The BIDDLE Three-Phase Automatic TTR is an instrument designed to measure the turns ratio of power, instrument and distribution transformers. Deviations in ration, excitation current and phase deviations all indicate problems in one or both windings. The TTR aids in identifying shorted coils, open circuits, incorrect connections, internal faults, or tap-changer defects in load top changers or standard transformers.
