2903 Test Cell for Liquid Insulants

General Description The precision test cell type 2903 measures the dielectric properties of liquid insulants such as insulating oil, it determines the dissipation factor tan  and the relative permittivity (dielectric constant) r 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 partial 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...
