2830 / 2831 Precision Oil and Solid Dielectric Analyzer C and tan measurement, DC resistance measurement and relative permittivity r on liquid and solid insulating materials made easy – simple one-time-connection. Large 12” TFT display with touch screen interface and full graphical test visualization Pre-selected oil-testing standards selectable IEC, VDE, BS, ASTM Customized programmable sequence and manual mode Integrated AC power supply 0 – 2’500 V and 40 - 65 Hz adjustable control Integrated DC - Power Supply 250 V - 2.5 kV adjustable 2 independent integrated temperature control units Integrated ambient temperature and humidity sensor Place to connect two oil test cell heater 2903 or one solid test cell 2914 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 , DC resistance and relative permittivity r (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. Existing Tettex test cells 2903 and 2914 can be used Data transfer over USB memory-stick The system consists of 2830, the measuring bridge and control unit, and 2831, the extension unit. This system is a complete replacement of the Tettex 2821 and 2822. Solid materials (Teflon, Silicone, Rubber etc.) The 2830 contains the controller and the measurement part of the system. The 2831 extension unit contains a standard capacitor, 2.5 kV AC & DC supplies and a temperature control unit. APPLICATIONS C and tan measurement and resistance measurement on liquid and solid insulating materials. The 2830 / 2831 is a valuable tool for factory tests, routine tests, R&D tests and regular maintenance. Up to two oil test cells (type 2903) or one solid test cell (type 2914) can be heated at the same time. a brand of Haefely is a subsidiary of Hubbell Incorporated.

2903 Test Cell for Liquid Insulants GENERAL 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 design is according to IEC 60247:2004; ASTM D924-08; ASTM D1169:2002; VDE 0380-2:2005; BS 5737:1979....

2914 Test Cell for Solid Insulants GENERAL The test cell is used for dielectric tests on solid test samples. It determines dissipation factor tan and relative permittivity (dielectric constant) r on solid insulates such as paper and plastic foils, as well as specific resistivity. The test cell is equipped with a shielded measuring electrode (guard ring) which eliminates partial capacitances which influence test results. The design is the result of longstanding experience in the field of test cell building. It has been designed in accordance with specifications of VDE (Germany) & of SEV...
