The
TR1 is a fully automatic, Single Phase Transformer Turns Ratiometer,
that can be utilized for precision Laboratory, Manufacturing or
field test measurements. The TR-1 is a rugged, lightweight
instrument that automatically measures Turns Ratio, Excitation
Current and Phase displacement.
The TR-1 tests
the highest ratio (0.8..4,000) and the highest accuracy (0.1%) in
it's class, in the CT-Mode down to very low power rating (e.g.
10VA).
The TR-1 is extremely easy to use and operate and will work on all
configurations of single and multiphase transformers. With its
rechargeable battery it can be operated independent from line
voltage.
