DiAS® 733 Digital Impulse Analyzing System The DiAS®733 is ready for integration in a complete impulse voltage test system. The system can be fully controlled by a host computer via standard interfaces or, to reduce interference effect, via an optical link. Capturing the complete impulse enables to obtain information about the test object faster and in more detail. DiAS®733 is the tool which utilizes latest technology to perform this task. The DiAS®733 is a compact 1- or 2-channel digital impulse analyzing system. Measurement evaluation and analysis of impulse voltages and currents can be performed according to IEC 61083, IEC 60060, IEC 60076, IEC 60099, and IEC 60230, the relevant standards for High Voltage Impulse Testing. Automatic evaluation of the impulse shapes specified in the above standards, as well as a manual evaluation mode are available. Automatic evaluation of all common impulse shapes and their parameters DiAS®733 incorporates many of our own experiences in the high voltage business, plus those of our customers. 128 k memory point depth (for 10 bit data) Impulse voltage tests in industry are mainly used to control the quality of any high voltage equipment. Usually the test object is subjected to a fast voltage impulse. A defined impulse wave shape is applied to the test object according to the relevant standards. Changes in the waveshape caused by the test object are used for detection of insulation faults. This procedure is commonly used for routine testing of transformers, bushings or other high voltage equipment. The DiAS®733 is an excellent and reliable tool for accurate measurement of all kinds of waveshapes. Haefely Test AG also manufacture complete impulse voltage test systems to meet most requirements.

HIGH VOLTAGE TEST MEASUREMENT (DIGITIZING) FEATURES ANALIZING FEATURES 10 bit amplitude resolution. Together with the powerful software analysis tools detailed impulse Variable memory depth up to 128k data points. memory depth allows to choose a suitable record length and helps to avoid unnecessarily large file 100 MS/s and an analogue bandwidth of 30 MHz is fast enough to capture the common impulse shapes in high voltage test labs. High frequency signal components usually have very low amplitudes. High amplitude resolution is therefore critical. The highest bandwidth limit is usually determined...

SYSTEM DESIGN ORDERING INFORMATION DiAS 733System consists of a main unit, containing the system CPU, control computer, power supplies, data storage, interfaces and 2 slots for the exchangeable measuring channel inserts. All accuracy sensitive elements are combined in one small unit per channel. Also supplied are peripheral devices printer, monitor, keyboard and mouse. The advantage of this modular design is that a single measuring channel insert (digitizer) can be easy pulled out and send back for re-calibration while the system works with the other channels. So there is no down time on the...
