jacket
• Water blocking yarns – to keep water
out
• Woven glass tapes – to give
protection against rodents
• Aramid woven tapes – o ering
ballistic protection

The Tettex 2830/2831 is designed to test
dielectric properties of liquid and solid
insulating materials. It incorporates a
fast and highly advanced procedure
to measure capacitance and tan, DC
resistance and relative permittivity
or (dielectric constant) of liquid or
solid insulating materials. A simple
one-time-connection system together
with resistance measurement according
to pre-selectable standards drastically
reduces measuring time.
The instrument works on the principle
of a combined bridge-vector-meter and
is capable of analysing capacitance and
resistivity on oil and solid insulating
samples with outstanding accuracy
(capacitance 0.2%, tan 1x10-5) and
stability.
The graphical user interface of the
instrument is highly intuitive, is focussed
on convenience with built-in useful
programs and uses a large colour touch
screen as the input device.
While the manual mode provides quick
measurements, the automatic test mode
supports complete programmed and
automated test sequences according to
selectable standards.
Advanced software and hardware
functionalities such as de ning up to
ten cells, heating two test cells at the
same time and graphical visualisation of
measured data make this instrument a
powerful tool for analysis of high-voltage
insulating materials. The instrument
incorporates standard USB and ethernet
interfaces which enable easy exchange of
measurement results, related settings, etc
for further analysis or reporting.
