PDS Partial Discharge
Scanner.
The PDS is used to detect
and locate partial discharges on medium voltage insulated joints, to
monitor their condition while in service or to test for quality, just
after installation.
The PDS indicates the intensity of the partial discharges, converting
the electrical charge units (pC) into decibels (dB). So the reading is
kept as a simple intensity level indication, proportional to the
probability of a fault’s presence in the tested joint.

Insulation
fault detection
Insulation faults are
an important factor in degradation and reduction of lifetime of an
electrical joint.
This translates by raised exploitation costs and questioned reliability,
while economic performance and reliability are key criterions in the
evaluation of an electricity supplier. It is then important that an
electric utility has a wide spread, quick and efficient tool to check
for quality and health of its electrical network.
The market’s demands over electric utilities necessarily transfer to
their subcontractors, who must comply with higher quality requirements
regarding their work. As the electric utility for which he works, the
subcontractor that has tools allowing him to monitor and to certify the
quality of his job will become an attractive and reliable choice.

Safe
manipulations
Easy to use, the PDS can be
handheld or mounted on a two-parts hot stick provided with each unit.
Close-up of the PDS sensor
This insulated and waterproof capacitive probe catches the
electric field sharp variations that characterizes partial discharges.
It integrates both capacitive and inductive sensors,
to allow partial
discharges detection in virtually any cable configuration.
Visual and audio indicators
The visual indicator is a bargraph with eight steps, each step
corresponding to twice the intensity (6dB) of the previous level, for a
total range from 6dB to 48dB. An audio indicator which frequency is proportional
to the displayed intensity allows the user to locate any fault even if
the handling conditions don’t allow him to see the display.
Intensity
level
The PDS indicates the intensity
of the partial discharges, converting the electrical charge units (pC)
into decibels (dB). So the reading is kept as a simple intensity level
indication, proportional to the probability of a fault’s presence in
the tested joint.
