Atec Tettex-2883 - Manual (Page 2)

2 / 4
ONE BOX – RUGGED AND EASY TO
TRANSPORT
The complete instrument is built in one ruggedized
case and has a total weight of only 25 kg / 55 lb. With
the integrated casters transportation
is convenient and test objects in
remote locations can be reached
easily.
The MIDAS micro 2883 has run
through extensive type testing to
simulate the rough environment a
product can face during its
lifetime. Fulfilling the MIL-STD-
810G standard, MIDAS micro
2883 assures you the highest
quality and reliability in
operation.
Included are a variety of
accessories all packed in a
robust transportation bag which
can be attached to the case.
The measurement and high voltage
cables are rolled on cable drums which make
connection and storing convenient and quick.
RELIABLE RESULTS - ALWAYS
Accurate measurements in substations can be difficult
because of strong electrical fields generated by high
voltage transmission lines. The MIDAS micro detects
that interference is present and switches to the
appropriate noise suppression mode, if necessary.
State-of-the-art digital signal processing is used to filter
out the interfering signals. This results in stable and
repeatable values under all conditions.
SAFE OPERATION
The MIDAS micro 2883 includes several features that
ensure safety of the personnel and material. It is
equipped with an open ground detection which allows
high voltage to be switched on only when a proper
ground connection has been made to the unit. In
addition to an emergency stop button, the unit is
equipped with an external dead-man type safety switch
which must be held down prior to testing to allow for
high voltage to be turned on. The warning sound and a
warning lamp bar located on the top side of the display
provide visual and audible warning signals. Additionally
an external optional strobe light can be connected.
THE FEATURES YOU NEED
The instrument includes all the features needed to perform
tests on various high voltage components. The 12 kV
voltage source delivers a clean signal, independent of the
mains. The variable frequency source (15 – 400 Hz)
allows for advanced measurements such as bushing
analysis over a frequency range. A gas filled standard
capacitor is used as an internal reference. This
guarantees repeatable results and long term stability. With
the USB interface and integrated thermal printer, reporting
of results is easy.
QUICKLY TO THE RESULTS YOU WANT
Three operating modes
are built in, to suit your
needs. Use the basic
mode for quick and
straight forward
measurements where
only essential displays
and controls are shown.
Or allow the Guide Mode to
walk you through the
measurements - from basic insulation diagnosis to
advanced tip-up and variable frequency bushing analysis.
The advanced mode offers even greater flexibility for
special test sequences.
THE PERFECT COUPLE FOR TRANSFORMER
TESTING
Combine the MIDAS micro 2883 with the Winding
Analyzer 2293 for an entire test solution on transformers.
With 2293 tests like winding resistance, transformer turns
ratio and magnetic balance measurements can be done
with one single connection. Compatible file formats allow
data exchange between the two units and measurements
results are combined for further analysis or processing.
