More Information

Overview

The Dielectric-Loss Analyzing System 2820a is designed for measurement of low dielectric losses and impedances (Dissipation Factor and Power Factor) of high-voltage apparatus (e.g. the insulation of bushings).The instrument works on the principle of a combined bridge-vector-meter and is capable of analyzing capacitive and inductive loads with high accuracy and stability.The Graphical User Interface of the instrument is highly intuitive, is focused on convenience with built-in useful programs (e.g. support tool for tuning the external high-voltage supply) and uses a large colour touch screen as the input device.

  • Accuracy capacitance 0.02%, tanÂ&
  • nbsp
  • d 1x10-4
  • Additional signal analysis capabilities like Spectrum Analyser, Digital Scope and Data Logger are integrated
  • Advanced, well-engineered test equipment, optimized to the specific application
  • Compact, reliable and EMC hardened design
  • Integrated solution with built-in industrial computer

  • Easy to operate with manual and automated test modes, software assisted test preparation, execution and trend analysis.
  • Complete Measuring System including power supplies, standard capacitors, current comparators, test cells, application support and calibration from one supplier.
  • Wide Application Range. Losses of all types of insulation including shunt reactors under unstable power frequency can be measured.
  • Upgrade - Outdated Tettex bridge models (e.g. 2877, 2801, 2821, etc.) can be easily replaced, with existing cable sets.
