Turns Ratio Tester TRT40A

quote


Overview


TRT40A is a three-phase, fully automatic test set specially designed for turns ratio, phase shift and excitation current measurements of power, distribution and instrument transformers. TRT40A determines transformer turns ratio by accurately measuring the voltages across the unloaded transformer windings and then displaying a ratio of these voltages.

  • Test voltages from 8 V AC up to 125 V AC
  • Ratio range 0,8 – 50 000
  • The best ratio accuracy of 0,05%
  • Built-in tap changer control unit
  • Built-in USB flash drive
  • True three-phase and single-phase test
  • Automatic vector group detection
  • Detailed analysis of test results using DV-Win software
  • Pre-programming test-plans deploying DV-Win software
  • Lightweight – only 9 kg

 

True three-phase test voltage allows testing any type of transformer, including special transformers like phase shifting, arc furnace, rectifier transformers, etc. Together with optional Extension Transformer CVT40, it can produce up to 5 kV single-phase test voltage, allowing easy testing of capacitive voltage transformers turns ratio.

DV Win


trt_dvwin

The software provides numerous advantages, such as downloading test results from the instrument, acquisition of test results, creating graphs for easier analysis, creating test reports and saving them in several different formats.

When creating test plan, the DV-Win enables automatic calculation of nameplate voltages for all tap positions. The user is allowed to edit these voltages, save the test plan and recall it onsite. All results are displayed both numerically and graphically, making analysis as easy as possible. Test report, generated with single click, can be quickly customized, and directly printed or saved.
