HiAS® 743
High Resolution Impulse Analyzing System
Capturing the complete impulse enables to obtain
information about the test object faster and in more detail.
HiAS®743 is the tool, which utilizes latest technology high
amplitude and fast time resolution to perform this task.
The HiAS®743 is a multi-channel precision digital impulse
analyzing system of the highest performance class.
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.
The HiAS®743 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
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.
Changes in the wave-shape 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 HiAS®743 is
an excellent and reliable tool for accurate measurement of
all kinds of wave-shapes. Haefely Test AG also manufactures
complete impulse voltage test systems to meet most
requirements. This impulse generation capability plus
impulse measurement offers a complete solution to modern
testing needs.
HiAS®743 incorporates many of our own experiences in the
high voltage business, plus those of our customers.
Since many years our R&D group continuously develops
further the system software. Therefore this system has the
most proven software in the market. Curve evaluation for
example is based on databank containing hundreds of real
curve data, measured in different environment and test
setups all over the world.
