The Three-Phase TTR310 Test Set is fully automatic, self-checking, self-calibrating, menu-driven unit. The test set measures the turn ratio, phase shift, and excitation current of power, distribution, and instrument transformers.

The test set can be used to test single-phase and three-phase transformers, both with and without taps in accordance with the requirements of the IEEE C57.12.90 – 1997 standards. For three-phase measurements, the test set is connected to all Three-Phases of the transformer to be tested.

Turn ratio, phase shift and excitation current readings are displayed on a large LCD. Transformer excitation current as well as phase shift angle helps to detect transformer shorted turns or an unequal number of turns connected in parallel.

  • Fully automatic operation.
  • Self-checking at power-up.
  • User-friendly, menu-driven operation.
  • Easy measuring of regular windings, tertiary windings, and CTs.
  • Three excitation test voltages: 80 V, 40 V, and 8 V.
  • Remote controllable.
  • Works in the presence of high interference/high voltage.
  • Displays % error vs. name plate with pass/fail limits.
