The Tettex 2830/2831 is the result of extensive research and years of
experience testing dielectric properties of liquid and solid insulating
materials. It incorporates a fast and highly advanced procedure to
measure Capacitance and tan delta, DC resistance and relative
Ɛr (dielectric constant) of liquid or solid insulating
A simple one-time-connection system together with resistance measurement
according to pre-selected standards drastically reduces measuring time.
The system consists of 2830, the measuring bridge and control unit, and
2831, the extension unit.
The 2830 contains the controller and the measurement part of the system.
The 2831 extension unit contains a standard capacitor, 2.5kV AC and DC
supplies and a Temperature Control Unit. Up to two oil test cells (type
2903 or one solid test cell (type 2914) can be heated at the same time.
