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.

FEATURES

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. This
impulse generation capability plus impulse measurement
offers a complete solution to modern testing needs.
