DDX 9121B
Modular Partial Discharge (PD) & Radio Interference Voltage (RIV) Detector
The DDX 9121b is the latest in the DDX family for partial
discharge & radio interference voltage testing. With the
DDX 9121b you can setup, control, test, monitor and
generate test reports from a single computer.
Its modular design makes the DDX9121b flexible for any
application. From single measuring input to simultaneous 9
measuring inputs. From traditional partial discharge
according IEC60270 to RIV measurement or PD under DC.
From pass/fail test to advance phase resolution time
analysis. The DDX9121b includes all you need, and have all
you want.
The DDX 9121B comprises 1 to 9 rack-mounted unit(s)
communicating with a remote PC (not included), which
handles the display of PD information using the DDX
9121b/SWR data acquisition and remote control software.
The software displays test results, generates test reports,
and provides a means to calibrate the system.
Digital filters allow the measurement frequency range to be
at any range into the measuring band to suppress
frequency dependent noise. In addition gating possibilities
allow blanking out stationary interferences.
The reports can then be printed out from the software or
displayed as a web page. With help of the software the
user can also export the results for use in a spreadsheet.
Software also provides bitmaps for inclusion in other
reports.
FEATURES
 User defined measuring band.
 Modular design, 1 to 9 detectors, easily upgradable.
 Embedded switch with four PD inputs per detector.
 Simultaneous RIV and PD reading.
 PD patterns like φ  -q-n ( phase, magnitude, occurrence)
 High resolution spectrum analyzer with oscilloscope.
 Data acquisition and test report generation.
 AC and DC measuring modes
BENEFITS
Reduce your ground noise –The built in frequency
spectrum analysis and selectable frequency band let you
optimize your setup in seconds.
Optimize your investment if your needs change. Unit can
be easily upgraded (RIV, 4 inputs switch, simultaneous PD
readings, PD on DC…)
Reduce your training time –The Windows based software
makes the use of the device easier than ever. Operators can
start using the device in minutes.
Straightforward replacement –replacement is as simple as
removing the obsolete PD detector and measuring
quadripole and installing the DDX9121b.
PD interpretation – The phase resolved analysis and
recording capabilities allow for future data analysis .
Easy to integrate into test systems – Its compact design
standard BNC measuring cables and remote control
capabilities make it ideal for an integrated PD test system
together with an AC power supply.
APPLICATIONS
Testing of:
 Power and distribution transformers
 Instrument Transformers
 Rotating Machines
 Power Capacitors
 Switchgears
 Surge Arrestors
 Research & Development
