited for a variety of ap-
plications.
VLF (0.1Hz), DC (±), Cable Fault Conditioning (Burning), and
Sheath/Jacket Testing modes all included.
VLF: the proven and accepted replacement for the traditional
DC Hipot or “proof” test for solid dielectric cables such as
XLPE and EPR.
Fully automatic or manual cable test sequences complying
with International Standards/Guides such as IEEE 400.2, VDE
0276, CENELEC, HD620 S1, NEN 3620, SANS 10198 and IEC
60060-3.
Meets all your cable testing requirements.

form across the full load range.
Real-time Display of actual output wave form.
Easy to use, ergonomic, menu guided, large backlit user
interface.
Rugged, one piece portability.
Large output load capability (up to 12μF)
Automatic and integrated load capacitance measurement
with optimum frequency selection.
Storage of test results for later retrieval or download to a
PC/Laptop.
No oil or arcing contacts that require routine maintenance.
Short circuit protected with active arc management regula-
tion that avoids the tripping of conventional HV test equip-
ment when a dielectric failure occurs.

OPERATIONAL FEATURES
It is well known that DC “proof” (or hipot) 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. Space charges that develop during DC testing present potential
safety hazards to operators and may damage the cable or attached equipment if not discharged correctly.
In addition, DC testing has been found to be ineffective in detecting all but the most serious defects in cables.
Acceptance or maintenance hipot/proof testing using VLF high voltage sinusoidal AC allows the operator to effi ciently detect serious cable
insulation defects, before they result in an in-service failure, without affecting those healthy sections of the cable that still have remaining
service life.
Sinusoidal VLF testing can support effective dielectric diagnostic measurements that are not possible with DC voltages.
