Product presentation

The DTR 8511 is an easy-to-use DigitalTransformer Ratiometer, capable of measuring ratios on single phase transformers with high precision.

Operation of the DTR 8511 is fully automatic. No user calibration, range selection, hand cranking or tedious balancingis required.

Upon completion of a test cycle, the DTR 8511 displays:

  • Turn ratio
  • Test current
  • The percentage deviation from the nameplate

DataView® allows full control of the instrument. Data can be downloaded to the PC and analyzed.
