DV Power TRT-H Handheld Turns Ratio Tester

Handheld turns ratio tester TRT-H is DV Power phase instrument specially designed for measuring transformer turns ratio of single-phase and three-phase transformers.

Together with the turns ratio, the instrument also measures excitation current and phase angle. By measuring these two parameters, it is possible to detect failures, related to transformer core or windings, that cannot be spotted by measuring only the turns ratio.
