Product TR-Junior

Raytech's fully automatic single phase Transformer Turns Ratiometer

The TR-Junior is a fully automatic, Single Phase Transformer Turns Ratiometer, that can be utilized for precision Laboratory, Manufacturing, or field test measurements. The TR-Junior is a rugged, lightweight instrument that automatically measures Turns Ratio, Excitation Current and Phase displacement. The TR-Junior tests the highest ratio (0.8..4,000) and the highest accuracy (0.1%) in it's class. This system can operate in a continuous mode allowing very fast measurements of tap changer positions. The TR-Junior is extremely easy to use and operate and will work on all configurations of single and multiphase transformers.
