The
total weight for high voltage
filter, coupling capacitor,
calibrator and PD detector for the
partial discharge test is59
kg. Thus the system is
perfectly suitable formobile
use.
For
the partial discharge test a
sinusoidal 0.1 Hz VLF voltage is
employed, adjustable over a range
of up to90
kV peak.
Due
to the following features, the
PD90 is themost
outstandingpartial
discharge test system of its
class:
Measurement
of theintensity
of partial dischargesversus
time
Localization
of faults byTDR(Time
Domain Reflectometry)
Display
of faults in thepartial
discharges mapping

or USB interface to connect PC and
PD Detector
Easy
to use and language selection
The
partial discharge test is
documented in the form of a
ready-to-use report, containing
all relevant results:

Rotating
machines (IEEE 433)
The
PD90 enables any test engineer to
efficiently perform a partial
discharge testwithout
long training periods.
