The High-Precision Dielectric-Loss Analyzing System 2823 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 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 personnel the highest safety level.

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: High Precision Current Comparator 400 A

The high precision Current Comparators (current transformers) are used to convert high currents to a lower, measureable level.
