Catalog ID: 2914 Solid Test Cell

The 2914 test cell measures dissipation factor, relative permittivity, and specific resistivity of solid insulating materials such as paper and plastic foils.The test cell is equipped with a shielded measuring electrode which eliminates partial capacitances that influence test results.

Catalog ID: 2903 Oil Test Cell

The precision test cell type 2903 measures the dielectric properties of liquid insulants such as insulating oil, it determines the dissipation factor tan delta 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.

Catalog ID: 5288a

The capacitive load range of the MIDAS System can be increased by using this Compensator Reactor (resonating inductor).The 5288a provides a manual tunable 12 kV, 40 kVA inductor coil. It comes into use mainly for power generator or other high capacitive loads on on-site testing.

Catalog ID: 4762 Range Extender, 400A

This electronically controlled current transformer is specifically designed for current range extension in capacitance measurements. It has divider ranges of 1:10 and 1:100.The special transformer is accommodated inside a portable casing with all terminals on the top panel.

Catalog ID: MIDAS micro 2883

The MIDAS micro 2883 is a revolutionary C & Tan Delta / Power Factor / Dissipation Factor tester used to test the insulation of high voltage components (i.e. transformers, bushings, capacitors and so on). Designed and tested for all types of conditions, the complete instrument is built in one rugged case with casters.With its single-box design, weighing only 25 kg / 55 lbs, this tool can be easily transported to any testing location – in the field or in the factory. All accessories are stored in a robust duffel bag that can be affixed to

Catalog ID: MIDAS 2881

The MIDAS 2881 is a portable power factor tester for periodic maintenance and inspection of high voltage insulation losses of electrical apparatus, especially in the harsh electrical environments experience in substations and other field locations.Designed for testing at local power-line frequency, the MIDAS automatically measures and records dissipation factor (tan d), power factor (cos F) and all other relevant values of impedances. Damage or changes in the insulation material are detected rapidly and reliably.

Catalog ID: 2823-REF

The High-Precision Dielectric-Loss Analyzing System 2823-REF is designed for measurement of very low dielectric losses and impedances (Dissipation Factor and Power Factor) of high-voltage apparatus (e.g. extruded insulation on power cables). The instrument works on the principle of a combined bridge-vector-meter and it is capable of analyzing capacitive and inductive loads – especially shunt reactors – with outstanding accuracy and stability certified by a leading metrology institute.The use of optically decoupled connection allows complete galvanic isolation between control room and test field, and guarantees the highest safety level to the personnel.

Catalog ID: 2830 / 2831

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 er (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.
