Haefely DDX 9101 Overview

The DDX 9101 partial discharge detector comes from the very successful family of DDX detectors. It is the ideal solution for pass/fail partial discharge testing; incorporating all the basic functions of an analog detector and meets all IEC and IEEE/ANSI standards for PD testing. We’ve eliminated the costly advanced features associated with fully computerized PD detectors. The DDX9101 simply measures the level of PD and the applied test voltage. It’s designed to help you modernize your facility at an affordable price, and it’s simple to operate.

The DDX9101 a straightforward replacement for older analog detectors of any make or model. The system is housed in a 3U 19” rack mount case designed to slide into a rack cabinet. Or, if you need a complete new test system, the detector can be integrated into an AC power supply for production PD testing of HV components.

This simple-to-use detector is controlled via 8 control buttons on the front panel. To operate the detector, select the desired operation mode (magnitude meter or oscilloscope mode) and choose the appropriate amplifier settings. Calibrate the measurement setup, set the maximum acceptable PD level and you are ready to start the test. Once voltage is applied to the test object, an indicator on the screen tells you if the test object passes or fails the test.

With the data acquisition / remote control software and a PC (optional) the capabilities of the unit are greatly expanded. All data is acquired during the test according to user-defined parameters, the data can then be used to generate customized test reports with graphs and charts. The user can also take “snapshots” of the ellipse any time during a test. It’s just like that camera on your old analog scope, only easier.

The most distinguishing feature of the DDX9101 advanced software is its ability to operate and monitor multiple detectors simultaneously. If you are a manufacturer performing routine PD tests in multiple bays, each DDX9101 can now be linked to a single PC enabling remote controls, monitoring and acquisition of all data.

Features:

• Settable PD threshold with indicator light when limit is exceeded
• Ethernet port for communication with a PC (optional)
• Data acquisition and remote control software package
• Two modes of operation - meter mode or scope mode
• Compact, 3U (19”) rack mount case is ideal for integrating into a test system
