2840 High Precision Power Factor Tester





The Dielectric-Loss Analyzing System 2840 is a power factor tester designed for measurement of very low dielectric losses and impedances (Dissipation Factor and Power Factor) of high voltage apparatus. The instrument works on the principal of a combined bridge-vector-meter and is capable of analyzing capacitance and inductive loads with outstanding accuracy and stability certified by leading metrology institutions.




  • Accuracy capacitance 0.02%, tan δ 1 x 10-5
  • Additional signal analysis capabilities like Spectrum Analyzer, Digital Scope and Data Logger are integrated.
  • Advanced, well-engineered test equipment, optimised 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  • Upgrade - Outdated Tettex bridge models (e.g. 2877, 2801, 2821, etc.)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
