Analyzing System Measures Very Low Dielectric Losses

The Tettex Dielectric-Loss Analyzing System 2840 from Hipotronics 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 ¡V especially shunt reactors ¡V with accuracy (capacitance 0.02%, tan £_ƒn1x10-5) and stability.

The Graphical User Interface of the instrument is highly intuitive, is focused on convenience with built-in useful programs and uses a large color touchscreen as the input device.

While the manual mode provides quick measurements, the automatic test mode supports complete automated test sequences.

Advanced software functionalities such as insulation temperature correction, programmable test sequences with pass/fail limits, graphical visualisation of measured data, etc. make this instrument a powerful tool for analysis of high-voltage equipment.

The instrument incorporates standard interfaces (e.g. USB) which enable easy exchange of measurement results, related settings, etc. for further analysis or reporting.
