Megger TTR100 Hand-held Transformer Tester

The Megger TTR100 measures the turn ratio, phase shift, excitation current, dc winding resistance and polarity of single and three phase (phase by phase) distribution transformers, as well as power, potential & current transformers. The Single-Phase Handheld TTR Test Set is powered by rechargeable NIMH batteries.

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 transformers, the test set is connected to each of the three phases of the transformer to be tested, and measurements are made on a phase by phase basis.
