DDX 7000 and 8003 Advanced Partial Discharge Detector with Cable Fault Location - Overview

Overview
The Haefely Hipotronics DDX® Digital Partial Discharge Detector offers the high accuracy and flexibility of digital technology, plus the real-time display and easy operation of an analog instrument. It is everything you want in a digital system with everything you know from an analog system...truly the best of both worlds.

The DDX® Detector provides the most intuitive and easiest to use operator interface of any available digital PD testing system. Data analysis is fast, easy and requires little training. It's Windows™ based software allows flexible test recording and data export to Word™, Excel™, and other Windows programs. In addition, only the DDX® Detector provides a completely open-architecture hardware and software solution through the use of the fastest processors, Microsoft Windows and Microsoft ActiveX™ technology.

The Haefely Hipotronics DDX® Detector can also automate your entire PD testing process, from voltage source control to calibration to test report generation. They offer three different models, each aimed at satisfying specific customer needs:

  • DDX 7000 with robust partial discharge analysis software.

  • DDX 7000 SL with advanced partial discharge site location software geared towards power cable manufacturers.

  • DDX 8003 which offers sophisticated noise suppression technology with the incorporation of additional hardware.
