Description

  •  Used for testing single phase power and distribution transformers
  •  Design based on precision bridge measuring technique
  •  Unmatched accuracy (±0.1%) in a portable design

The Single Phase TTR, Transformer Turns Ratio Test Set, measures the turns ratio and exciting current of windings in power, potential and current transformers. Deviations in turns ratio readings indicate problems in one or both windings or the magnetic core circuit.

The TTR test set aids in identifying:

  •  Shorted coils
  •  Open circuits
  •  Incorrect connections
  •  Internal faults or tap-changer defects in step regulators as well as in transformers
