2903

The precision test cell type 2903 measures the dielectric properties of liquid insulants such
as insulating oil. It determines the capacitance, tangent delta (dissipation factor) & relative
permittivity (dielectric constant) as well as the specific resistivity. The test cell has been
designed as a cylindrical capacitor with a shielded measuring electrode (guard ring
capacitor) & thus avoids stray capacitances which might influence the test results.
The test cell's design is in accordance with the specifications of IEC, ISO, and ASTM
standards (USA).
The complete test cell type 2903 consists of the actual test cell type 2903a as well as the
heating pot 2903h.
