2830/2831 Oil and Solid Dielectric Analyzer - Overview

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 permittivity Ɛr (dielectric constant) of liquid or solid insulating materials.

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.
