Multichannel PD Detector / RIV

More Information

Overview

The DDX 9121b is the latest in the DDX family for  partial discharge & radio interference voltage testing.  With the DDX 9121b, users can control, test, monitor  and generate test reports from a single computer.

  • AC and DC measuring modes
  • Data acquisition and test report generation.
  • Embedded switch with four PD inputs per detector.
  • High resolution spectrum analyzer with oscilloscope.
  • Modular design, 1 to 9 detectors- easily upgradable.
  • PD patterns like Φ-q-n (phase, magnitude, occurrence)
  • PD Site Location (SL) on cables
  • Simultaneous RIV and PD reading.
  • User defined measuring band

  • Reduces ground noise - The built in frequency spectrum analysis and selectable frequency band let the user optimize the setup in seconds.
  • Optimizes investment if needs change. Unit can be easily upgraded (RIV, 4 inputs switch, simultaneous PD readings, PD on DC, etc.)
  • Reduces 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 quadruple and installing the DDX 9121b.
  • 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.
